Europe within which storm centers are most frequently found, 

 viz: between the parallels of 50 and 60 degrees. The follow- 

 ing table shows the results which I have obtained, and the 

 observations are divided into two groups as in the preceding 

 table; the coast stations being twelve in number, and the inland 

 stations bein^ fourteen in number. The velocities are all ex- 

 pressed in miles per hour.

The ratios of the velocities of storm centers to the mean veloci- 

 ties of the wind, are quite different from those found for the 

 United States, and the correspondence between the rate of 

 storm movements and the movement of the wind is not as dis- 

 tinctly marked. Nevertheless some degree of correspondence 

 can be detected, and it is noticeable that in Europe the change 

 in the wind's mean velocity for the different months of the 

 year is only 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 the operation of some other cause 

 than the mean velocity of the wind. 



I next determined the average velocity of the wind in the 

 neighborhood of the Bay of Bengal and China Sea. The fol- 

 lowing table shows the results which I have obtained, the obser- 

 vations being mostly derived from the Eeport on the Meteorol- 

 ogy of India for 1882. I have employed only stations south of 

 lat. 20° and I have rejected all stations having an elevation 

 greater than 3000 feet.

The number of coast stations is 17, and the number of 

 inland stations is also 17. The velocities are all expressed in 

 miles per hour. The ratios of the velocities of storm centers 

 to the mean velocities of the wind differ sensibly from those 

 found for Europe, and differ very greatly from those found in
