Hence it appears, that March is less fatal at the Hague and Haagambagt 

 than April, and April than May and June; that May is the most fatal month 

 of all; that the remaining months are nearly equal. It appears further, that 

 3 parts or seasons of the year, are very nearly equal ; but that the other quarter 

 or season, beginning at the vernal equinox, is more fatal than any of the rest 

 by a 15th part.
