T had a river and a meadow between the Sun and 
me; the exhalations which rife from fuch places, 
efpecially towards the evening, produced, no doubt, 
that undulatory motion of the Sun, which mud 
render obfervations made in fuch circumdances 
more or lei's dubious. 
In fhort, I lhall make two remarks on our ob- 
fervations: the fird, that it feems odd, that the 
obfervation of the external contacts, which, for the 
reafons beforementioned, I judged had been made 
too late, agrees neverthelefs both with yours and 
thofe of Greenwich : fecondly, that although the 
internal conta&s be marked by us fooner than by 
any other obfervers, except thofe of St. Hubert; we 
kept, neverthelefs, the mod fcrupulous filence, nor 
did any motion indicate to the others, the times each 
wrote down ; moreover, we were all three convinced 
that Venus and the Sun were feparated, when we 
began to count the clock. However, 1 can but con- 
lider it as a misfortune, to have left my obfervatory, 
where the Sun’s limb appeared perfectly well deter- 
mined, even after the internal contacts, and not in the 
lead: affected by any motion or undulation, which 
were fo troublefome to us; luckily I left a perfon in 
it, who did not negleCt thefe favourable circum- 
dances; and the obfervations there made are the 
more intereding, as the weather did not permit the 
external contacts to be obferved, in any place from 
Caen to Bred, no more than at Paris nor in its 
environs.
