rom the several Secretaries, and may not € quite correct in all 
respects, although -it is believed that it contains all the subjects 
discussed, relating properly to science. | 
We are at present able to present only: a few authentic abstracts 
of the several papers, and these are confined to the physical sec~

the papers will, no doubt, appear in full from time to time in our 
pages—as is true of Prof. Shepard’s Teper on meteorites, in our 
present number.
