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 

 corresponding European and American observations shall have been 

 obtained. Prof. Loomis gives for the approximate longitude bh 25m 

 4.2s. It may be proper to add, that one of the undersigned, S. C. 

 Walker, having reduced the six occultations contained in this paper, 

 and compared them with four corresponding observations at the 

 Philadelphia 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 

 observations highly useful for geographical purposes, and of prose- 

 cuting interesting researches connected with the progress and advance- 

 ment of astronomy. 



The Committee recommend the paper for publication.

The recommendation in favour of publication, was adopted. 



Dr. Bache, on behalf of the Committee on Dr. Hare's paper, 

 entitled "On the extrication of Barium, Strontium and Cal- 

 cium," reported in favour of publication in the Society's 

 Transactions, which was ordered accordingly. 



In this paper Dr. Hai*e first calls attention to the following pheno- 

 menon observed by him almost twelve years since, and published.
