PHOTOGBAPHICAL SECTION. 
Ordinary Meeting, December 1st, 1864. 
Joseph Baxendell, F.R.A.S., in the Chair. 
Mr. Samuel Cottam was elected an Ordinary Member. 
Mr. Mudd presented four large and very beautiful photo- 
graphs to the society’s portfolio, — two taken in Dunham 
Park, and two in North Wales, by the colodio-albumen 
process. These landscapes were remarkable for their peculiar 
softness and delicacy. 
Mr. Parry called attention to a letter in “ The British 
Journal of Photography,” by Mr. Hislop, claiming the in- 
vention of the camera exhibited and explained by Mr. 
Sidebotham at the last meeting. He also produced the 
Journal in which was the drawing and description on which 
Mr. Hislop founded his claim. After an examination of 
these it was unanimously decided by the members present 
that there was no similarity whatever between the two 
cameras, and that a drawing ought to be published of Mr. 
Sidebotham’s camera. 
Mr. Nevill exhibited some good prints produced by 
making paper sensitive with a solution of salts of nitrate of 
uranium and nitrate of silver, and when the image began to 
appear, developing with sulphate of iron ; the prints were 
only exposed fifteen seconds.
