Albert Hopkins was born in Stockbridge, Mass., July 14, 1807, 

 and died in Williamstown, May 25, 1872. He graduated at Williams 

 College in 1826. In 1827 he was elected Tutor in the College, and 

 in 1829 was called to the Chair of Mathematics and Natural Philos- 

 ophy. He then visited Europe, mainly at his own expense, and pur- 

 chased apparatus for the College, — valuable and ample for those 

 times. After his return, in 1835, he built the Astronomical Observa- 

 tory for the College, mostly from his own means. In 1838 the title 

 of his chair was changed to that of " Natural Philosophy and Astron- 

 omy," and in 1869 he was made "Memorial Professor of Astronomy," 

 and relieved of all other duties. 



Sickness in his family, for many years, interfered with original 

 work, but for more than forty years he was a laborious and successful 

 officer of College. He not only kept alive an interest in his own 

 department by his faithful instruction, but in the early days of his 

 Professorship, in connection with Eaton and Emmons, he did much to 

 encourage study in the different departments of Natural History. 



* The biographical notice of Daniel Trearlwell, not having been prepared in 

 season to take its place in the Council's Eeport of last year, was to have been 

 appended to the present report. Meanwhile the Academy has invited Dr. 

 Morrill Wynian to prepare a fuller memoir of Mr. Treadwell, which will take 

 the place of the customary biographical sketch.
