PROCEEDINGS OF THE SOCIETY. 
possible that, ten years hence, the information given in this book might 
be regarded as too antiquated to be of farther service. 
The President said that Mr. Curties had sent for exhibition a nose- 
piece which had been devised for rapidly attaching an objective to 
obviate some of the disadvantages in the older form of a similar con- 
trivance where the attachment was made by a pinion, which might happen 
to be in some inconvenient position. The new form was made with a 
ring, which was much more easy to work. The article described was 
exhibited to the meeting, and the method of its application practically 
demonstrated. 
The thinks of the meeting were given to Mr. Curties for sending, 
and to the President for exhibiting and explaining, this useful piece of 
apparatus. 
The President said they had received a paper, ‘On a Simple Method 
of Photomicrography,’ from Dr. G. M. Giles, who was at present in 
India. Having read the principal portions of the paper to the meeting, 
the President further remarked that it would be seen that the author 
described what he might call a contrivance for rough-and-ready work. 
In India they would not be likely to have at hand any of the appliances 
we had, and Dr. Giles in his paper had described how he had managed 
without them. His remarks as to low-angled lenses would, no doubt, bo 
the portion of the paper most likely to be criticised by those who were 
practically acquainted with the subject, and his use of these would no 
doubt largely accouut for the unfavourable comparisons made between 
jihotographs and drawings; for he thought it would be admitted by all 
who knew anything about the subject, that if photomicrographs were 
taken properly, no drawing could at all compare with them for accurate 
scientific work. Where, however, the best modern apparatus was not 
available, one had, of course, to make use of what was ready to hand, 
and that described in this paper was a cheap way of making a “ rough- 
and-ready ” vertical photomicrographic apparatus 
The thanks of the meeting were unanimously voted to Dr. Giles for 
his communication, and to the President for reading it to the meeting.
