Van Nostrand’s Chemical Annual, 1907. First Year of 
Issue. Edited by John C. Olsen, A. M., Ph. D. New York, 
D. Van Nostrand Co. x - 496 pp. The “Chemiker Kalendar” 
has long been a most useful publication but American chem- 
ists have desired a similar publication in English. In the 
new Annual Professor Olsen has improved upon the German 
model and produced an extremely satisfactory reference 
work. It consists exclusively of tables of physical and chem- 
ical data and lists of pnblications. The physical constants 
of inorganic and organic compounds are given in two tables, 
comprising nearly one half of the book. It is a pleasure to 
And frequently definite values for solubilities. The “Review 
of Chemical Literature” consists of a classified list of the 
more important articles published in the Journals and also a 
classified list of books, the time covered being from Jan. 1, 
1905 to June 1, 1906. It is cause for congratulation that 
Professor Olsen undertook the editorship of a book which is 
so indespensible to the chemist. The execution of the mech- 
anical part is excellent. A. S. W. 
Solubilities of Inorganic and Organic Substances. A 
hand-book of the most reliable quantitative solubility deter- 
minations. Recalculated and complied by Atherton Seidell. 
8vo X - 367 pp. D. Van Nostrand Company. New York, 
1907. The only dictionary of chemical solubilities has been 
Comey’s which was published in 1894. Although it is a book 
of great value there are several defects which detract from its 
usefulness. It contains no organic substances but we find 
instead a great variety of rare inorganic double salts. Too 
many unreliable determinations are incorporated and the 
arrangement is not consistent throughout so that it is fre-
