Having thus summarily enumerated the symptoms, it remains for 
me to enter into a more minute detail as regards some of the promi- 
nent ones. Consistent with the amount of pain do we find existing 
a corresponding amount of constitutional disturbance, and hence 
we find a feverish condition of the system. The pulse, at the onset, 
is not materially increased in rapidity or altered in character ; but 
subsequently it assumes a small and hard feel, provided it is an acute 
case. In a mild attack the number of pulsations will be only two 
or three in advance of the normal standard, yet it will possess an 
oppressed feel. 
A consideration of the different stages through which the limb 
passes, from the commencement of the attack to the time when re- 
solution is perfected, or some morbid condition of the leg remains as 
a sequel, is sufficiently evident to render comment upon it a necessity, 
in order to understand more explicitly the various conditions assumed. 
To expedite the enumeration of these local symptoms I shall discuss 
them in three stages, viz. a congestive, an acute or inflammatory, and 
a passive or cedematous. 
The term congestive I have applied to that condition preceding 
inflammatory action, and as such a condition, especially in this 
malady, is not easily discernible, and in the majority of instances our 
aid is never sought until inflammatory symptoms are clearly evident, 
it only remains for me to specify the seat of the congestion. This 
I believe to be in the areolar tissue of the limb, both that sub- 
jacent to the skin and that surrounding and connecting the 
muscles, vessels, and nerves ; in this site of vascular filaments does 
the congestion take place, and to which inflammation succeeds in 
due course. 
The first local inflammatory symptom noticeable is pain, which is 
not only evidenced by the lameness exhibited when the animal 
essays to progress, but is greatly increased when pressure is applied 
to the inner side of the limb. The swelling is first perceptible, and 
to the greatest extent, on the inside of the thigh or arm (according 
to the limb affected), taking a downward direction. In a few hours 
the limb grows larger, and eventually the increased size of the 
leg below the hock (supposing it to be a hind leg) is almost 
equal to that of the thigh. The limb has now a round appearance, 
and, if examined, will, upon the application of gentle pressure, im- 
part to the fingers a feeling of tensity, and upon increasing the pres- 
sure an almost elastic condition is noticed ; there are not, during the 
existence of this stage, any signs of pitting. In some severe cases 
a peculiar sweat will be apparent oozing from the skin. Now do 
the constitutional symptoms run highest, now is there an altered 
and accelerated condition of the pulse, increased respiration, febrile 
condition of the surface of the body, hot and dry mouth, partially 
suppressed secretions, congested visible mucous membrane, &c. 
Little or no pain is occasioned by pressing the outside of the limb, 
but severe pain is caused when the pressure is applied to the inner 
side along the course of the principal vessels and nerves. There 
is, i. e., when the swelling is not so great as to exclude it, a corded
