ed. The isothermal charts present many of the defects com- 

 mon to all similar charts published so far. The isothermals 

 for the months of January and July are the only ones that 

 have as yet been accurately worked, out for the whole globe. 

 These charts place it beyond all doubt that it is to the winds 

 that we must now look as the prime mover of oceanic cur- 

 rents. 12 A, IX., 288. 



MARITIME METEOROLOGY. 



The Meteorological Congress at Vienna expressed its con- 

 viction that it was desirable that each country should, if pos- 

 sible, collect all its meteorological observations at one place ; 

 that the Institute for Maritime Meteorology should, be estab- 

 lished as near as possible to the sea, and that this institute 

 might best be placed under the general management of the 

 chief meteorological institute of the country. The convening 

 of a Maritime Meteorological Conference was declared to be 

 desirable, and a permanent committee appointed with this 

 end in view. 12 A, X., 18. 



METEOROLOGY IX YOKOHAMA. 



The German branch at Yokohama of the Society for the 

 Natural History and Ethnology of Eastern Asia shows in its 

 last publication the activity of its members. Besides regu- 

 lar meteorological observations taken apparently under the 

 auspices of the society, and published by them, we have very 

 numerous determinations of altitudes in Japan, by means, of 

 course, of the portable barometer, and have also some excel- 

 lent descriptions of the volcano of Fusiyama. The first ac- 

 curate measurement of the altitude of that volcano appears 

 to be due to the members of this society ; especially to Knip- 

 ping, who seems to have made a series of observations for 

 fourteen days, five times daily, at very carefully selected 

 hours ; simultaneous observations were made at three points, 

 namely, the summit, the base, and intermediate stations. 

 The best standard instruments by Green and other makers 

 were used, and the computations were made by the formula 

 lately published by Riihlmann, and which has met with so 

 much acceptance. The resulting altitude of the summit of 

 Fusiyama 12,235 feet places it among the loftiest of vol- 

 canoes. jSLiUheilungen, Yokohama.
