Mr Isaac Newton

Former Aquentance maketh me moore bould To trouble you with this In w^ch I have sent you Inclosed a Table of Observations of A Comet that appeared To us in Maryland Aug 14^th: 1682: Till Sep^t 12^th: 82: whilest it weare a Morning Comet having {Oct|c|ations} from whome made but Litle Observations thereof & therefore have Sett them downe at Randame on the bottom of the Table Onelye in Right Ascension and declination But from August 22 to Sep^t 12: for Every Night Except Sep^t y^e 1: 6: 8: & 9 sometimes being from home & sometimes Cloudey after the 12^th day of Sep^t we had for a weeke or better very Cloudey Evenings Till I suppose that It had got So neare the Sunn that no moore Observa\ti'/ with us could be made yet I thought once after being y^e 14^th of Sep^t; y^t I had seene it betwene Two Clouds neare uppon setting in y^e West{.} If So it Seemed to me Somewhat Retrograde but I had but a small glimpes theareof & therefore could make no Observations thereof But I suppose y^t Observations might be maid Long after in Most placeis wheare the wether was cleare: I suppose I was one of the first y^t Tooke not\ice/ thereoff in Maryland Being August y^e 14^th a morning Comet in y^e NorEast about ${10}^{\mathrm{degs}}$ Northwards of y^e North heade of ♊ Castor But seemed To mee to come to y^e Meridian w^th y^e South head of ♊ Pollux, or somew^{tt} after{.} It had than no Streame Cord or Taile at all that could be deserned Eather by the Eye or Elce by a prospective Glass as I could deserne neather would I trust my owne Eye in the cais but called upp others w^ch I thought might be stronger sited To have there Judgement of it for I was Suer y^t no Such star did belong to y^t place nor To any Other y^t I was aquen\ted/ with but they could not deserne any Steame {sic} & would have perswaided me y^t it weare a comon Ordinary Star but being so neare day & unprovided y^t I could make then but Litle Observations thereof onley I doe suppose y^t the declination then was Betwene ${41}^{\mathrm{d}}$: & :${42}^{\mathrm{d}}$ North & Right Ascen about 112 degrees But whether afterwards it did Increase in declination Norwards as it seemed to me the 17^th about $3^{{\mathrm{ho}}^{\mathrm{r}}\mathrm{s}}={30}^{\min }$ to be in neare ☌ with a Litle Star of the 3 or 4^th Magnitude being To y^e Southwards of the 2 small Br Stars in y^e Right \fore/foot of y^e Gtt Beare as I take it w^ch Small star cometh partley to y^e Meridian Betwene both of them \they Being 1 degdeg As under declin $48`$ or $49`$/ y^e Ri. Asc about ${130}^{\mathrm{degs}}$ declination of which {Sm^ll:} \^✱/ about ${43}^{\mathrm{degs}}$ North{,} y^e. {sic} ☌ as neare as I could make it onely by y^e Eye weare about $3^{\mathrm{ho:}}={30}^{\mathrm{m}}$ morning y^e comet bing {sic} about $30\prime$ or $40\prime$ min {sic} Southwards under it So by y^t Rule y^e Comets declination weare then about ${42}^{\mathrm{d}}={15}^{\mathrm{m}}$ this was the nearest ☌ of any that I Observed & I give you Notice thereof because I suppose y^t y^e Comet may have greater paralax than ether ♀ or ☿ It being than so swift in Motion as I suppose about $7^{\mathrm{degs}}$ & sometimes neare 8 degrees in 24 hours{.} To finde w^ch small fixtd star. {sic} Immaigine {sic} a Right Line from the Gtt Bears Back To y^e Litle dog ^✱ & it will pass by it or Nearly cut it < insertion from inline > ^{[Editorial Note 1]} < text from f 6:1r resumes > Or a Right line from y^e Pole star To \Betwene/ y^e Two Sm^ll Stars in Gtt bears \fore/foot & So Southwards about ${48}^{\mathrm{d}}={15}^{\mathrm{m}}$ from y^e Pole ^✱ you than cannot well miss \it/{.} on the Backside y^e Table is a Table of y^e Pole ^✱ {sic} Stars declination To Every 5^th degree of the Equinoct \{E}/ or Right Ascensio\ns/ Something Lightly Rune over & Allso the difference of declination of fixtd stars for 100: years for Every 5^th degree of there Right Ascension the Table I finde of ex\c/elent use To finde ye declination of stars by y^e Bow or fore staff or to finde out any unknowne star whose Right Asc & declin^t is given by y^e helpe of y^e Pole ^✱ & others severall wayes. I could wish y^t you would furnish me with a Table of Right Asc & declination of fixed stars for y^e yeare 1700: & as many as you please So y^t they Exceed Not y^e 3 or 4^th Magnitude or Rather than faile there Long^t and Lat'^t or Boath will do well for I finde by Severall Tables y^t I have by me they differ in Right Ascension very much So y^t If I should Take y^t pane\s/ To worke by the doctrine of plane & \or/ Sphericall Triangles by distances from Other Stars by y^e fore staff or y^e like without I knew ther True places I should make worse worke perhaps than I have done here in this Table thoug\h/ I had far Larger Instruments For by y^e Calculation of this Comet I had my Quadrant but 12 Inch Radius being of my owne makeing with such stuff as I could Gett being wood w^ch is heare far more apt to warpe & shrink then in England{.