The Declination for April the loth, in the Meridian of London is o8d. 05m. increafing, and the daily Difference at that Time is 22m. therefore in this Table look in the Head thereof for the Number 22, or neareft thereunto, if not in the Table ;then look on the Left-hand of the Table for lOfd. (or the neareft thereto) the Longitude Iam in, and in the common Angle of meeting is 6Min. which is to be dedmfted from the Declination in the Meridian of London aforefaid 8d. 05m. and the Remainder will be the Declination for that Meridian, or the Longitude Iam in, which is o8d. 58m.

Note, the Sun’s fetting is annexed to each Table, but the_ Sun’s Amplitude only-to that for Nortli Declination, becaufe it’s the fame (as to Quantity) for South Declination. The Sun’s fetting is Hours and Minutes, but the Amplitude. is Degrees and Minutes, having (d) over the Degrees-, and mover the Minutes. - F3.% 86 "^he Mariner's Comfajs ReQified. By thefe Tables (being Sun Dials for all Latitudes) may be known the Time fthe Day, the Sun being vilible in any Part of the Demifphere as true and exadi: as though he was upon the Meridian ;Alfo his Riling, Setting, and Amplitude.. The like may be known by any Star, whofe Declination doth not exceed 23d. zgm. as will be evident by the following Propofitions. Tropofttion i. 'T 'HE Latitude of aPlace, the Sun’s Declination, and his Bearing being given ;to find the Hour of the Day. Note, By Bearing is meant the Azimuth or Point of the Compafshe isuponj and that is found by fetting the Sun with an Azimuth Compafs, which is the trueft Way, proper Allowance being made for the Variatiou, and is to be preferred before fetting the Sun with acommon Compafs. 7he Refolution of this Propojition is thus ; j. Seek in the Sun Dial Tables for the given Latitude. 2. At the Head of the Table feek the given Declination, or the neareft to it. 3. Find the given Bearing among the Points of the Compafs jn the Left-hand Column. 4. Then look ftraight to the Right-hand of the Bearing, till you come right under the Declination (before found) in the Head of the Table, and what Number you find there is the Hour, required. '"i Example i. In the Latituae of 30 Degrees, the Sun having 15 Degrees North Decimation, 1defire to know at what o’clock the Sun cometh upon the SW. Point of the Compafs ? Look'for the Table belonging to the Latitude of 30 Degrees, which is in Page 54, and iri the Head thereof, feek for 15 Degrees in the,Column under North Declination, sMd on its Left-hand Side for SW. and.then in thecommon .^ngle of Meeting you 'vyiil find the Hour of the Day to be oh. 58m. that is 58,(|Sffin.- pall 12 o’Clock, the Time required. Ettample ^he Manner's Comfajs KeSiiJied. .8/ ExanrpU 1.Idefire to know at what o’Clock the Sun cometh to the SW. in the Latitude of 30 Degrees, his Declination being 15 Degrees South ?Jnjiver, 34 Minutes paft 2o’clock. For if you turn to the Dial for Latitude 30 Degrees, in 54? in the Table for South Declination leek I5d. at the Head of.it, under which, and right againft SW. (on the Left-hand) you will find 2h. 3401. the Tin e of the Day required. .. If the Decimation be not the fame with the Declination in the Head of the Table ;then look under that DecI ination which is neareft to the Declination propofed. But more exadlly thus, Find the.Hourfor the next Declination both left and greater than the Declination profojed, and take the Difference of thofe Hours, as alfo of the Declination belonging to them ;Then fay, As the lall Difference is ta the firft Difference ;fo is the Difference between the Declination propofed and the next lefs in the Table, to afourth proportional, which add to (when the Hour in the Fable increafeth) or (when it decreojeth) fubflraff from the Hour belonging to the lefs Declination aforefaid, and you will have the Hour required exatf to the Declination propofed. .., Example 3. Admit the Declination to be 18 Deg. 20 min. North, Idefire to know at what o’Clock the Sun