CIRCULAR. 



PHILADELPHIA, June llth, 1836. 



109. The Joint Committee " on Meteorology," appointed 

 by the American Philosophical Society and the Franklin 

 Institute of the State of Pennsylvania for the Promotion of the 

 Mechanic Arts, being very desirous of ascertaining the boun- 

 daries of the great storms which traverse the United States, 

 and the direction of the wind in those boundaries; take the 

 liberty of requesting you to inform them when the rain be- 

 gan arid ended at your place ; in what direction the wind 

 blew during the rain, and, if possible, how and when it 

 changed ; whether it was violent or gentle, and whether 

 there was much or little rain. These questions relate par- 

 ticularly to the great rain at the end of May and beginning 

 of June. But if the same questions should be answered as 

 to all the storms which may occur within the next twelve 

 months, by all to whom this circular is sent, the result can- 

 not but be highly interesting. 



This storm, which has been so general on our seaboard, 

 began at Philadelphia on the 26th of May, at half past seven, 

 P. M. and ended on the sixth of June, at three, P. M.
