N. B. In William's History of Vermont, (which I read many 

 years ago,) I think there are several statements respecting the dis- 

 covery of Jive frogs at great depths.

10. On the occult ation of Aldebaran, in a letter to the Editor, 

 dated July 24, 1830; from J. Thompson, Prof Math, in Nashville 

 Univ. (Tenn.) — In order to obtain the difference of longitude accu- 

 rately between different places, it has been frequently recommended 

 to compare corresponding observations of occultations, lunar trans- 

 its, &c. made under the meridians of those places whose longitudes 

 are required, the result of which would be free from the errors of 

 the tables. But although the method recommended offers obvious 

 advantages, few are enabled to avail themselves of the results of 

 observations made by others, as no concerted plan has been adopted 



by astronomers in this country of making their observations general- 

 ly known. 



In the American Almanac on the subject of occultations, the fol- 

 lowing particulars are proposed for observation at the time of an ob- 

 served occultation. 



1 • Whether the star undergoes any change of light, of color, or of 

 motion, on its immediate approach to the edge of the moon.
