tcor at New Haven, in which it was stated, that the observed azimuth, 

 at the time of* its disappearance, was 68°, and its altitude 11°. 



From these elements, it resulted, that the meteor, when it disap- 

 peared, must have been 223.35 English miles distant from New 

 Haven; and 131.73 from Princeton. The perpendicular altitude de- 

 duced from the New Haven observation, was 48.71 miles; from that 

 at Princeton, 65.79 miles. The diameter of the meteor, from the ob- 

 servation at the latter place, was 0.4598 of a mile. 



Prof. Alexander remarked, in conclusion, that these results, in so 

 far as they admitted of a comparison, did not accord very well ; and 

 that accounts of other observations were desirable. 



Professor Henry mentioned, that he had recently repeated 

 some experiments of Becquerel and Biot on phosphorescence, 

 the results of which demonstrate the existence of an emanation 

 from incandescent bodies, particularly when in an electrical 

 state, of a character not heretofore known. He promised to 

 give a more full account of these at a future meeting of the 

 Society.
