secondary manifestations (iodism) as when given internally, in- 
tramammary or intravenously. As the result of Hauptmann’s 
investigations, he doubts whether the curative action of the 
iodide of potassium results from the direct contact with the 
germs by the intramammeal injection as stated by Schmidt. 
Following is a statistic regarding the results of treating partur¬ 
ient paresis with iodide of potassium in Austria : From July 
i, 1899, to June 30, 1900, by 41 county veterinarians of Aus¬ 
tria, in 172 cases of milk fever the iodide of potassium treat¬ 
ment was applied ; of these there were 123 severe cases, 18 of a 
middle, and 31 of a light grade. Of these 129 cows 75 per 
cent, were cured completely ; 32 (18.6 per cent.) were slaugh¬ 
tered ; death resulting in 11 (6.4 per cent.) cases. By last 
year’s statistics 75 per cent, recovered and 21 per cent. died. 
After the injection was made of 10 gm. of iodide of potassium 
in 1 liter of water, before 10 hours’ time elapsed, in 76 cases the 
cows got up ; before the 20th hour, 30 more cases, while the 
other 23 cases required a still longer time. Bad results from 
the effect of the iodide of potassium could not be observed.—

Contribution to the Technioue of the Diagnosis of 
Glanders. —Up to date the most positive diagnosis of glanders 
is obtained by the test inoculations. The cat is recommended as 
the cheapest and most easily obtainable animal for inoculation, 
in which on the third day after the inoculation a swelling and 
on the fifth to seventh day the typical glandular nodules are to 
be present. The Russian N. Godzjackv recommends the follow¬ 
ing procedure : Inoculation of the cat with nasal discharge. 
On the third day the cat is destroyed, and the bacteriological 
examination of the internal organs is made (spleen, liver, kidney 
testicle, etc). From the spleen eight cultures are made on po¬ 
tatoes and on agar. Should the bacteriological examination 
have a negative result, then a second or even a third cat is to 
be inoculated. In case the inoculated culture does not give 
positive results in three days, the second inoculated cat is de¬ 
stroyed and examined as No. 1. Should the first investigation 
give positive results the diagnosis of glanders is proved on the 
fifth to seventh day. On the other hand, if the positive signs 
are only obtained from the examination of the second, eight to 
10 days pass away before the results are known. In case of the 
absence of a nasal discharge, the inoculation is made with ex¬ 
tirpated parts of the inferior maxillary gland.—( Thierarzt. Cen-
