1. The Arithmetic of Emilius, con- 
taining the Augmentation, Diminution, 
and Comparifon cf Numbers, &c. By 
Em. Deve Ley, Profeflor of Mathema- 
ticsin the Academy of Laufanne. 
z. The Natural Philofophy of Emi- 
lius, or Principles of the Science of Na- 
667 
ture, prefented in an order entirely new, - 
and demonftrated by means of fimple ex- 
periments, &c. By the fame. i 
3. An Introduction to Algebra; and 
4. An analytical Treatife on Method. 
The two firft of thefe works have been 
analyzed and commented upon by Pro- 
feffor Struve and Doétor Verdei], who were 
expreffly nominated for this purpofe by 
the Council of the Canton of Vaux. 
I. “It appears;”’ fay they, ** that the 
Arithmetic of Emilius was originally pub- 
Iifhed in 1795. It was firft remarked on 
account of the purity, the precificn, and 
the clearnefs of the ity!e, as well as for 
its analytical and inventive method, 
which had not hitherto been introduced 
into the elementary works of arichmetic. 
It, therefore, in a fingular degree, at- 
tragted the notice of the public 5 and the 
French Government accordingly, during 
the feventh year, placed it in the hit of 
elementary treatifes, dedicated to the ule 
of thofe who undertake the education of 
youth. 
s¢ The fecond edition, which appeared 
in 1802, feemed ftill fuperior to that 
which had cbtained fuch a flattering tel- 
timony: the author has alfo rendered his 
demonftrations more general, and this is, 
undoubtedly, accompanied with confider- 
able advantage. In addition to fome al- 
teritions refpeCting ordinary or vulgar 
fraGtions, we are aifs prelented with the 
folucion of feveral interefling queltions, 
befides fome new chapters; the whole ter- 
minates with the expofition of the new 
fyftem of weights and meafures, and a 
comparative eftimate prefenting, at one 
view, the reciprocal connexions between 
the new and old meafures of France, 
England, Zurich, and Berne. 
II. Of the Natural Philofophy of Emi- 
-YVius.—We are told that the author hath 
affixed this title to his work, not becaufe 
he has deftined it for fcholars fuch as 
Emilius, or that his wateral philofophy 
refembles that of Rouffeau, but on 2c- 
count of its affinity to the method of that 
celebrated man, the fpirit of which he 
bas endeavoured to imitate. Ihe work 
is divided into two fections, the firlt of 
which treats of the repofe of bodies, and 
the fecond of their motion. Each of 
thefe fections is fubdiviced into chapters, 
in which the author fucceffively confiders, 
firtt, the repofe of folids, the repose of lie 
guids, the repofe of elafite fiutds, then the 
motion of folids, the motion of liquids and 
elafiic fluids, and, finally, of the ma- 
chines deftined for the afiitance of man- 
4R2 kind,