cometh upon the WSW. Point of the Compafs, in the Latitude of 30 Degrees ? Tn the Table, the neareft Number to 18 Deg. 20 Min. is ryd. 30m. Then under lyd, 30m. and againft WSVV. is ih. 42m. which fheweth that the Sun cometh upon the WSW. Point of the Compafs, at 42 Min. paft one o’Clock. Now becaufe the Declination propofed, and the Declination in the Head of the Table are fomewhat 'iiTerent ;therefore you may make, aProportion very eafily, thus, under jyd. 30m. and againft WSW. you will find F4ih. 54 Mariner’s Compajs ReSiified. upper Circle reprefenteth the Compafs that you fteer by, which is fubje.vt to Variation :But the outward or under Circle reprefenteth atrue Compafs that never varieth. An^ by It you may readily reftify your Compafs when it doth vary ;thus. Always-bring the true Point of Riling or Setting on the outward or under Compafs to touch the falfe Pointof Rifing or Setting on the inward or upper Compafs, there let the Inftrument hand. As in the foregoing Propofition ;The Eaft Point is the true Point of Rifing, and ESE. Point is the falfe Point of Rifing ;therefore bring the Eaft Point on the outward or under Compafs, to touch the ESE Point on the.invyard or upper Compafs. Then the Points that are on the outward or true Comjiafsdo explain the Points that are upon the inward or fteering;C©rhpafs ;fo that according to this .Obfervatiohi the NNii'.'t’pint on your Compafs, is the true North Point ; and the '^oEtht's the' true NNW. and the NW. is the true WN'W'. an^ the Weft the true W'SW. Point ;as plainly appears by' the- Redlifier, Note, The true Points are always counted on the outward Circle or Compafs. • •iThis Inftrument in Wood, is larger than this Figure, •and. there the Points are divided into Halves and Quarters; ;as alfo each Compafs (in fome) is divided into 360 Degrees niumbercd from the North and South, (both ways) towards the Eaft.and Weft, ending therein 90 Degrees. '-A'.rightKnowIedge of the Quantity and Quality of the of the Compafs in different Latitudes and Longitudes; is of the utmoft Importance, not only in the prejCeding Propofition, biit in all others where are required, and efpecially in corredling the Cnurfes fteered by aShip at Sea ;for which Purpdfe an accurate Vai'iation Chart conftrudtqd from more than FiftyT'houfand adtual Obfervations, by IVilliom M'Witaine^ F,.R,, SV fold by Mount and Page, bn Tower Hill. jThe.'

In the Table for 50 Degrees (in Page 74) feek the Declination 20 Degrees North at the Head of the Table, under which, and right againft ©fet is 7.43, which, flievveth. the Sun fetteth at 43 Minutes after 7in the Afternoon ; which fubtraft from 1ah. the Remainder 4h. 17m. is his Riling. In hke Manner under the Sun’s Declination 2od. and againft Sun’s Amp. is 32d. 8m. the Sun’s Amplitude; that is, ..Eall Northerly at his Rifing, but Weft Northerly at his Setting. •. Note I. The Amplitude is always of the fame Name with the Declination, for that Reafon the Amplitude is fet only for North Declination, being the farne in Qi^iantity for S'outh Declination, only in Quality it is the contrary. Note 2. The Sun’s Riling forNorth Declination., is the Setting for South JDeclination ;For that Reafon, the Table hath only 0fet, both for North and South Declination :Yet they ferve.for both Rifing and Setting, by looking contrary to the given Declination. Wherefore to find the Sun’s Riling when he hath North Declination, look under South Declination ;and when he hath South Declination (to find his Rifing) look under North Declination. Note-p,. In South Latithde with South Declination, alfo in South Latitude with North Declination, the Sun’s Rifing and Setting is the fame as in North Latitude with North Declination, as alfo in North' Latitude with -South Declination. 'There Xhe Mariner’s Compafs ^e5l.ified. 97 ^ Therefore thofe Tables are as iifeful in South Latitude as ^ in North Latitude; if North Declination in thefe'Tables ; be counted for South, and South for North. .^/.

