the statement again came under my notice, after having been 
thrown aside and forgotten. The subject was a filly foal, half an 
hour old, very symmetrical, and grew up the same, not a pony, 
but a horse in miniature : the sire and dam were both ponies. 
The lengths were taken with great care.

PLEURO-PNEUMONIA— ITS IMPROPER APPLICA- 
TION TO THE PREVAILING EPIDEMIC. 
By Thomas Mayer, sen., M.R.C.V.S. 
A SHORT time ago I observed some very pertinent remarks of 
Mr. Mayhew’s, relative to the misapplication of the term pleuro- 
pneumonia to the prevailing and very fatal epidemic which has 
for some time pervaded the united kingdom, and set at com- 
plete defiance all our remedial measures, which cannot be won- 
dered at when we consider how effectually and extensively its 
ravages alter and modify the original structure of the lungs, a 
viscus of the first importance and essentiality to life itself. 
The disease termed pleuro-pneumonia is one which has long 
been recognised as a common affection of the lungs and the pleura 
enveloping them, and also the thoracic cavity, both amongst horses 
and cattle, and which, by the adoption of vigorous measures, is under 
our controul and management , — not so the prevailing epidemic. 
Pleuro-pneumonia is not an infectious disease; but when we 
daily observe that the introduction of a single diseased animal 
labouring under this fatal epidemic invariably extends its charac- 
ter and ravages amongst the whole of a large dairy stock, seldom
