810 PLEURO-PNEUMONIA AMONG CATTLE. 
readers may not have an opportunity of referring to the 
article to which I desire to direct attention, and as it was 
deemed worthy of being reprinted for distribution among 
the members of the Epidemiological Society and others, I 
trust that you may consider it also worthy of a reprint in an 
early number of the Veterinarian . 
Nearly five years have elapsed since its first publication 
took place ; some who read it then, and have thought of it, 
might have supposed that the epizootic committee therein 
alluded to had ceased to exist. 
The reprint would enable those who cannot avail them- 
selves of the number of the Veterinarian in which the article 
appears, to note with what warmth the late Mr. Percival 
treated the prospect of co-operation of the members of the 
medical profession, with that of the sister science, the veteri- 
nary. 
I have the honour to be, Gentlemen, 
Your obedient servant, 
J. H. Tucker.

[We have much pleasure in complying with the request 
contained in the foregoing communication, and reprint the 
article in question.] 
“The Epidemiological Society was first intro- 
duced to the readers of the Veterinarian so long ago as 
August, 1850. In our journal for that month, its origin 
and pretensions are set forth in a letter forwarded to 
us by its then pro tem ., but now one of its honorary secre- 
taries, Mr. Tucker, of Berners Street, Oxford Street. In the 
December following, the society, in the interval formed and 
organized, held its first meeting ; on which occasion its dis- 
tinguished president. Dr. Babington, delivered an address, 
characterised no less by the historical learning displayed in 
it on the rise and spread of epidemic disease in general, than 
by the interest it at the time excited, from containing some 
curious and valuable facts in respect to endemics in particular. 
In this eloquent address — an abstract of which will be found 
in our number for January of the present year, 1851 — Dr. 
Babington sets forth c the objects of the society’ to be, ( to 
endeavour, by the light of modern science, to review all those 
causes which result in the manifestation and spread of epi- 
demic diseases — to discover the causes at present unknown, 
and investigate those which are ill understood — to collect 
together facts on which scientific researches may be securely 
based — to remove errors which impede their progress — and
