SELECT COMMITTEE ON CONTAGIOUS DISEASES BILL. 35 
but we did not find any cases of the disease till we got some 
considerable distance into Galicia. At the foot of the 
Carpathian mountains, at a village called Kamienica, we met 
with the disease, and likewise in an adjoining village called 
Zabrzez, in the circle of Kroscienko ; in those two places 
we remained and studied the nature of the affection. 
186. Describe, if you please, the nature of the disease, and 
whether it is susceptible of medical treatment? — It is a 
disease which is held by the Austrian and Prussian authori- 
ties, and all others that have had an opportunity of seeing it 
from time to time, to be in general an incurable affection. 
Many animals, however, have recovered when placed under 
medical treatment. It is a highly infectious disease ; none 
more so. It is as infectious among cattle as small-pox is in 
the human subject, or small-pox among sheep. It produces 
a per centage of deaths varying from perhaps 80 to 90 
per cent., when allowed to run its course. The animals 
rarely live for more than four or five days from the time of 
their being observed to be unwell. It is an affection also 
which is incubated in the system of an animal for a period of 
not less than seven days, and according to some observations, 
it seems occasionally to be incubated as long as twenty-one 
days. I may observe, however, that this is a point that 
requires further investigation, because it appears to me to 
be an anomaly that any disease should vary so long as from 
seven to twenty-one days in its periods of incubation. Pro- 
bably such cases depend on secondary exposure to the 
infection. When the animal sickens, the disease first shows 
itself by twitchings of the muscles of the body, more par- 
ticularly of the muscles of the neck and shoulders, and those 
of the hind quarters. The twitchings are accompanied also 
with tremors and staring of the coat. The animal in this 
stage of the disease is in a condition of body that might 
easily be mistaken as depending on exposure to cold. It 
therefore appears that not unfrequently the disease in its 
early stages has been overlooked, and the indisposition of the 
animal has been attributed to wrong causes. 1 may give as 
an example that in the outbreak that took place in Zabrzez, 
and which depended upon the introduction of some Steppe 
oxen, that those animals were supposed to have taken cold, 
and to produce a warmth of body they were placed among a 
number of healthy animals. This is sufficient to show that 
the disease has often no striking marks of suffering at its 
commencement. In the course of a few hours the appetite 
fails, and the general surface of the body becomes of an 
irregular temperature, and the pulse gradually rises ; there
