days after she received the injury, crepitation could be dis¬ 
tinctly heard on moving the joint, which we all know is a 
very unfavorable symptom ; but the peroxide of hydrogen 
injections were kept up till the first of August, when the 
opening entirely healed up, and on the 4th of August the pa¬ 
tient was discharged, the hock slightly enlarged by the accu¬ 
mulation of organized lymph and the patient still showing 
considerable lameness; but the last we heard from her she 
was walking with more ease than when she was discharged. 
On July 21st we were called to see a fine mule that had 
been kicked four days previous on the inside of the right hock, 
and on making an examination found an opening directly into 
the tibio-tarsal articulation. The owner had worked her one 
day after she was kicked, not thinking the injury very severe ; 
still he usually keeps on hand about one hundred head of 
horses and mules, is about sixty years old and never saw an 
open joint before ; if he did he did not know what it was. So, 
telling him what it was and what the result would likely be, 
he said u Go ahead and do what you can for her, for possibly 
she will make a plug mule, but before she was kicked was 
valued at two hundred dollars.” 
The constitutional disturbances were not so aggravated in 
this case as in most similar ones. We applied acanth. blister 
to both sides of the hock and prepared a sol. of per. of hy. 
one to twenty, giving the joint injections of the same once a 
day. We again saw the case three days after and could notice 
no change, but ordered the per. .of hy. injections kept up 
daily, and on the 31st the owner reported he thought the case 
was doing well. We again saw the case October 1st; the 
opening was closed, the patient walking and beaiing almost 
as much weight on that leg as on the opposite one ; no in¬ 
flammation was detected, but the hock was somewhat en¬ 
larged, and the bony structure seemed to be in a normal con¬ 
dition. 
Let us hear from more members of the profession that have 
used peroxide of hydrogen, in regard to its therapeutic value. 
1 find it of value in fistulous tracts of any kind, and have seen 
it used as nasal injections in catarrhal troubles in solution one 
to eight in the human, where it was of great service.
