in Italy. 
At Lyons the municipality, whom F had solicited to re=

15 pages in 4to. Second memoir, upon the famous devia-

explains the machines of M. Loysel, and which have the 
advantage of several more figures than my Astronomy for the — 
Ladies. He will give the development of them in his subse-
