The description of the technique of the examination is to be 
found in the Schweizer. Archivfur Tierheilkunde for the year 
1897 (S. 148). 
Whether veterinary police regulations against this disease 
are required will be seen after the distribution of the disease 
over the country is somewhat better known. 
THE SILVER SALTS OF CREDE AND THEIR 
APPLICATIONS. 
By Adolph Eichhorn, D. V. S., oh The American Veterinary 
Hospital, New York. 
A Paper read before the Veterinary Medical Association of New York County, 
March 6, 1901. 
The preparations which I am to describe are by no means 
new discoveries in the line of medicine, yet I know there is very 
little known about their use and application in veterinary medi¬ 
cine. My attention to their existence was drawn from foreign 
literature by the good results obtained from their use in human 
medicine, but especially by an article of Dr. Angelo Baldoni, 
who carefully studied these drugs as to their antiseptic proper¬ 
ties and their valuable applications in veterinary medicine. The 
Crede salts are three in number—the argentum colloidale or 
collargol, the citrate of silver or itrol, and the lactate of silver 
or actol. 
Collargolum is a non-poisonous allotropie silver, appearing 
in different sized irregular granules, soluble in water in the pro¬ 
portion of 1:100, which solution is black in color. It dissolves 
also in glycerine, in the proportion of 1:25. 
To prepare the solution, I find the best way as follows : 
First, grind the granules, then add a small amount of glycerine, 
which should be slowly and thoroughly mixed, then add the 
water. In the solution we soon notice a slight black precipi¬ 
tate, which cannot be avoided, even in the absence of light and 
air. This preparation is recommended as a most effective general 
antiseptic, which can be introduced into the system without
