recovered after ammonia had been injected into the veins. The 
writer may add that in his experiments with the liquor ammonia 
the results were astonishingly disastrous. These experiments 
will be related in another part of this paper. 
The action of the venom of the copperhead (Ancistrodon con- 
tortrix) has been studied in 1883 by Dr. Isaac Ott, of Easton, 
Pa., and finally has appeared the magnificent study of venoms by 
Dr. S. Weir Mitchell and Dr. Edward T. Keicliert, published as 
one of the “ Smithsonian Contributions to Knowledge.” So far 
as the writer knows, with the exception of a few unimportant 
papers, the subject of serpent poisoning and antidotes has in this 
review been brought up to date.

FATAL FRACTURE OF A SMALL METATARSAL BONE-SUPPURA 
TIYE SYNOVITIS. 
By M. W. Trisohler, D.V.S., House Surgeon. 
The patient was a chestnut gelding about nine years of age. 
used for light road purposes. 
History .—While being led out to the watering trough on the 
evening of the 2d of June he was kicked by another horse on the 
off hind leg, in the region of the hock; following the infliction of 
the injury no lameness whatever was manifested until several 
hours had elapsed. The precaution was taken to prevent the ani¬ 
mal from lying down, and a cold water bandage applied during 
the night. = 
When seen the following morning a superficial abrasion was 
noticed upon the superior extremity of the metatarsus and upon 
4ts postero-external aspect; but very little swelling about the point 
and some local heat; lameness, however, was excessive, the ani¬ 
mal simply resting lightly upon its toe ; crepitation could not be 
determined. Diagnosis withheld; fracture suspected; the ani¬ 
mal placed in slings and an opium and lead solution prescribed.