(being fpme four, fome two Tabbies,' one Page) and fixty-one in all.

The firft and fecond Columns (under North Declination) as alfo the fourth and fifth Columns (under South Declination) contain the Points, and each Quarter of a Point of the Compafs, of both Rifing and Setting :Thus, EaU, Weji, under which is i, 2, 3;that is Eajl or Weji IQuarter, 2Quarters, 3/Quarters, Northerly or Southerly ; then E. by N. W. by N. under which is i, 2, 3;that is E. by N. or W. by N. iQuarter, 2Quarters Northerly, &c. Thefe Tables are ready Helps for finding the Variation of the Compafs with Eafe, and fufficient Exadfnefs, as is evident from the following Explanation. To find the Point of the Compafs that the Sun rifetb or fetteth with, at any Time of the Year. p' IRST, feek the Sun’s Declination in the Table of Declination for the Time propofed ;with which enter the foregoing Table, finding the Latitude in the Head of the Table, and the Declination in the third Column ;againft which, on the Left-hand, if it be North Declination, but on the Right-hand if it be South Declination, is the Point of the Compafs that the Sun rifes or fets at, according tp theTitles at the Head of the Table. Note, Thefe Tables Ibew the true Points of the Sun’s Rifing and Setting; fo that you may readily know at any Time, feeing the Sun rife or fet, the Variation by an ordinary Meridian Compafs. There are fome Compaffes not touched fo well as they ought to be; others in Tirne will grow weak, or lofe their magnetic Virtue. Now by thefe foregoing Tables you may very readily difcover any of thefe DefeSis. It may indeed be objedled, they cannot fee the Sun by an ordinary Meridian Compafs, fo near as is required I2To 1^2 The Mariner's Compafs ReSiiJied. To this Ianfwer, it’s as eafy to fet the'Sun by the Compafs, as to fleer a.Ship by it •, for expert Seamen can fet the Sun, or Headland, to near aQuarter of aPoint by their Hand, (but with Sights much nearer the Truth.) The Poflure to obferve in fuch Cafe, Iadvife, is thus : Set the Compafs about two Feet high, and diredling your Hand towards the Sun, note what Point, Half Point, or Quarter Point, the Sun rifeth or fetteth on ;then in that Table belonging to the Latitude, fee whether the Sun rifeth or fets that Day upon the fame Point, found by Obfervation ;if they agree, there is no Variation ;but if they do not agree, the Compafs is hot true, or there is Variation ;and the Variation is fo much, as is the Difference between the Obfervation and the Table. Example i. Admit fn Latitude 30 Degrees North, tlie Sun having 9’ Degrees 44 Minutes North Declination jI ©bferve the Sun that.Day to rife upon the E.N.E. Point of the Compafs. .Idemand the Variation. Jn the Head of the foregoing Tables, look for the Latitude 30 Degrees ;and in the third Column for 9deg. 44 min. North Declination ;and againft it (under ©rife) is E. by N. which fheweth that there is one Point Variation. For it appears by the Table, that the E. N. E. Point on the Compafs is the true E. by N. Point ;and'the E. by N. (as it is upon the Compafs) is the true E. Point ;the Eaft Point is the true E. by S. the S.E. is the S.E. by S. and the South is the S. by W. the W. is the W. by N. arnd This plainly appears by the ReSlifer, if you bring the E. by N. on the outward Circle, fight againft the E.N.E. on the inward Circle. No'w fuppofe we were to obferve the Sun at his feting, in the Latitude of 30 deg. with. Declination 9deg. 44 min. North as abovefaid, we fhould find the Sun to fet exadlly at Weft by the Compafs, although in the Morning ^he Mariner's Compafs Re5lified 133 Morning we did find the Sun to rife