LABORS OF THE JOINT COMMITTEE.

 Society and the Franklin Institute to unite in forming a 

 Joint Committee on the subject ; and their principal labors 

 are given below. 



CIRCULAR. 



PHILADELPHIA, Sept. 1834. 



SIR, At a joint meeting of two committees appointed, 

 one by the American Philosophical Society, and one by the 

 Committee of Science and the Arts of the Franklin Institute 

 of the State of Pennsylvania, to confer together on the best 

 means of promoting the advancement of Meteorology, held 

 at the hall of the Franklin Institute, on the evening of the 

 9th inst, it was resolved that a sub-committee be appointed 

 to furnish a project for certain simple observations, which 

 may tend to elucidate important points in Meteorology, and 

 which may be at once entered upon, by observers in differ- 

 ent parts of our country, and also to present a form of cir- 

 cular, to be forwarded to persons who may be considered 

 competent to carry into effect the above objects. 



In conformity with this resolution, and as a preliminary 

 to the introduction of a more extended plan, which the joint 

 committees are now maturing, the following circular has 

 been prepared, and is forwarded to you by the committee.
