1. Location of Lick Observatory on Mount Hamilton, Cali- 
fornia.—In a report to the Trustees of the James Lick trust, Mr. 
S. W. Burnham gives the results of his observations made on Mt. 
Hamilton as to the location of the Lick Observatory. Mt. Hamil- 
ton is situated nearly east from San José, about twenty-six miles 
by the highway, but only thirteen in an air line. e approxi- 
surrounding ridges, is of trap rock.” Mr. Burnham’s astronomical 
observations here reported had regard especially to the atmos- 
pheric conditions of the location with reference to its adaptation 
to Prashegetl purposes. He states in his concluding remarks:

observations were made, there can be no doubt that Mt. Hamilton 
offers advantages superior to those found at any point where a

made is a matter of no small importance, particularly in connec- 
difficult objects can be seen almost down to the horizon will be 
apparent from the southern declination of many of the new double 
stars. Close pairs can be observed at least down to 43° South 
Declination. The permanent steadiness of the air during the 
mer of the present year shows that the good seeing very rarely 
continued the whole night, even when it remained clear, and this 
other day, and, as already shown, the same statement would apply 
equally well to the nights. Apparently there is but little to be
