TWO more contributions by Prof. F. Eredia to our knowledge of the climate of Italy have recently appeared, one dealing with the normal mean values of annual rainfall in Italy, and the other with diurnal temperature variation in Sicily. In the first paper, “Le Medie normal! della quantita' di Pioggia in Italia” (Giornale del Genio Civile, anno lvi., 1918), the mean values for each calendar month are shown for nine well-distributed cities on the basis of the fifty-year period 1866–1915; and it is calculated that the values are correct to within 5 mm. for the rainier winter months and 9 mm. to 12 mm. for the summer months of smaller rainfall and more irregular distribution. In northern or continental Italy, as exemplified by Milan and Turin, the seasonal variation of rainfall is not prominent, but the wettest periods are early summer and autumn, the highest figures being for May and October. In peninsular Italy the typical Mediterranean feature of wet winters and dry summers is conspicuous, especially in the extreme south. Thus at Palermo the figure for December, the wettest month, is 108 mm. (4.3 in.), and for July, the driest, only 7 mm. (0.28 in.). The wettest city quoted is Genoa, on the Ligurian coast, where the wettest month, October, has 190 mm. (7.6 in.), and the driest, July, 47 mm. (1.9 in.); and here also the winter, as a whole, is considerably rainier than the summer.
