14. Elements of Chemistry, in the order of the lectures given 

 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 and 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 the 

 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.
