1817.] Scientific Intelligence. 159 
Lagrange had printed the first sheets when death snatched him 
from the sciences. M. de Prony undertook to complete the edition; 
and he was assisted in revising the proof sheets by M, Garnier, 
Professor at the Royal Military School. The manuscript of sections 
seventh and eighth was found in great order. That of section ninth 
was very incomplete, the first paragraph alone being finished. 
MM. Prony, Lacroix, and J. Binet, examined his manuscripts 
with the greatest attention, and were convinced that the author had 
proceeded no further, and that of course nothing had been lost. 
M. Binet undertook the disagreeable labour of comparing the 
subjects and the notation of the old edition with what was printed 
of the new. Advantage was taken of all the marginal observations 
found in Lagrange’s copy written with his own hand. Some things 
relative to rotatory motion, too incomplete to form a paragraph, 
have been thrown into a note at the end of the volume. 
Another note has been formed of a remark likewise found among 
the manuscripts. It relates to the problem of determining the 
orbits of comets, a problem treated of in the third paragraph of 
section seventh. 
The volume is terminated by a complete list of the works of M.. 
Lagrange, communicated by M. Lacroix. At the end of this list 
we see with pleasure that a Minister, a companion and great ad- 
mirer of M. Lagrange, caused Government, during his adminis- 
tration, to purchase all the manuscripts left by this illustrious, 
mathematician; and at his request the Class of Sciences has 
named a commission to make choice of those that are fit for print- 
ing. The others will be classed, and placed in the library of the 
Institute.
