positively do better, and work harder on shorter feeds than he could 
before—without, as far as I am aware, a single drawback to qualify 
them. In short, I know of no modern innovation in the stable 
management of horses at all to be compared to this, and therefore 
am not in the least surprised at witnessing its almost universal 
adoption. 
Trusting these few cursory remarks may lead to a better under¬ 
standing of the causes affecting, and, of course, a more rational 
treatment of the horse at this peculiarly susceptible season of the 
year, I may conclude with observing, that, although among those 
with whom we have principally to do, that is, trainers, stud grooms, 
jockeys, et id hoc genus,'' we occasionally find some whose ob¬ 
stinacy proves that where ignorance is bliss, ’tis folly to be wise 
yet that, in general, they are open to conviction, and ready to at¬ 
tend to reason, provided it is laid before them in a moderate and 
conciliatory manner, instead of being dogmatically asserted and 
authoritatively insisted on. 
RHEUMATISMAL INFLAMMATION OF THE SYNOVIAL 
MEMBRANE OF THE SESSAMOID BONES IN THE 
HORSE AT THE CLOSE OF PLEURISY. 
By M. B0ULEY,yw72., Assistant Professor at the Veterinary School 
of Alfort. 
There are certain diseases well known to veterinary practi¬ 
tioners, and often observed by them, which have never been well 
described in our works on pathology. The species of lameness 
which will be the subject of this paper is an illustration of this. 
Horses that have recently suffered from pleurisy, or pleuro¬ 
pneumonia, are often attacked, without the slightest warning, by 
violent lameness. The time varies from fifteen to thirty days after 
the cure of the pleurisy. Sometimes only one of the fore legs is 
attacked; sometimes both, and, very rarely, all four legs, begin¬ 
ning with the anterior limbs. 
The lameness usually appears all at once, and without any ap¬ 
parent cause. On examining the limb, we find, at the inferior 
part of the flexor tendons and above the fetlock, a small round 
tumour, so tender that the animal cannot bear the least pressure 
upon it. This tumour, which has its seat on the sheath of the ses- 
samoid, appears to be the result of violent inflammation of the 
serous membrane which lines that cavity. In most cases it seems 
limited to or fixed (cantonnte) in the spot where it first appears : 
sometimes, however, it spreads from below upwards through the
