3. Cambridge Observatory.—The deficiency of instruments at this 
observatory is about to be supplied upon a scale of munificence, worthy 
of. the princely liberality of the Boston merchants. Davin Sears of 
Boston has given five thousand dollars for the erection of an observato- 
ry tower, which will be furnished with instruments from a contribution 
of twenty thousand dollars, which was subscribed within sixty days from 
the date of the Sears donation, and to which he himself gave an addi- 
tional sum of five hundred dollars. The ready patronage, which has, 
upon this occasion, been so generously extended to American astrono- 
my, is most honorable to the republic, and no country can point toa 
larger donation to science, in proportion to its wealth. The other do- 
nors are Peter C. Brooks, who gave one thousand dollars; Samuel Ap- 
pleton, William Appleton, John P. Cushing of Watertown, Joseph Pea- 
body of Salem, Thomas H. Perkins, Jonathan Phillips, Robert G. Shaw,
