PROCEEDINGS OF SOCIETIES. 
Mepicat MicroscoricaL Society. 
Av the Meeting of this Society on Friday, Feb. 19, Dr. J. F. 
Payne, the President, in the chair—the minutes of the previous 
meeting were read and confirmed. 
Dr. D. B. Woodman read a paper “On a Natural Method of 
Mounting certain Microscopic Specimens,” which consists of putting 
up urinary deposits, sputa, &c., in their mother liquor, with or 
without the addition of a few drops of a concentrated solution of 
crystallized carbolic acid, and then thoroughly cementing round the 
edge of the cover-glass with some good cement. Dr. Woodman 
had specimens which had been preserved by this method for fourteen 
years without change. He also stated that epithelial casts could 
be kcpt thus for some months, though they ultimately became use- 
less. He did not think that asphalt varnish deserved all the abuse 
that was levelled at it. 
D.. Pritchard objected to asphalt unless prepared as used by 
Mr. Miller, viz. dried and redissolved in dammar varnish. 
Mr. T. Durham and Mr. Groves thought a mixture of asphalt 
and gold size in equal proportions formed a very tough cement. 
The President preferred Frankfort cement. 
Mr. Needham then described a method he had adopted for 
marking specimens in hardening solutions by the use of coloured 
glass beads—black representing No. 1; red, No. 5; green, No. 
10 &c., so that by a combination of these any number could be 
produced. A numbered record of all the preparations was kept in 
a note-book, so that any specimen could be found with ease. 
Mr. EF. H. Ward then exhibited and described a Swiss gauge, 
which he used for measuring the thickness of covering-glass. 
The meeting terminated with the exhibition of a number of 
specimens.
