; Mr. Bowditch on the transit of Venus, June 3, 1769. 289 
observation of the internal contact by Mr. Hirst is in one place printed 
7h, 28° 57", in another 7h. 28' 47"; that of Mr. Dunn 7/, 29’ 28” and 
7h. 29' 48". The values 7h. 28’ 57", and 7h. 29’ 28", were used as 
best agreeing with the other observations. ‘The mean of the obser- 
vations of the first internal contact at Paris, made by Messrs. Messier, 
Cassini, Sejour, Chaulnes, Maraidi, Fouchy, and Bery, as published in 
the Memoirs of the Royal Academy of Arts and Sciences of Paris,
