these eggs, all laid by the same insect, he reared specimens of all the

Meeting of 20th March 1895, at 20 Hanover Square, W. 
The President (A. D. Michael, Esq., F.L.S.) in the Chair. 
The Minutes of the Meeting of 20th February last were read and 
confirmed, and were signed by the President. 
Prof. F. Jeffrey Bell said that their list of donations that evening 
consisted of two negatives and three stereoscopic photomicrographs of 
the gizzard of the house cricket, presented by the Hon. A. A. Adee 
of Washington, which were accompanied by the following explanation 
from Messrs. Watson : — 
“ The photograph is taken by means of an accurately adjusted tilting 
stage. The angle of this tilt must be varied to suit the angular aperture 
of the objective. The angle subtended by normal 10-in. vision is ex- 
aggerated fourfold by an objective of 60° angular aperture. The subject 
herewith was tilted only about 3f°. 
Mr. Adee says in his letter, ‘ I should be much gratified if you would 
cause a good print and the paired negatives to be presented to the 
Royal Microscopical Society at their next convenient meeting, in order 
that the discussion initiated by Dr. Borden’s announcement and its 
results in his hands may be continued.’ ” 
The President said that he was sure it would be the pleasure of the 
meeting to pass a vote of thanks to Mr. Adee for this donation. The 
prints from these negatives had been prepared by Messrs. Watson, and 
would be handed round for inspection. The subject — the gizzard of a 
cricket —was well known to most of those present, and although he was 
himself unable to appreciate any stereoscopic effect, the photographs 
were nevertheless extremely good. 
A vote of thanks for this donation was unanimously carried.
