of an exploring needle there flowed a reddish serous liquid, 
and upon enlarging the incision, from thirty-two to forty-eight 
ounces of the same were liberated. After a few days sup¬ 
puration appeared, a portion of the skin became gangrenous, 
febrile symptoms complicated the case and healing lasted sev¬ 
eral weeks. I have observed a few similar cases, having the 
wound upon the same region and showing the same history ; 
with these I have applied a very different and more success¬ 
ful therapy. The hair is first clipped over the swelling and 
at the most dependent portion is shaved ; after fundamental 
disinfection, the incision is made at the shaven portion, and a 
short and thick drainage tube sewed in. The latter tube is 
made continuous with the epidermis by iodoform collodion, 
and at the end of the tube a ring of cotton is fastened by the 
same means, in this way seeking to avoid infection of and 
continual wetting of the skin by the dropping fluid. The 
loose skin is now sewed fast to the underlying tissues by deep 
perpendicular stitches, and afterward coating the whole 
sheared surface with cantharidine collodion or other counter- 
irritant completes the therapy. Care is taken that the patient 
does not rub the part; and further, no oats are to be given, 
every other day a small portion of water. On the eleventh 
day the drainage tube and threads were removed, and on the 
seventeenth day the horse was put to the saddle. 
Resume: From the foregoing foundation, borrowed from 
human medicine, and upon the ground of cases related and 
observed, I believe I am justified in stating the following : 
Lymph extravasate, lymphorrhagia or decollement traumati- 
que occurs in the domestic animals as well as in the human 
species. Its causes are : a fall and subsequent sliding ; being 
struck with the pole or shaft in a tangential or oblique man¬ 
ner ; during copulation from the motion of the anterior limbs 
upon the spinal region of the female; from the rubbing or 
striking of the body in going through a narrow doorway. 
Concerning the therapy ; setons are held as dangerous ; all 
fragments of torn tissue are to be removed by injections of 
caustic astringent solutions of the following : zincum chlor. 
io per cent.; ac. phenicum, io percent.; hydrarg. chlor. corros.
