the center of low pressure is nearly 400 miles; they are gener- 
ally on the east side of the low center, and are most frequently 
found nearly in the direction of the average progress of storm 
tracks. ‘There is, then, an intimate connection between the rain- 
ical influences, I have prepared tables showing for a series of 
years the principal rain-falls in Europe. I selected from the 
Balletin of International Meteorological Observations all those 
cases in which a rain-fall of two inches in twenty-four hours was 
reported at any station during the years 1878, 9 and 80. These 
cases are 233 in number, and the stations at which more than 
three cases of these great rain-falls occurred are shown in the 
following table. Column 2d shows the latitude of the station;

column 38d its elevation in feet above the sea, and column 
4th the number of cases in which a rain-fall of two inches 
tenths of a millimeter, but was reported in such a way that 
the numbers were understood to represent millimeters, thus 
making the rain-fall ten times too great. Of the other thirteen 
stations, all but one are in the south of Europe, and show un- 
equivocaliy the influence of local causes; two of the stations 
ing on mountains and the others being in the neighborhood 
of mountains where the mean annual rain-fall is unusually 
great.
