An Important New Book in Climatology 



The Weather and Climate of Chicago. By HENRY J. COX, Professor of Meteorology, United 

 States Weather Bureau, and JOHN H. ARMINGTON, Local Forecaster. (BuUetin No. 4, Geo- 

 graphic Society of Chicago.) 



The importance of this book is indicated by the fact it is issued under the auspices of the Geographic 

 Society of Chicago, and has been prepared by two of the best known weather experts in the country. 

 It includes discussions of a great variety of subjects such as temperature, precipitation, atmospheric 

 moisture, cloudiness and sunshine, wind direction and velocity, barometric pressure, and storm tracks ; 

 and among the interesting appendixes to the book are one on the weather of holidays and another con- 

 taining journal entries relative to the Chicago fire of 1871. The book contains also a remarkable series 

 of tables with reference to temperature, precipitation, atmospheric moisture, and atmospheric pressure — 

 one hundred and forty-seven in all, with more than one hundred figures and plates. 



The volume, because of its character and authority, will be of great general interest, as well as of 

 especial significance to students of climatology and geography. 



396 pages, 8vo, cloth, $3.00, postage extra. (Weight, 49 oz.) 



Of special interest to teachers in connection with The Weather and Climate of Chicago is
