Acknowledgments to Correspondents. 
A letter addressed to the editor, from Key West, under date of 
August 14, 1836, by Lt. Benj. Alvord, of the army, mentions Elli- 
cott’s account, as published in his journal, of the meteors, which ap- 
peared near the Florida Reef, on the night of the 12th and 13th of 
of Nov. 1796. A copy of the Boston Columbian Centinel, dated 
May 14, 1803, forwarded to the editor by Mr. A. Shearman, con- 
tains an interesting notice of a great shower of meteors at Richmond, 
in Virginia, a little before the date named above. These communi- 
cations were handed to Prof. Olmsted, of Yale College, who is well 
known as an ardent and successful investigator of the phenomena of 
meteors, and he assures us that the facts alluded to-above, were be- 
fore known to him, and have been cited in the accounts already pub- 
lished. 
Several communications intended for this number, came too late, 
and many more are in hand; most of them will be inserted, but 
perhaps not without some delay.
