162 Miscellaneous Intelligence. 
Among the investigations proposed for the coming year are the 
measurement of the position of the principal lines in the spectra 
of all banded stars as yet known; also the photometric deter- 
mination of the brightness of various points on the surface of the 
moon; the measurement of the light of faint stars, for which a 
system of standards of brightness has been devised with the 
mspenition of other astronomers. The new Hema photometer 
will be used for measuring variable stars and their comparison 
stars, and also for determining the light of the bree asteroids.

tribes who erected the burial mounds in the Ohio valley and 
should regard as having been cast; on the contrary, the evi- 
dence of hes gre ae and rolling between stones, is more or less 
clearly shown in all by the character of the surface and by the 
distinct lero of the metal in places, when carefully exam-
