116 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



PROPOSED CHART OF THE WEATHER. 



Captain Hoffmeyer, 'director of the Royal Meteorological 

 Institute of Copenhagen, announces his intention to publish 

 daily charts of the weather from 60 east to 60 west longi- 

 tude, and from 30 to 75 north latitude. The charts for the 

 three months from December to February will be published 

 as an experiment ; and the work will be continued should 

 suitable support be given. The cost will be four francs per 

 month, exclusive of postal charges. 12 A , June 25, 1874,

METEOROLOGY IN JAPAN. 



At a recent meeting of the Asiatic Society of Japan it was 

 stated that the Army Signal-office had expressed its willing- 

 ness to assist the society, in any possible way, to secure a 

 complete set of meteorological observations in Yokohama; 

 that, on the other hand, the assistance of the Japanese gov- 

 ernment was much to be desired, in order that a general sys- 

 tem of meteorological reports might be made throughout the 

 empire, in accordance with the simultaneous system recom- 

 mended at Vienna. The light-house and mining departments 

 of Japan keep meteorological records, and it was remarked by 

 Professor Ayrton that the Japanese government, so far as he 

 was able to learn, was inclined to leave purely astronomical 

 observations to the Naval Department, while the Engineer- 

 ings College would undertake those of a meteorological char- 

 acter. Men eminently adapted to the most accurate obser- 

 vations could, according to him, be readily found among the 

 cultivated Japanese. The importance of telegraphic lines 

 and telegraphic communication in Japan, in reference to 

 earthquakes, was especially mentioned, and also the interest 

 that would attach to electrical observations. Japan Weekly

DIFFERENCE OF TEMPERATURE BETWEEN THE COUNTRY AND 



CITY. 



This difference has been investigated by Fines, who finds 

 that, as has been also generally ascertained by other obser- 

 vations, the mean annual temperature in the interior of a 

 city is decidedly higher than outside. On the other hand,
