in Yale College.—An explanatory notice of this work, (then nearly 
finished,) was given in No. 2 of Vol. XIX of this Journal. The 
work is now completed, and is comprised within two octavo volumes, 
averaging a little over 600 pages, besides an appendix of 48, The 
figures (chiefly those of Dr. Hare,) are given in the pages in wood 
cuts, except that there are three distinct plates to illustrate Dr. Hare’s 
galvanic instruments. 
The principal discoveries and doctrines are brought down to the 
“present time, and there are also notices of American science ane arts, 
with many miscellaneous facts. © 
The principal object of this work is to present to the chemical stu- — 
dent a condensed digest of the subject, in such a form as to facilitate his 
progress; it contains also copious references to original authorities, 
many pharmaceutical processes and medical notices, and the neces- 
sary directions for the performance of experiments. 
Although this work was designed and executed in accordance 
with the wishes of former classes in Yale College, and is made 
companion of the experimental course there given, the students of 
that institution are left at liberty to use it or not as they choose, and 
it is easily adapted to any other course in which a different arrange 
ment of the subject is pursued, and in which it may be found useful.
