PLEURO- PNEUMONIA AMONG CATTLE. 31 1 
thus, as far as we are able, having made ourselves thoroughly 
acquainted with the strongholds of our enemies and their 
modes of attack, to suggest those means by which their in- 
vasion may either be prevented, or if, in spite of our experience, 
they have broken in upon us, to seek how they may be most 
effectually combated and expelled.’ In accordance with this 
coup d’oeil of the c objects 5 of the society it is that its members 
have been carrying on their operations. The field of research 
before them is an ample and a fertile one, necessarily 
divided off into parcels and portions, in the allotment of 
which, as will appear from the following extract out of the 
society’s 4 address/ the veterinary public will find they have 
not been overlooked. 
“ * In order to throw some light upon the whole question 
of epidemic disease, and as an object in itself of important 
inquiry, it will be within the scope of the society to investigate 
the diseases prevailing extensively among domesticated and other 
animals , as well as those that affect the vegetable kingdom . 5 
“In furtherance of this their object, and which most 
nearly concerns us, it is with feelings of pleasure we now 
find ourselves in a situation to announce the recent for-

“ In the Address we have all read and admired, 
we find the highly talented and esteemed President 
of the Epidemiological Society to have stated, that the 
medical professions of all nations have yet much to learn re- 
garding the causes, the means of prevention, and the treat- 
ment of several of the most formidable of the epidemics 
which, from age to age, and season to season, have attacked 
the human race, and wherein we find ourselves invited to 
co-operate in the working out of so important and desirable 
an end, shall we of the veterinary profession stand by as 
silent and actionless spectators ? Shall we not rather buckle 
on our armour and rush into the contest, prepared to afford 
any and every auxiliary in our power in the furtherance of so 
noble a cause? Nay ! have we not epidemics, alias epizootics, 
among our own patients to care for? And is it not our 
bounden duty to learn to understand their nature better, and 
so the better be able to cure them, for it is very well known we
