Column 4 shows the height of the statious in English feet, and eolnnin .5 shows the number 

 of years of observaiioii employed. Tlie numbers given for each mouth represeut the meau daily 

 movement of the wind in English miles. At the bottom of each group of stations is giv^en the 

 mean of the numbers in each column of that grouj) ; the tbllo^v^ing line gives the average of the 

 numbers in the two groups; tlie next line shows the velocity of the wind expressed in miles per 

 hour ; the next line shows the average rate of progress of the cyclones recorded in Tables VII and 

 IX for each month in which more than one cyclone was observed, and the last line shows the 

 ratio of the numbers in the two jtreceding lines. 



Here we find no correspondence between the average rate of progress of storm centers for the 

 different months of the year and the average velocity of the wind, the rate of progress of storms 

 being no greater for the four months in which the wind was s rongest than for the four months 

 in which the wind was feeblest. The iueipiality in the values of the ratio for the difterent months 

 is quite noticeable, but this may be partly due to the small number of the observations. 



94. I next endeavored to determine the mean velocity of the wind in the neighborhood of 

 the West India Islands, but found very Uiw ol)servations suited to this purpose. Tal)Ie XXXIX 

 shows all the materials I have been able to obtuin. The numbers for the first four stations are 

 derived from the Signal Service ob.servations, the numbers for the last two stations are derived 

 from the international observations, and the numbers for Havana are derived partly from the 

 international observations and partly from observations at the observatory of St, Beleu,
