PROCEEDINGS OF THE SOCIETY. 
Meeting of 21st June, 1893, at 20 Hanover Square, W., 
The Rev. Edmund Carr, M.A., in the Chair. 
The Minutes of the Meeting of 17th May last were read and con- 
firmed, and were signed by the Chairman. 
The List of Donations (exclusive of exchanges and reprints) 
received since the last meeting was submitted, and the thanks of the 
Society were given to the donors. 
From 
M. I. Cross and M. J. Cole, Modern Microscopy. (8vo, London, 
1893) The Publishers. 
O. Janson, Versuch einer Ubersicht iiber die Kotatorien-Familie 
der Philodinaeen. (8vo, Bremen, 1893) Mr. C. Eousselet. 
Crystals and a Slab of Selenite from Utah Dr. J. E. Talmage. 
Dr. W. H. Dallinger called attention to a thoroughly practical and 
extremely useful little book which was one of the donations. It was 
entitled 4 Modern Microscopy,’ and consisted of two parts, the first of 
which, by Mr. Cross, dealt with the instrument and the manner of using 
it, and the second, by Mr. Martin J. Cole, was devoted to the preparation 
and mounting of objects. Although consisting only of 104 pages, it 
dealt with the various questions in a masterly way, and was a book 
which he should certainly commend to the attention of those who were 
beginners in the use of the Microscope. 
Prof. F. Jeffrey Bell said that at the preceding meeting it had been 
proposed to fill the vacancy caused in their list of Honorary Fellows 
by the disappearance of Prof. Fol, by the election of Dr. Robert Hertwig. 
It had since been discovered that a mistake had been made in the 
Christian name of the gentleman who had been proposed, and it was 
desired, therefore, to rectify the error by submitting a fresh nomination 
paper in favour of Dr. Oscar Hertwig. 
Dr. J. E. Talmage, of Salt Lake City, Utah, exhibited and described 
some specimens of selenite. He said that he was by no means sure that 
the presentation of such [large] specimens as were on the table, before a 
Microscopical Society, was strictly appropriate. Certainly, at first 
glance it would appear that the Microscope was hardly called for in the 
examination. However, as selenite possesses some peculiar optical 
properties, there might be a shadow of propriety, enough at least to 
serve all needed purposes of excuse, in his taking their time that night 
in offering such an exhibition. 
In the spring of 1892, while prosecuting a journey along the course 
of the Colorado river for the purpose of visiting some of the numerous 
cliff dwellings in the canyons which give passage to the tributaries of 
1893. 2 R
