✦ Synopsis

Sixty members and visitors were present.

The meeting was called to order at eight o'clock. The minutes of the previous meeting were approved as recorded.

Dr. Henry Leffmann presented a communication on " Organic and Inorganic Forms Shown with the Projection Microscope." This very interesting lecture was illustrated by nine microscopic slides of vegetable organic forms including sections of seeds, leaves, roots, etc. Eight slides showing animal forms including mosquito and larva, head of tapeworm, proboscis of moth, etc. Also ten slides of rock sections and other inorganic forms shown by polarized light.

After some general discussion upon the habits and possible extermination of the mosquito from the New Jersey coast, the meeting adjourned at 9 o'clock.