at E. N. E. Iknow this will appear aContradidiion to fome ;but if you caft.your Eye upon the ReEiiJier, you may fee it’s acertain Truth. Example 2. In Latitude 37 deg. North, the Sun’s Declination 8deg. 58 min. North, Iobferve the Sun to rife E. by N. by the Compafs ;Idemand the Variation In the Table that belongs to 37 deg. againft 8deg. 58 min. North Declination, and under ©rife is E. by N. which jfheweth there is no Variation, becaufe the Obfervation agrees with the Tables. Note,'\i the Declination for the Day propofed be not the fame with the Declination in the Tables, then have Regard to the neareft, allowing for the Difference, by the Rule of Proportion. Example 3. In the Latitude 37 deg. North, fuppofe the Sun’s Declination 10 deg. 15 min. North, Idemand the Point of the Compafs the Sun then rifeth upon ? In the Tables neareft to 10 deg. 15 min. is 11deg, 12 min. againft which the Sun rifeth E. by N. aQiiarter N. and fets W. by N. aQuarter N. but in the Tables for 37 deg Latitude, the Declination propofed is near about the middle, between 8deg. 58 min. and ix deg. 12 min. Therefore the Sun rifeth E. by N. half aQuarter N. and fetteth W. by N. half aQuarter N. Underftand the like in any Cafe, let the Declination be what it will, and in any. other Latitude. .Example Admit in Latitude 38 deg, aotn. North, and Declinationigd. 50m. South :The Sun rifeth upon the E.SE. Point of the Compafs, ;Idemand the Variation ? In the Table for Latitude 38 deg. and againft 19 deg. 41 min. (the neareft to the given Declination) is ES.E. aQuarter S, w.hich Iheweth that there is aQuarter of a Point Variation. For the E.S.E. Point i? E.S E. aquarter S. and the North Point is N. aquarter E. For, if you bring ESE. aquarter S.on the outward Circle of the ReSiiJier right agamft E.S.E, ,on the inyyard Circle, then S.S.W. on the Compafs 134 'The Mariner's CompafsReBified. Comp&fs is SSW. aquarter W. and SEi is SE. aquarter S.,and E. is E. aquarter S. And fo for any other Point, Half point, or Quarter point, by calling your Eye upon the ReHifier. Note^ Thtk Tables fliew the true Points of Rifing and Setting, and the outward Circle on the ReSiifier doth the fame ;but the Compafs, when it dilFereth from the Tables, fhews afalfe Point ;and the inward Circle on the ReHifier doth the fame. Example 5. Admit in Latitude 47d. 24m. North, the Declination I5d. 2m. South, the Sun’s rifing E. by S. by theCompafsi; Idemand the Variation. By the Tables the Sun Ihould rife ESE, therefore there is one Point Variation :For if you bring ESE. on the outward Circle of the Refitjier, over againft the E. by S. on the inward Circle, then the N. by W. on the Compafs is the true North pointy the NW. is the NW. by N. and the S. by E. is the true South Point. By this Time Ifuppofe the Reader able to difcover how much the Variation is, and how to reckon it without any Geometric Demonftration, or Arithmetic Calculation. Note, If you have any odd minutes of Latitude, go to that Table neareft the Latitude you are in. Icome now to refolve aQuellion which fome are puzzled with ;and that is this : S^ueft. If the Sun rife at ENE. by any Compafs in any Latitude, Ihould not he fet the fame Day at WNW. by the fame Compafs, and in the fame Latitude ? Jnfwer. If there be no Variation he will ;but if there be Variation, he will not. The Reafon is evident by the ReSilfier. By thefe Tables you may know upon what Point of the Compafs any of the Stars rife and fet in any Latitude the Tables contain, either North or South, if the Declination doth nor exceed the Sun’s greateft Declination. Example 6. Let it be required to find the Points of the Compafs the Bull’s Eye rifes and fet's with, in the Latitude qf 50 Degrees North. -The The Mariner’s CompafsReElified. 