NUMBER of useful meteorological memoirs by Prof. Eredia, of the Central Meteorological and Geophysical Institute of Rome, deal with various aspects of the meteorology of Italy. No. 1 is the Italian meteorological observers' handbook, copiously illustrated, in which full instructions are given regard ing the installation of instruments for a normal station, along with practical hints regarding its main tenance. Instructions are also given for the taking of phenological observations. “The Variation of the Climate in Italy” (No. 2) is a reprint of a paper read at the tenth International Geographical Congress held in Rome during 1913, in which the mean annual tempera ture from 1866 to 1910 at sixteen stations is discussed, The warmest year was 1879, except in the insular areas, while 1900 was the coldest. The temperature variations, it may be said, are in general the reverse of those in the British Isles. Fog frequency over theregion embraced by Lombardy, Venetia, and Emilia, based on data for twenty-three stations over the period 1892—1914, forms the subject-matter of No. 3. From May to August there are few fogs, the maximum taking place in winter Maps of fog frequency are given for the autumn, winter, and for the year, while several isobaric charts indicate the conditions associated with some winter fogs.
