1770. April 28, at g h 48' 13", apparent time, Mr. 

 Bradley and I, both at the fame inftant, obferved 

 the immerfion of £ c5 ' by the Moon. The emer- 

 fion was not taken,. ; By comparing this with Mr. 

 MafkelyneV obfervation, our longitude comes out 

 4/ 23"! Weft from Greenwich. 



j jyo. July 2 1 ft is marked for an eclipfe of Juptiter's 

 fourth fatellite in the Nautical Almanac ; but the 

 Connoiifance des Temps notes it as a conjunction 

 only, and remarks, that the fatellite- would rafe - 

 the fhadow > without difappearing ;; .which we 

 found to be true, Yor we both faw the fatellite 

 the whole time which is marked for its dura- - 

 tion, though,, at the middle, it appeared extremely/ 

 faint. . 



Thefe obfervations were made before our Obser- 

 vatory was flnifhed ; but that being completed in the 

 month of September* and furnifhed with an excel- 

 lent (riiough fmall) mural quadrant and tranfit in- 

 urnment, both made by that eminent artift Mr. John, 

 Bird, we began to obferve meridian tranfits, from 

 which I (hall feleft thofe that were made for deter- 

 mining the folftices, and the oppofitions of the three 

 fuperiour. planets, • which I (hall tranferibe, juft as ? 

 they were taken, excepting, only making the nev 

 cefTary allowance for .the. ..error of. the. line, of .col* - 

 limaiion.;.
