HANDBOOK Of METEOROLOGICAL TABLES. 



By Asst. Peof. H. A. Hazen. 

 127 pp. 8°. 



A collection of all the tables needed by a 

 working meteorologist. 'Several of these 

 tables have never been printed before. 



Professor Waldo says : "I heartily recom- 

 mend them to all workers in meteorology, 

 and do not see how any of our American 

 meteorologists can afford to be without a 

 copy." 



Professor Symons of London says ; ' ' They 

 are unquestionably valuable helps, which 

 must be kept handy, and replaced when 

 worn out."
