SELECT COMMITTEE ON CONTAGIOUS DISEASES BILL. 655 
very curious facts presented themselves to you as to the out- 
break of this disease, which would shake your opinion very 
much as to its being contagious? — I believe it frequently ex- 
tends (as 1 have before explained to the Committee), from the 
ordinary causes which produced it at first ; that is to say, it 
comes as an epidemic affection, breaks out in that form, and 
spreads ; but I further believe that it not unfrequently ex- 
tends itself from one part of the country to another, and 
among a herd of cattle also from the ordinary influence of 
contagion. 
122. Take a large building, in which cattle are placed for 
stall feeding; you find cases in different parts of that build- 
ing, and you find that a beast standing next to the beast 
affected may be the last affected? — We frequently meet with 
instances of that description, but that does not militate 
against the opinion of the disease being contagious. A 
disease may be contagious, and remarkably so, but ail ani- 
mals are not equally susceptible of taking the contagion at 
the particular time of their first exposure. For example, two 
individuals may pass into the Small Pox Hospital, both of 
them unprotected by vaccination, one shall take the disease 
immediately, the other shall resist it entirely; and that 
which is a fact with regard to the spread of disease in man, 
is a fact with regard to the spread of similar disorders in the 
lower animals. 
123. You would not say that pleuro-pneumonia was con- 
tagious in the same degree that you would say glanders was ? 
- — I think pleuro-pneumonia is equally contagious with 
glanders, 
124. Do you think that in the case which I have alluded 
to, of a horse standing next to another horse affected by 
glanders, sharing the same food every day, feeding out of’ 
the same trough, the disease would be more likely to be 
communicated in the case of glanders than in the case of 
pleuro-pneumonia? — Glanders, I believe, to be a disease not 
strictly infectious, but contagious ; pleuro-pneumonia I 
believe to be infectious, that is to say, exhalations arising 
from the diseased animal's body become disseminated through 
an apartment where a certain number of animals are placed, 
and some of the animals susceptible take it ; but as to 
glanders, a glandered horse might be placed at one corner of 
a stable, and if kept apart from other horses in that stable, 
the exhalations arising from his body would not disseminate 
the disease. Glanders is not an infectious disease, but a 
contagious one. The matter that flows from the nostrils 
coming in contact with the nostrils of another horse would
