logical theories, but who have nor been able to keep informed 

 concerning the appearance of new foreign articles on the Bub 

 ject. A> there arc bo many papers to be mentioned, I have 

 merely endeavored to give a general idea of the nature of each 

 one, and have indicated the attitude of the writers toward 



meteorology bv a slight reference to other work done in tins 

 same direction. It" I had attempted to give an account of the 

 methods and results of each one, not more than two, or possi- 

 bly three, of the fourteen papers mentioned here could have 

 been reviewed within the limits of this article; and that would 

 not have shown so clearly as I wished to bring out, the renewal 

 of interest which is taking place concerning progress in the 

 theoretical development of meteorology. Special attention is 

 called to the lack of interest shown on this subject by English 

 and American physicists; at least if we are to judge or the 

 interest by the number of contributions relating to it.
