I fhall conclude this account with a few remarks L 
think it necefiary to make on the manner in which 
my obfervation of the tranfit in India, in 1761, was., 
inferted in the Philofophical Xranfadions. . Lam. 
very much grieved, that the obfervations of the equal, 
altitudes and meridional tranfits for regulating my 
time-keeper were altogether omitted. Had this not; 
been the cafe, every one might have judged of the; 
care and pains I. took in that diffcant part of the world, , 
as well in making feveral of my inftruments myfelf, ,

fidence was to be given to my obfervations might be 
eafily feen. Monfieur Pingre;^' would have had no . 
occafion to lament that I did not acquaint the world in: 
what manner I.obferued the equal altitudes to determine