} therfore I would desire you to looke over my Table & Examine it with yours & give me If you please an Accompt of the difference for this day Receveing a Letter from Brother Edward Storer <6:1v> That it was first seene with you Aug: 7^th: 82 w^ch was 7 dayes before wee Tooke notice of it heare but he mentioned not what time it Ended with you who Righteth thus: The Same Comet (as {illeg}|is| Supposed) w^ch appeared decemb^r & January 1680: Appeared about y^e 7 day of Aug this yeare 82 in y^e Evening but not with So Long a Streame as it appeared before with but was not to be seene with them about 3 weekes after; & thats very strainge that there cann be such a supposed supposition as though a fier thats once burnt out & consumed y^e wood or stuff y^t feed it cann be Reneued againe By that feuell y^t it hath consumed It is a pretty conceipt {illeg} If it be true; this Comet Cast the streame Severall wayes heare first it was upright & held so for severall dayes than it bended somthing bowing towards Towards {sic} the pole ^✱ than bowing more & moore so y^t it pointed more & more towards the pole after wards pointed partly upright & than againe Contrary pointed to y^e westwards towards the South pole &c{} I sent unckle Babing a Letter daited about March 28: 1683 with my Observatio^s more at Large by Altitudes & Azimuth\s/ in w^ch I mentioned Gadburies 20 years Ephemeridies & a Good Large fore staff about 4 5 or 6 foot Long If it could so y^t it bow nor bend not by the wight of the vanes w^ch might be very usefull to me & Likwise in it did desire you If y^t you could Conveniently furnish me with a Table of Right Asc & declination of some of y^e Principall fixed Stars &c I sent him a Letter daited about May 22 1682 which as far as I can understand by Mothers & Brothers was not come to hand Sep^t 26: 82: w^ch Least his should faile againe makes me the more bould to Trouble \you/ with this Heare hath bene of Lait years besides this yeare many Notable ☌^s & oppositions both of Sun moon planets & fixed Stars w^ch by Reason of our great difference of Longitude To you w^ch I judge may be about 74 degres or better w^ch If well observed might be a great helpe to Astronime: Heare hapened A Lunar Eclipes: 1681: y^e beginning Aug ${18}^{\mathrm{day}}={08}^{\mathrm{hor}}={33}^{\min }=00″$ y^e midle ${18}^{\mathrm{day}}={10}^{\mathrm{hours}}=13\prime =30″$ y^e Ende ${18}^{\mathrm{day}}={11}^{\mathrm{ho:}}=54\prime =00″$ y^e Continuance $3^{\mathrm{ho}}=21\prime =00″$ parts Eclipse $\frac{3}{4}$ & $\frac{1}{2}$ or there Abouts{.} So If you please you may give me an accompt of our Longitude from London or Cambridg: Janu 17: $\text{16}\underset{\stackrel{\_}{\text{3}}}{\text{82}}$ Sun Eclipsed in maryland y^e beginning about $8^{\mathrm{ho}}={40}^{\mathrm{m}}$: y^e End about ${10}^{\mathrm{ho}}={30}^{\min }$: y^e Sun Eclipsed from ${16}^{\mathrm{degs}}$ To ${29}^{\mathrm{degs}}$ of altitude y^e parts Eclipsed about 5 digets on y^e undermost parte of the Sun\s/ bodey but I supose with you it was far greater{.} Heare hath beene of Late 2 great ☌ of ♄ & ♃ & y^e third now very neare w^ch I suppose will be before the Midle of may: y^e first ☌ as neare as I could well make it by reason of cloudey wether was with us ♄ Octob: 14: About noon ♄ Elivated Above ♃ 12 min semeing by y^e Ey To be twice his bredth from ♃ but by prospective Glass above 4 times: y^e Second ☌ of {illeg} ♄ & ♃ weare as neare as I could well make it the wether being Likewise cloudey for a day or Two before & affter ♄ Jan 27 about midnight ♄ above ♃ about 10 min there hath beene severall notable Lunar Eclipses he\a/re of Late y^e ☾ & Aldebaran y^e Last yeare the ☾ hid Aldebron severale times one I see w^ch I suppose Centarall: here hath bene Notable ☌ of Cor Leonis & ☾ & Likewise of ♂ & ♌ {} But I shall not trouble you with heare haveing no more at p^rsent but my dutye To unckle Babington & my Best Respects To all my frends with you I Rest at your Command To serve you Arthur Storer
