of the year ia Europe is ouly about half as great as in the United States. The inequalities in the 

 value of the ratio for the different months are considerable, and indicate thQ operation of some 

 other cau.se than the mean velocity of the wind. 



93. I next determined, as well as I was able with the means at my command, the average 

 velocity of the wind in the neighborhood of the Bay of Bengal and China Sea. Table XXXVIII 

 shows the results which I have obtained, the observations being all derived from the Report on 

 the Meteorology of India for 1882, with the exception of Manilla, which is derived from the 

 international ob.servations. I hiive employed only stations south of latitude 20°, an.d I have 

 rejected all stations having an elevation greater than 3,000 feet.
