From which he concludes that the latitude is 41° 14’ 37” nearly. 
- The paper contains a series of fifty moon culminations, one eclipse, 
and six occultations, observed in 1838 and 1839. These furnish data 
for determining the longitude of the Hudson Observatory when cor- 
responding European and American observations shall have been ob- 
tained. Prof. Loomis gives for the approximate longitude 5h. 25m. 
42s. It may be proper to add, that one of the undersigned, 8. C. 
Walker, having reduced the six occultations contained in this paper, 
and compared them with four corresponding observations at the Phil- 
adelphia Observatory, four at the Dorchester Observatory, two at Mr. 
Paine’s House, Boston, and one at Princeton College, New Jersey, 
finds for the longitude of the Hudson Observatory 5h. 25m. 47s. 
The instruments for this observatory were selected by Professor 
Loomis during his late journey in Europe. This economical estab- 
lishment appears to be more complete than any of the kind now 
known to be in operation in the United States, and the Committee 
cordially recommend the example of the Western Reserve College, as 
worthy of being followed by those universities which are desirous at 
moderate expense, of inculcating practical astronomy, of making ob- 
servations highly useful for geographical purposes, and of prosecu- 
ting interesting researches = with te progress and advance- 
ment of astronomy.

Dr, Bache, on behalf of the Committee on Dr. Hare’s paper enti- 
tled **On the extrication of Barium, Strontium and Calcium,” report- 
ed in favor of publication in the Society’s Transactions, which was 
ordered accordingly. 
In this paper Dr. Hare first calls attention to the following phe- 
nomenon observed by him almost twelve years since, and published. 
When the circuit in a galvanic battery, the deflagrator of the author,
