FOOT AND MOUTH DISEASE. 
affected with the malady; and fatal effects have followed the 
administration of the milk to youn^ It has been 
alleged that there is not any direct evidence of injurious con¬ 
sequences arising from the consumption of the milk by human 
beings; but it must be remembered that the fluid is very 
rarely taken immediately from the cow, and still more rarely 
in an undiluted form ; and it may be not altogether an 
unfortunate circumstance that the decrease of the secretion 
during the prevalence of the disease necessitates a large 
admixture of water in order to keep up the quantity which is 
required for daily consumption.

In the early stage of the disease the milk presents few 
abnormal characters : the specific gravity falls to 1024, and the 
milk-corpuscles are always found to be arranged in clusters, 
as shown in fig. 1. A few minute moving specks are 
also seen under the quarter-inch objective, and these under 
the l-2oth are resolved into bacteria and spherical bodies. 
When the disease is fully developed, about the third day 
from the first appearance of vesicles, the milk invariably con¬ 
tains morbid products of a very pronounced character, which 
are shown in fig. 2. This specimen was taken from a cow
