AT THE LONDON FARMERS’ CLUB. 691 
saying how much we feel indebted to Mr. Cherry for his kindness 
in coming forward on this emergency. 
Mr. CHERRY said — In proceeding to address you in reference to 
a disease so devastating as that to which the name of “ Pleuro 
Pneumonia” has been given, I cannot but feel that this may ap- 
pear presumptuous, when so many talented men have failed to 
bring forward a remedy whereby the ravages of this disorder may 
be mitigated ; and I feel this the more strongly, on account of 
having been called upon to address you at so short a notice. In 
the month of April last, owing to circumstances which had occurred 
in the previous September, I felt bound to tender my services to 
the Club in relation to this particular question ; but several months 
having elapsed without my hearing any thing more of the matter, 
I concluded that it had dropped, and much of the matter which I 
had intended to lay before you was employed by me in other 
ways. Having been called upon, however, by Mr. Corbet, with a 
view to my introducing this subject, I will now do my best to point 
out those things which I think essential to a right understanding 
of this question. In the first place, we must regard it as a politi- 
cal question, involving the well-being of a large portion of the 
community ; not merely affecting those who rear, and endeavour 
to derive profit from rearing, animals, but also affecting the com- 
munity at large as regards the supply of food; for if a disease of 
this kind cannot be arrested, not only will there be loss to the in- 
dividual who is engaged in the rearing of animals, but to the 
public, who will, in consequence, have injurious food placed before 
them. Now this disease, though it is called pleuro pneumonia, is 
only part and parcel of a more general one, and it ought, in fact, 
still to go under the name “ epidemic,” which was originally given 
to it. The disease first broke out in the year 1835 ; that was the 
first notice we had of the malady : but it was not till 1840 that it 
manifested itself among cattle and sheep. Up to that time it had 
been confined to mankind and to horses. It then went on in its 
career, and within a year or two after its appearance, a type of the 
disease, which has since been called pleuro-pneumonia, became 
prevalent ; the disease being principally confined, in that peculiar 
form of it, to cattle, and not being much spread amongst other 
animals. But still, if you examine, you will find that the various 
forms of the disease are all more or less connected with each other : 
though it may happen that one organ will be more particularly the 
seat of the disease than another, and though different animals may 
be differently affected, still the same causes produce these appa- 
rently opposite effects, and therefore we must consider these differ- 
ent forms as part and parcel of the same disease. 
The attempt has been made for a long period to discover a me-
