370 HISTORY OF ASTRONOMY. 



the comets of 1807, 1811, 1819, 1845, 1846, and 1847 ; 

 the solar eclipses of 1780, 1781, 1782, 1791, 1806, 1811, 

 1845, and 1846 ; various occupations of stars ; observa- 

 tions of nebulas ; and observations and computations for 

 the latitude and longitude of various places in the 

 United States. 



The Memoirs of the Connecticut Academy contain 

 observations of the comets of 1807 and 1811, by Mans- 

 field and Day, and the calculation of the longitude of 

 Yale Colleger 



The Transactions of the Albany Institute contain a 

 notice of the solar eclipse of 1806, by Simeon De Witt, 

 and observations of the solar eclipses of 1831 and 1832, 

 by Professor S. Alexander. 



The American Journal of Science contains some 

 original observations of comets and eclipses, and has 

 been the vehicle for the diffusion of much valuable in- 

 formation respecting subjects of passing interest. 



The American Almanac, which has been published 

 regularly since 1830, has given each year very full com- 

 putations of all visible eclipses, and the elements for the 

 calculation of occultations of stars by the moon. These 

 I computations were made by Mr. E. T. Paine until the 

 1 year 1841, and since that time by Professor Pierce and 

 \Mr. G. P. Bond. 



The United States Almanac, which only continued for 

 three years, gave, in addition to the usual astronomical 

 articles, a great variety of tables useful to computers. 



The computation of the occultations of all stars down
