Reviews ofthe First Edition of this Work :
This Work will prove highly acceptable to those who
wish to attain a pradical'acquaintance with the science of
which it treats. The Author exhibits throughout the Work
great degree of chemical knowledge ; and his method of
communicating knowledge to others is engaging. With the
pradical part of the various processes in chemistry he seems
to he well acquainted ; and the #fcuracy. and precision With
which he describes them will render this Work valuable;
not only to tyros but toproficients in the science." —Philo-
soph. Mag.
• .4 We think this Work, as a►► elementary treatise, highly
valuable. It is clear. explicit, and comprehensive.. The
different properties of bodies are detailed with perspicuity,
and supported by easy apposite experiments. The particular
descriptions are preceded by a clear account of the nature of
chemical anion, and the fans that demonstrate the attrac-
tion and repulsion of bodies. " Critical Review, v. 39. p. 38..
" This work is drawn up for the use of such as arc unac-
quainted with chemical science, and will doubtless prove
acceptable' to the numerous cultivators of ;he Science,, of
C hernistry."—N icholson's Journal.

Testimonies in Favour of this Work
• 4.1 We have no hesitation in saying, that this Work cannot
. fail to prove extremely useful. The first volume, in parti-
cular; is-executed in a manner highly creditable to the Judg-
ment,iiiti abilities of the Author, who has rendered an essen.'
tial service to his Country by its publication. Should the
• Woik meet with that reception which it merits from the pub-
lic, we have no•tioubt but a new edition will soon be de.
inandecl."-- Phil. Mag; No 95.
On the whole, we regard the present as a useful and re-
spettable Treatise. We have been much entertained and in-
struded by the Second Volume ; though we can do little
more than state in general terms, that the descriptions, in ge--
neral, arc full and satisfactory. This part of the Mechanics
we consider to be highly useful ; and, indeed, there does not
now occur to our minds any English Work of the same plan
and extent: The plates are neatly iexecuted, and by a very
judicious arrangement placed by theipselves in a separate
volume.—Critical Review, May,
14 Though these volumes are of the oclavo size, yet as the
type Is small, and the page full, they-contain a vast quantity
of materials."'

As.an elementary work this Treatise on Mechanics is by
far preferable to any other work extant, at least in the Eng-,
lish language. The style is perspicuous, the arrangement of
materials is in very few places susceptible of improvement ;
the information it contains is extensive, and the plates are
elegant ; we do not therefore hesitate to recommend it to the
attention of the scientific world."—British Crit. Aug tBos.
