It was from the correfponding altitudes of the Sun, 
taken the 3d and 9th of June, that I got the appa- 
rent times of the obfervations made at Caen j thefe 
times may be eafily verified, by the altitudes taken in 
the mornings of the 4th and 6th ; but I can fuffici- 
ently depend on the clock to difpenfe with that 
trouble. 
I return you, dear Sir, many thanks for your obfer- 
vations of the tranfit, which you was fo kind to fend 
me ; it is the meft circumdantial and compleat of 
any I have feen. What feems odd to me is, that 
neither M. le Monnier, as appears by his letters to 
me on this occafion, nor any of the obfervers at 
Paris, faw Venus ftretched out as I did, nor any kind 
of tail : by your defeription of this tail, there muff 
have been fome little difference in its appearance, to 
that feen by the perfon in my obfervatory here. 
If you think it will be acceptable to the Royal 
Society, I will take an opportunity of forwarding 
fome other obfervations and among the reft, an 
account of a very remarkable degree of cold, and its 
effedfs on different liquids in the beginning of the 
year 1768, to which 1 attended with great attention. 
In the mean time, I am. 
Dear Sir, 
Your mofi: obedient 
humble fervant,
