and a kind of deer about the fize of a lap-dog : I 
fent lorae for the governor, but they died by the 
way. 
I am now to acquaint you, that, having procured 
a telelcope and (top-watch, I made my observations 
upon the tranfit of Venus, which happened here on 
the 4th day of June, 1769.

* Whence the planet’s centre was on the fun’s limb at 
■7 h 1' 36"; and this compared with an obfervation of the 
central egrefs or ingrefs made at a diftant place will give the 
fun’s parallax; the other neceffary elements of the calculus be- 
ing well eftablifhed. Tn the mean time we fee, from the Con- 
noiflance des Terns for 1769, that Phefabad in Bengal, wliere 
Captain Rofe obferved, is 8i° 45' eaft of Paris. 
The watch had been regulated the preceding day, by equal 
altitudes of the fun ; the fun’s altitudes, at the two contacts, are 
likeaife marked in the Captain’s letter; but this part of the 
work he had probably entrufted to a lefs fkillful obferver, while 
his own attention was engrofled by the telefcope and the watch ; 
as 1 find the difference of the times correfpondent, to tbofe 
altitudes, does not agree with the interval of the contacls ; for 
which reafon they are here omitted.
