continuation southward of Argelander's and Schonfeld's work. 

 It is to be followed by a second volume during this year, and an 

 atlas of twelve plates. The two volumes and the atlas will cover 

 the belt from 22° to 42° south declination, and will represent 

 the result of 1,108,600 observations made by Mr. Thome and Mr. 

 Tucker. The star-places are for the epoch 1875.0. 



3. Smithsonian Meteorological Tables (based on Guyot's 

 Meteorological and Physical Tables). 262 pp. 8vo. Washing- 

 ton, 1893. — (Smithsonian Miscellaneous Contributions, vol. xxxv, 

 No. 884.) The fourth edition of Guyot's invaluable Tables was 

 published in 1884 not long after the death of the lamented author; 

 the completion of the work being performed by his assistant, 

 Prof. Wm. Libbey. The present volume is one of three which, as 

 stated by Professor Langley, are to supply the place of a fifth 

 edition of these tables ; the three parts into which the subject is 

 to be divided being Meteorological, Geographical and Physical. 

 Tables based upon the value of the meter provisionally assumed 

 by the U. S. Coast and Geodetic Survey, (viz : 1 meter = 39*3700 

 inches, have been made by Mr. George E. Curtis. He has also 

 prepared the entire manuscript and carried the work through the 

 press, and to him therefore the many who will use it are deeply 

 indebted. There are one hundred tables included, thermometrical, 

 barometrical, hygrometrical, etc., and these are preceded by 

 about fifty pages of text descriptive of their use.
