All scientists of the Bay Area interested in the advancement
of MICROSCOPY and PHOTOMICROGRAPHY are cordially invited to meet
in the Auditorium of the San Francisco Health Department, 101 Grove
Street, Civic Center, San Francisco, California, on Friday evening,
October 4th, 1946, at 8 P.M. to organize and elect officers for the
SAN FRANCISCO MICROSCOPICAL SOCIETY.

     One of the first microscopical societies in the United States
was organized in San Francisco on June 4th, 1870, and incorporated
in 1872 as the San Francisco Microscopical Society.  This organiza-
tion had a very successful existence for more than a third of a cent-
ury, disbanding after the Fire of 1906.  The Society had its own
rooms in downtown San Francisco for many years with microscopes, a
photomicrographic optical bench, dark room, slide collection and
library available to the members.  The membership included many prom-
inent microscopists: Dr. J. H. Wythe, author of a standard book on the
microscope, Professor Frank T. Green, Toxicologist for the City of
San Francisco for many years, Dr. Gustav Eisen, later of Columbia
University, New York, Mr. E. W. Runyon, Dr. Sallard of Palo Alto, and
many others.  After a lapse of forty years, the formation of a new
Society to carry on the high ideals of the original organization is a
most worthy effort and deserving of the full support of all serious
workers with the microscope.

     Following the above business meeting, Mr. George H. Needham,
past President of the New York Microscopical Society and Fellow of
the Royal Microscopical Society of London, will show 2x2" KODACHROME
and ANSCO COLOR PHOTOMICROGRAPHS taken with Transmitted, Dark Field
and Polarized Light.
