WATERY FARCY — EXTERNAL DROPSY, &C. 
the coagulum of every parcel of blood abstracted manifests less 
firmness and tenacity, and swims in a larger pool of serum. Draw 
another four pints of blood, and continue the compound mercurial 
ball, and fomentations, and wet bandages, and exercise. 
23 d . — An evident change for the better. The tumefaction in 
the limbs perceptibly pits, and is dropping. Continue medicine, &c. 
24^A. — Progressive improvement. Take the ball only twice 
a-day. 
24/?A. — Amending daily. There being some appearance about 
the gums, and some slight taint in the breath, indicative of mercu- 
rialization, let the ball be given only once a-day. 
29 th. — The cuticle is cracking in places where the inflammation 
and swelling were greatest — upon the inner surface of the off arm, 
and upon the withers as well; and from the cracks is oozing a 
yellow serous fluid, which concretes among the hair. 
31s£ — The cuticle, and hair with it, is desquamating from the 
places where it cracked. He is going on so well there is no need 
of pushing the mercury farther, therefore discontinue his ball. 
June 10 th. — Dismissed to his own stable, free from any swelling, 
save what little is seen in the morning, before exercise, about the 
off fore fetlock, amounting merely to filling. His condition, which 
is a good deal reduced, had better be got up again, gradually, by 
feeding moderately on corn and vetches, and exercise twice a-day, 
not carried to fatigue. 
Case V. — Shewing Swellings of the Limbs accompanied by that 
Disease of the Schneiderian Membrane which by some has been 
called Scarlatina, by others Purpura Hemorrhagica. 
In October 1841, a three-year-old colt, very fat, came to me on 
account of having “ swelled legs.” Some aperient diuretic me- 
dicine was given, and exercise enjoined ; and he was sent away. 
Next day, however, he came back, swelled up to his knees and 
hocks in all four limbs ; and the tumefactions felt warm and firm, 
and gave pain when pressed, assuming all the appearances, in 
fact, of those described in the former cases. Repeat his medicine 
and exercise. 
On the 25th (the following day) he purged freely ; but the 
swellings did not give way from the evacuation ; though undimi- 
nished in volume, however, they feel softer, and pit under the 
pressure of the fingers. Take away six pints of blood, apply band- 
ages to his legs wetted with cold water, and let him walk out 
thrice daily. There is but little fever in the system at present, 
and both appetite and spirits are good.
