can edition, especially in view of the excellent style of the typography and 
engravings, which are very creditable to the publishers. As a manual for 
the guidance of the student of general chemistry, the " Elements " of Prof. 
Graham enjoy deservedly the very highest rank among English chemical 
treatises. 
Dictionnaire des Alterations et Falsifications des Substances Alimentaires, 
Medicamentenses et Commerciales avec Vindications, des moyens de les re- 
connoitre, Par M. A. Chevallier, Pharmacien Chimist, Prof, a Ecole 
de Pharmacie, etc. Vol. II., Paris, 1852, pp. 580 with plates. 
The first volume of this work was noticed succinctly on page 95, vol. xxiii. 
of this Journal. The present volume, which completes the book, is more 
extensive than the first, and has required, from the nature of several of its 
articles, a greater amount of labor. The subjects extend from L to Z, and 
include a large number of important articles in medicine and the arts. 
Among the subjects which have attracted most attention among alimentary 
substances, are milk, honey, pepper, common salt, sugars, vinegar, and wines ; 
of commercial substances, papers, resins, saltpetre, sal soda, soaps, sulphates, 
and tobacco; and, of the very numerous medicinal substances, a few are 
magnesia, manna, sulphur, opium, cinchona, scclmmony, syrups, sulphate of 
quinine and other medicinal sulphates. 
M. Chevallier does not confine his subject to artificial products, but in- 
cludes nearly the whole range of medicines, barks, leaves, flowers, seeds, 
but many of the articles go no further than the same subjects are carried 
in the works on Materia Medica, and are introduced as much to swell 
the size of the work as for any tangible means of judging they offer. 
The work, as the title indicates, is by no means solely directed to the 
pharmaceutist; indeed its most elaborate articles are on subjects connected 
with the manufacturing arts, as soaps, vinegars, wines, breadstufFs, milk, 
etc. As a whole, the tl Dictionnaire , ' J is well worth a place in the pharma- 
ceutical library, and contains a large amount of information derived from 
innumerable sources. We shall occasionally publish a few extracts 
from it. 
The Communication of Dr. W. Manlius Smith, of Manlius, New Ynrk, 
having arrived too late for this number, will appear in the October issue. 
Our Journal. — We consider it objectionable, as a general rule, to issue 
a journal before it is due, and have endeavored to be as punctual to the 
beginning of the month as possible. In the present instance, to accommo- 
date ourselves, we have served our subscribers perhaps before their appe- 
tites have awakened.
