NETWORK ACADEMY OF SCIENCES
The Royal Society holds five soirees in London
every winter for the promotion OF science in three
ways-the exhibition OF new apparatus and speci-
mems. short lectures demonstrations and social
converse between workers who do not often meet
at any other time. The New-York Academy of
Sciences has for six years been following a some
what similar plan. 1t holds but one such ex-
hbiton year-usually in the spring. But II pro-
vides for more extensive and comprehensive dis
play OF new things than does the famous British
organization referred II proongs the affair so
as TO have two evening receptions and IT opens its
exhibition 10 limited part of the public for an
afternoon. II has tried the experiment of lectures
in connection with the receptions but has decided
that better results be secured by the omission
