332 —CO Notice of a Manual of Chemistry. 
student, if not satisfied with the condensed or abridged account, 
knows where to seek for farther details. It is pleasing to observe 
how scrupulously the author “renders unto Cesar the things that 
are Cesar’s,” and bestows honor upon whom honor is due, by 
crediting every important observation or discovery to its rightful 
owner; an act of justice that is too often neglected. 
Dr. Webster alludes to Prof. Bache, the accomplished editor of 
the American edition of Turner’s Elements, in well merited terms 
of commendation. To Mitchell, Hare, Silliman, Jackson, Hayes, 
Torrey, and others, that we with pride rank among our prominent 
scientific men, he gives due acknowledgment for such of their 
labors as come within the scope of his work. The various valu- 
able pieces of chemical apparatus figured and described, which 
are the products of the inventive genius of some of our own sci- 
entific men, are attributed to those to whom he is indebted for 
them ; and the same just course is pursued in regard to many of 
the processes and experiments mentioned. 
The arrangement of the subjects in this edition is quite differ- 
ent from that which was followed in either of the former editions. 
It-is very nearly that of Turner; and a better model could not 
have been selected. The first chapter treats “of the Powers 
and Properties of Matter, and of the general laws of chemical 
changes ;” and in it are ineorporated the new facts relating to 
heat, electricity, and galvanism. The discoveries and deductions 
of Dr. Faraday are given principally from the lucid and satisfac- 
tory statements of Dr. Turner, some additions being made to the 
account from Faraday’s later papers. The very curious and in- 
teresting observations of Forbes, on the polarization of heat, are 
also referred to in this chapter. 
The second chapter is a highly important one, inasmuch as it 
contains the very alphabet of the science, without a knowledge 
of which every thing would be as unintelligible and as incompre- 
hensible as the alchemistic gibberish of former days; and also a 
full description of the apparatus to be used, and the manner of 
using it, without a familiarity with which, all previous knowledge 
would be of little practical advantage. This chapter is divided 
into three sections ; the first embracing an outline of the new 
nomenclature, with an explanation of the principles upon which 
it is founded ; the second, a detailed account of “ Apparatus and 
ipulation,” fully and clearly illustrated by explanatory cuts ;
