Scientific Association, accompanied by numerous maps and diagrams. 

 His communication elicited great interest, and, after its reading, was dis 

 cussed by some of tiie most eminent inen in the grand Scientific Con_ 

 gress, among wliom were Professors Forbes and Phillips, and Sir David 

 Brewster. 



Mr. Espy also visited Paris, and communicated his views to the French 

 Academy, by which a committee was appointed to report upon the sub- 

 ject, consisting of Messrs. Arago, Pouillet, and Babinet. A report was 

 made at considerable length, containing a beautiful analysis of Mr. Espy's 

 theory, with conclusions extremely flattering to our countryman. This, 

 with the paper read before the British Association, may be found in Mr. 

 Espy's treatise on the Philosophy of Storms — a work which contains 

 much of the information collected by the " Joint Committee" in a con- 

 densed form. 



I cannot conclude this communication without expressing my opinion, 

 that a strong and very effective impulse was given to meteorological in- 

 vestigations at home and abroad by the combined efforts of this Society 

 and its associate, in organizing that system of simultaneous meteoro- 

 logical observations which has since been spread over the European con- 

 tinent, and is now resumed in our own country under the most favorable 

 conditions. 



In claiming for our Society the credit fairly due for its efforts formerly 

 made in the cause of meteorology, I do not wish to derogate from the 

 just claims of other institutions or individuals who have been working 

 earnestly in the same field of philosophical research. Any proper notice 

 of even one of these— the Smithsonian Institute, for example — would 

 lead me beyond the just limits of a communication adajjted to the usual 

 order of business established by this Society.
