but on the other hand, he conftantly 
refers to the “Syfiéme du Monde,” 
by Laplace, which muft he allowed to 
evince an extraordinary degree of {ci- 
ence and merit! 
He begins bygiving an idea of the fun 
and moon, as well as defcribing the forms 
of the planets and comets. Aftronomers 
do not agree with him refpecting the 
planet Herfchel, and he has entirely 
forgotten to make mention of the pla- 
net Olbers, although difcovered within 
a very fhort period. 
The movements of the fun, as well 
as thofe of the ftars, are explained by 
that of the earth ; the various appear- 
ances arifing from the laws that govern 
all, are detailed, and the meafere of 
time, according to his theory, ought 
to commence with the 15th of March, 
a250, becaufe he tells us, that the 
grand axis of the ecliptic was, at that 
period, perpendicular to the equator. 
Ajiter this follows an account of the 
inequalities of the moon, and a theory 
ef eclipfes. In the article of comets, 
the formulz that regulate their move- 
ments are defcribed, but the demon- 
ftration is not appended ; we are how- 
ever prefented with a fcheme of the 
elegant mode pointed out by Citizen 
Laplace, by means of three different 
equations. ; 
Much pains are very properly be- 
fiowed, in explaining the figure of the 
earth, the different methods employed 
in determining it; the manner of find- 
ing the longitude and latitude, &c. 
When defcribing the theory of the cen- 
tral forces, he produces the beautiful 
theorems difcovered by Huygens, and 
he propofes to fubftitute inftruments 
for the purpofes of menfuration, in the 
place of the areometers. The lat lec- 
ture is confecrated to the flux and re- 
flux of the tide, and the explanation 
of the effects of the fun as well as the 
moon upon the ocean.

General Serviez,who appears to have 
acted for fome time in a civil capacity 
in the Lower Pyrenees, formerly drew 
up a defcription of that department, 
which like the prefent, was printed 
and circulated at the expence of the 
“Government. 
He is of opinion, that the wafte-land 
which he propofes to till, and which at 
prefentonly maintainsa few half-ftarved 
cattle, may be made to nourifh men, 
and feed thoufands of families. He at 
the fame time obferves, that feveral 
experiments have already been tried 
with fuccefs, and he propofes to follow 
them up by more upon a larger fcale. 
The Council of the Commune of the 
fame department appears to have been 
greatly alarmed at the General’s plans, 
and has drawn up areply, in which 
all his aflertions are either combated or 
denied. Upon this occafion the fame 
arguments have been recurred to in 
France, that are ufually employed in 
this country againft the inclofure of 
commons; the author in a well written 
rejoinder, has endeavoured to overturn 
the pofitions of his antagonifts, and he 
remarks, that, according to their rea- 
foning, it would be ufetul to re-eftab- 
lifh the tithes of the clergy, aad the 
feudal rights of the nobles.
