potassium varied from 5-10 grammes. Often there were given 
without injury, 20-24 grammes in the course of one day, and 
to one animal there were given 20 grammes at one time. 
The infusion of potassium iodide is constantly followed by a 
checking of the milk secretion, but this has become normal again 
in the course of a few days, only in two cows has it remained 
lessened for a longer period.

A NEW TREATMENT OF PARTURIENT PARESIS OF 
COWS. 
By Prop. Olof Schwarzkopf, Feushing, N. Y. 
A Paper read before the New York State Veterinary Medical Society, September 14-15, 
1898, with a Postscript written for the American Veterinary Review, 
Of the diseases of domestic animals incidental to seasons 
none is of a more serious nature and more disappointing to the 
veterinarian with rural practice than the so-called milk fever of 
cows. Every year this disease makes its appearance at the calv¬ 
ing season and continues more or less unabated during the hot 
summer months. From the grave character of the disease, from 
the fact that it befalls only valuable, well-bred and well-fed 
cows, from the conflicting theories of the pathology of the 
disease and the utter absence of accurate and controllable 
therapeutics, it remains a disease dreaded by all veterinarians 
whose lot it is to deal with it in practice. 
The theories on the pathology of milk fever, historic and 
present, are interesting not only in themselves but specially so 
as illustrating the periodic changes in medical ideas. They 
can, however, only briefly be referred to, as the object of this 
paper is to be concise and practically instnictive. The oldest 
pathological theory which may have a claim to be scientific 
that of Bentele dating back to the early years of this century. 
He and his followers considered the disease a lacteal metastasis, 
and in old veterinary books we read of milky contents m the 
kidneys, of milky urine, of lactiform substances found in the
