FOOT AND MOUTH DISEASE.

What influence the numerous pus-like globules and gran- 
ular cells, with the living organisms in the form of Monads 
and Bacteria, may exercise upon the health of the human sub- 
ject it is impossible, in the absence of direct experiments, to 
determine ; but the evidence in respect of its effects upon the 
young of the lower animals is very conclusive. Some years 
ago my colleague. Professor Simonds, lost three valuable 
calves in one day in consequence of allowing them to suck a 
cow which was suffering from the disease in the early stage. 
He also produced eczema in pigs by giving them the milk 
immediately after it was drawn from a diseased cow. Conti- 
nental observers also allude to instances of the poisonous 
action of the milk on young animals. 
Since the above observations were made, other cases of 
sudden death of calves from sucking the milk of diseased 
cows have been recorded. Within the last few weeks calves, 
which were apparently well when left at night, have been 
found dead in the morning from this cause, and there is too 
much reason to apprehend that, to the young of the mammalia 
in general, the milk from cows affected with mouth and foot 
disease is highly deleterious. Probably the most recent 
experiment with milk from a diseased cow was made in my 
own house. During the early period of the prevalence of the 
disease, when milk was daily sent to me for examination, I 
gave to a young cat a liberal supply of that which was left 
from my experiments. The animal shortly became very 
weak and ill, and, after the first few days, declined to accept 
the diseased milk, although no other kind was supplied in its 
place ; indeed, at the time, the milk on my own table 
contained an abundant quantity of the morbid elements. 
Among the specimens sent for examination were some taken 
from animals which suffered from the effects of the disease in 
one or more quarters of the udder. These examples con- 
tained little else than pus corpuscles and exudatiou cells, 
w 7 ith Monads and Bacteria; the milk globules were few and 
far between. This abnormal condition of the secretions may 
be a subject full of interest for the pathologist, but it is sick- 
ening to know that such morbid matter is used to swell the 
general bulk of the morning and evening quantum of milk 
which is supplied to the population, who, if any suspicion is 
aroused, are quite reassured by the dairyman's entirely 
romantic statement that when cows have the disease all the 
milk dries up.” Meat from diseased animals has also been 
carefully examined, and the results of the investigation are 
altogether satisfactory. No morbid products have been 
detected, and, excepting the presence of some of the parasitic
