the highest points, the Slide mountain reaching 4205 feet above 
tide water, and the Panther 3828. The region is an almost 
unbroken forest in spite of its proximity to the great centers of

Microscopy at THE AMERICAN ASSOCIATION.— There is reason

his is a great improvement on the original offer.

news. The editor's address is P. O. Box 3838, New York.
