Lieut. ANTHONY W. VocDEs, U. S. A., was elected a Corre- 
sponding Member. 
The PRESIDENT reported his receipt of a request from the Am- 
erican Museum of Natural History, for the removal of the Botani 
cal Collections belonging to the Academy, and stated that they 
would be brought down and stored with the Annals in the build- 
ing of Columbia College. 
He exhibited a series of photographs of the ruins and desolation 
produced by the recent earthquakes in Ischia; also, an egg of the 
alligator from Florida, showing the young animal just protruding 
its head from the shell, with the end of the tail beside the jaws; 
also, a portion of a placoderm fossil fish from the Chemung of 
Pennsylvania, described by Prof. CLAypoLr, under the name of 
Pterichthys corrugatus. 
Prof. FREDERICK STENGEL had translated, at the request of the 
Academy, and now read, a paper by Prof. F. Firrica, of the Uni- 
versity of Marburg, (published in the Annals, vol. III.) 
UPON A FOURTH MONOBROMPHENOLE. 
DISCUSSION. 
Prof. A. R. LEEDS considered these statements of the author of very 
great importance. He described the constitution of the benzole-ring 
of Kekulé, and stated that he did not see the potency of the a priori 
reasoning of Prof. FITTICA, nor any evidence of the existence of the 
monobromphenole—that he had really produced such a compound. 
The difficulties attending the solution of this question were much 
greater than might be supposed, to satisfactorily determine its differ- 
ence from the other compounds of bromine and phenole. 
Dr. B. N. MARTIN then called the attention of the Academy to the 
peculiar phenomena recently occurring in connection with the sunsets, 
and described the brilliant crimson colors which affected the western 
sky before and after the disappearance of the sun. 
Prof. O. P. HUBBARD had observed in the morning also, at about 
6 o’clock, that the entire heavens had been dyed in the same brilliant 
colors from west to southeast for half an hour. He also referred toa 
similar phenomenon on August 20, 1831. An insurrection was then in 
preparation among the slaves in Virginia, where he was at that time. 
Its leader had arranged for the outbreak on a particular day, somewhat 
later than the day mentioned, but the remarkable appearance of the 
sky induced him to begin it prematurely at that time. Among other 
phenomena, the sun assumed a decided green color every afternoon
