160 PROCEEDINGS OF SOCIETIES. 
Council when I say that they feel that if you are determined to 
work with them in making the Society successful, we can together 
command success. For myself, I will give as much time as I can 
to your interests, and uphold the dignity of the Society as far as 
possible; and if we all go in for success, success will be sure to 
crown our exertions. (Loud cheers.) 
David Joy, Esq., Middlesboro-on-Tees, and J. Oxenden, Hsq., 
4, Richmond Terrace, Bayswater, were balloted for and duly 
elected members of the Society. 
A paper by Dr. Greville “On Diatomacex,” was read. (See 
Trans., p. 24.) 
A second paper “On Photomicrography, its application and 
results,” by Dr. Maddox, was read. (See Trans., p. 35.) 
At the conclusion of this paper the President called upon Mr. 
James How, of Foster Lane, who then, by means of the oxy- 
hydrogen lantern, exhibited upon a screen about twelve feet in 
diameter a very beautiful collection of transparent prints from 
Dr. Maddox’s negatives. The definitions of some of the diatoms, 
photographed with a -4;-inch object-glass, were truly marvel- 
lous, and their representation by means of the lantern called forth 
repeated bursts of applause. The extraordinary delineations of 
minute structure which were thus displayed before a large au- 
dience afford strong reasons for believing that photomicrography 
will rapidly extend itself and displace the work of the diagramatic 
artist by its more perfect rendering of hitherto unperceived 
beauties. 
The PrestpENT having invited the meeting to make any re- 
marks upon Dr. Maddox’s paper, 
Mr. R. Brox said it was then too late in the evening to dis- 
cuss the paper very fully. The subject of microphotography 
was, he thought, quite deserving of an entire evening. Ie wished 
to point out, however, that at present the representations were 
mostly those of flat and opaque objects. 
The Prestprent.—Well, we will not despair of being able to 
secure still better results after what we have just seen. Photo- 
micrography is not to be estimated by what it has yet done, but 
rather by what it holds out the hope of doing, and I am sure that 
this the first step in the progress will meet with your hearty 
approval, and I hope that a vote of thanks to Dr. Maddox will be 
passed by acclamation. I would ask you, too, to give an equally 
unanimous vote of thanks to Mr. How, who has so kindly attended 
and exhibited the photographs. We must consider that the 
representation to-night is by no means a fair specimen of what 
the objects really are. The screen which has been employed is a 
very temporary affair, and I dare say many who sat near it will 
have noticed that, in consequence of its shifting about, the picture 
was not always in the same plane, and it was therefore impossible 
to get a good focus. I hope, however, that Mr. How is only 
breaking ground to-night, and that the next time we shall see him 
will be at our soirée; we can then give him a suitable room 
entirely to himself. If he will come and show us these beautiful
