THE BACILLUS OF GLANDERS. 
NEW MOUNTING MEDIUM. 
ie a regular meeting of the State Microscopical Society of I]- 
linois, held February 8th, 1884, Dr. H. J. Detmers,gave a very 
interesting account of a case of glanders, showing the bacillus 
of the same, which is quite similar to the bacillus tuberculosus, 
but larger. He had examined the discharges from the deceased 
animal and found many micrococci which were formerly sup- 
posed to be the cause of glanders, but he could account for 
these in this case, as the stable in which the horses were kept 
was very dirty, accounting for the presence of many forms of 
bacteria, ete. 
The bacillus of glanders is stained by methyl violet, not by 
ordinary staining fluids. 
In the course of his remarks, the doctor referred to, and 
exhibited the bacillus found by Prof. Burrill as the cause of a 
disease of the roots of the strawberry plant. 
Mr. B. W. Thomas showed some slides prepared by Prof. 
Hamilton Smith, mounted in his new medium. The following 
is the report of the committee appointed to examine the slides: 
To the State Microscopical Society: 
Your committee to which was referred the slides of diatomacez 
mounted ina new media prepared by Prof. H. L. Smith, of eT 
New York, respectfully report as follows: 
Your committee carefully examined the slides submitted to them 
but gave special attention to the slides of amphiplura pellucida 
mounted in a nearly white or colorless medium whose refractive index 
is stated to be 2—. 
A new Bullock professional stand with a ten inch tube was used. 
It was fitted with a condenser made on the Abbe pattern by Mr. 
Bullock, the numerical aperture of which was stated by the maker to 
be 1-23. The condenser was used with a homogeneous immersion 
fluid, (cadmium chloride in glycerine.) The illumination was fur- 
nished by a kerosene lamp with a flat wick turned edgwise toward the 
mirror, and the light was reflected through the condenser by the con- 
cave mirror. 
The objectives used were, first, a dry 1-6 of Bausch and Lomb, 
said to be of 140° air angle with, a Beck No. 3 eye-piece, which gives a 
supra amplification of 13.88. The angle of light from the condenser
