M FLAMMARION, in the comprehensive report referred to below, not only gives a summary of the meteorological conditions in Paris during the years 1915 and 1916, but also carries the comparison of the seasonal variations of the principal climatic elements back to 1886: The year 1915 had a mean temperature equal to 10.4° C, or 0.2° above the normal, while 1916 was in even closer accordance with the average. The rainfall of 1915 was 574 mm., and of 1916 698 mm., or respectively 3 per cent, and 22 per cent, above the average. The author concludes that “in spite of the frightful intensity of the cannonades, they have exerted no influence on the rainfall in the region of Paris.” In 1915 less than half the average fell in the months of March, May, and October, the only month showing an excess being December, when, however, the rainfall was more than double the average. This was followed by a very dry January (1916), with less than a quarter of the average. Although somewhat wetter than 1915, ho month in 1916 had an excess of rain greater than one-third of the average.
