 time. The heaviest fall of snow was nine inches, which occurred on 

 December 6th, 1868. The following table shows the depth of snow 

 for each month of the five years :

to January 1, 1873. 



Another important element in climate is the 



WIND. 



The relative frequency of each of the eight directions of the wind 

 is given in the following table, which embodies 5481 observations. 

 The figures represent the number of times the wind blew from each 

 direction for each year :

to January 1st, 1873. 



It will be seen from this table that the south winds (including 

 southeast, south, and southwest winds) outnumber the north winds 

 (including northe ;st, north, and northwest winds) in the ratio of 434 

 to 370. At Marietta, Ohio, which is in nearly the same latitude as 

 Lawrence, the south winds also prevail, while at Brunswick, Maine, 

 on the contrary, the north winds outnumber the south winds in the 

 ratio of 503 to 417. In regard to the 



VELOCITY OF THE WIND, 



Our observations extend over the brief period of six months, from 

 July 1st to December 31st, 1872. During this time the anemometer 

 placed on the north dome of the University building registered