135^ The Declination of this Star is 16 Deg. North ;in the Table that belongs to 50dt againft 16 Deg. North Declination, the true roint of Rifirig is E.N.E. aQuarter N. and the true Point of Setting W.N.W. aQuarter N. Underftand the like for any other Star, whofe Declination doth not exceed the Sun’s greateft Declination. TheUfeofthe RECTIFIER. '^HIS Inftrument, as before defcribed, (in Page 93, 94, and 95) containeth two Circles, or Compaffes, one within the other ;but as it is made of Wood, the one moves upon the other, and by it the Compafs, when it varies, may be rectified as follows ': Bring the true Point of Rifing or Setting (as the Table flieweth) on the outward or under Compafs, right againft the falfe Point of Rifing or Setting (as your Compafs flieweth) on the inward or upper Compafs jth.eh 'will the under Compafs rectify the upper. ^ Example 7. Adniit in Latitude 45d. N. the Sun’s Declination being 7d. 56m. South, the Sun fetting upon the W. by N. Point of the Compafs, Idemand the Variation ? The Sun, if there be no Variation, will fet at W,. by S. and rife at E. by S. as appears from the Table ;therefore it is plain that there are two Points Variation. Bring the W. by S. Point on the outward Compafs, right againft the W. by N. Point on the jnward Compafs ;then the Points upon the outward Compafs explain the Points that are upon the inward ;fo that according to the foregcyng Oblervation, the N.N.E. Point on the Compafs is the true North :The North is the true N.N.W.jhe W, by N. is the true W. by S. the S.E. by E. is the true E. by S. And fo for any other Point of the Compafs by only looking on the ReSlijier.

T> EFOREthe Invention of Hadley’s Quadrant it was common and ordinary at Sea, to take the Meridian Altitude of the Sun or Star with this Inftrument, and by it to-find the Latitude the Ship is in. To perform which obferve the Precepts following ; 1. Note.* The 1o, 30, 60, and 90 Crofs, are to be ufed according as the Meridian Altitude is more or lefs ;that is, if iefs than lod. ufe the 10 Crofs :if between 10 and 3od. ufe the 30 Crofs ;if between 30 and 6od. the 60 Crofs, more than. 60, ufe the 90 Crofs, 2. Having confidered which Crofs (according to the judged Altitude of the Obje£l: intended to be obferved) is fuitable, put it on the Staff, fo that the flat Side of the Crofs may be towards the flat or Square End of the Staff j. Then. 3. Hold the flat End of the Staff (as at A) to the Corner of your Eye; there let it reft upon your Eye Bone, as near the Corner of your Eye as you can, fo it doth not hinder your Sight. 4. Then look to {he upper End of your Crofs (as at C) for the Sun or Star, and at the lower End (at B) for the Horizon. -. 5. But if at the lower End of the Crofs you fee all Sky and no Water, then draw^the- Crofs alit.ie nearer to your Eye. 6. ifon the contrary,'- you fee all Water and no Sky, then Aide the Crofs alittle farther from you, 7. Then, if you fee the Center of the Sun or Star at the uiiper End of th» Crofs, and the Horizon at the lower End,' the Crofs ftands as it ought. 8. Wait till the Sun or Star be on the Meridian, making Obfervations often ;and as the Sun or Star rifeth, draw the Crofs alittle nearer to your Eye. g. If the Sun or Star be fallen, you will not fee the Horizon, for the Water will hide it from you, and then Ob-' fefving is over at that Time. Stir not the Crofs out of its Place, only fee at ^what deg. fsfc. it refteth on that Side 254 Compqfs ReSitfied. The Sea-Coafts of France. Names-of Places.
