138 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



rian Lloyd Service in which special attention is, of course, 

 given to the law of storms, and which shows a very general 

 appreciation of the most recent works on this subject. 



A little volume has been published, at the price of one Eng- 

 lish shilling, by Hoveste & Sons, London, entitled " Weather 

 Warnings for Watchers, bv the Clerk of the Weather." The 

 book is mostly occupied with the details of instruments. 



A series of articles on meteorological topics, by Captain 

 Ansart, have appeared in occasional numbers of the Revue 

 Maritime et Goloniale during 1874, 1875, and 187G. In these 

 many new ideas and formulae are propounded which are not 

 likely to be generally accepted ; and yet the work will repay 

 attention. 



Rev. Samuel Haughton communicates to the Royal Socie- 

 ty of Dublin a geological proof, based on the examination of 

 the fossils found in the earth, that the changes of climate in 

 past times were not due to changes in the position of the 

 earth's axis, and gives as the lower limit to the duration of 

 geological time a minimum of 200,000,000 of years. 



Dr. Woeikoff exhibited in the Russian section of the Paris 

 Exposition a series of maps of isobars, isotherms, rainfall, etc., 

 for the globe; and the "text explanatory," which has been 

 widely distributed, shows that these charts, drawn from the 

 best sources, are, in general, an improvement upon those pro- 

 duced by Buchan, Wild, Buys-Ballot, Coffin, Schott, etc. 



On the climate, especially the temperature, of the United 

 States, Woeikoff has published in the Austrian JSIeteorolo- 

 r/ische Zeitschrift an extended review, basing his tables and 

 figures partially on the publications of the Smithsonian, Army 

 Engineers', Army Signal-Office, New York and Canadian Me- 

 teorological reports, etc. 



As a question of climatology, nothing can be more inter- 

 esting than the fluctuations of Great Salt Lake, as these are 

 now brought to light by the labors of Mr. Gilbert. It is to 

 be hoped that he will also investigate some of the other 

 lakes of the Rocky Mountain region, in order to eliminate 

 the influences of purely local circumstances. Great Salt 

 Lake was low from 1847 to 1850, w T as 5 feet higher in 1855, 

 but again as low as before in 1801 and 18G2 ; from 18C8 

 to 1S77 it has averaged about 10 feet higher than in 1850.
