The variation in the minimum monthly value (if there is any variation at 
all) cannot be well determined from the Tables. 
Ireland.—The returns from Ireland are still fewer than those from Scot- 
land, and the range in the values of the mean annual falls is very limited. 
Still the prevalence of a slight summer maximum and February minimum at 
the station with little rain, but a winter maximum and May minimum at 
those with little rain is traceable—though with far less distinctness than the 
corresponding extremes in either the Scotch or English tabulations. The 
following diagram (fig. 6) gives the “‘ 20 to 25-in.” and “ 35 to 40-in.” curves 
for the period 1850-59. 
To recapitulate brietly, we find that in England and Wales the following 
rules are generally observed in the distribution of rain during the different 
months of the year :— 
* « First.—If we take an average of a considerable number of years of the 
rainfall at various stations, we find that not only do the mean annual amounts 
vary, but the monthly percentages of those amounts also vary considerably.
