Medical Microscopical Society. 
The Annual General Meeting of this Society was held on Friday, 
January 15, at the Royal Westminster Ophthalmic Hospital, Jabez 
Hogg, Esq., the retiring President, in the chair. 
From the report of the Committee it appeared that the Society 
was in a flourishing condition ; the number of members being 135. 
The number of papers read during the past year was sixteen, besides 
several minor communications, all of which were followed by brisk 
discussions. Above 100 specimens were exhibited during the year, 
and eighteen were presented to the Society. A present was also 
announced of a microscope for use in the exchange of specimens ; a 
system which is found to work well, and offers great facilities for 
obtaining a large collection of good preparations. The Treasurer's 
Report showed a balance of 15Z. 10s.

QuEKETT Microscopical Club. 
Ordinary Meeting, January 22, 1875.— Dr. Matthews, F.R.M.S., 
President, in the chair. 
Mr. T. Charters White, F.R.M.S., read a paper on " The Aquarium 
as a field of Microscopical Research." 
The author commenced his paper by regretting that the aquarium 
was not more largely employed as an aid to the observation of aquatic 
life ; and after pointing out the various life histories that might be 
worked out and the developmental phases of which accurately re- 
corded, proceeded to describe the simple arrangements necessary to the 
successful maintenance of a marine aquarium. The most convenient 
form of aquarium for microscopical observation was of an oblong 
shape, 36 inches long, 18 wide, and 9 in depth, and constructed of 
slate, with the exception of the front, which was of stout plate glassy 
a false bottom of slate, inclined from the front upwards and backwards 
at an angle of about 15°, so as to afford a varying depth of water, the 
water below it being kept cool and in the dark, and consequently at 
rest, while that above was exposed to the light, and actively ministering 
to the growth of the animal and vegetable life contained in it : roughly 
disposed on the false bottom, and cemented there by Portland cement,
