A CASE OB^ AMPUTATION OF THE PENIS. 5G9 
same principle as the caustic clams. I next proceeded cau¬ 
tiously to incise the lower portion, securing by ligature in my pro¬ 
gress the pudic arteries, and the other vessels of importance*. 
Near to the side of the penis I met with an encysted tumour, 
containing some thick crude offensive matter: on cutting 
through the urethra, a purulent secretion escaped ; another cut 
carried my scalpel through the penis, which, by its retraction, 
prevented me from securing a vessel on its dorsum, and which 
continued to bleed rather freely for a few minutes, partly, I pre¬ 
sume, from the corpora cavernosa. Having completed the ope¬ 
ration, and released the animal from the rope, he got up imme¬ 
diately. I had him led into the stable, and, though the parts 
then bled freely, in ten minutes the hemorrhage ceased, and no 
untoward symptom afterwards made its appearance. 
My after treatment consisted in keeping him for a few days 
on a low diet, giving a mild dose of physic, w^ashing the parts 
every day with a tepid solution of chloride of lime, and dressing 
afterwards with turpentine ointment and compound tincture of 
myrrh. 
Part of the glans penis appeared gone, and the remainder 
scarcely discernible from the other portions of the penis, the 
external part of which, as well as the apposing part of the 
sheath, were covered with ulcerations, while many little ab¬ 
scesses were found between the layers of the tegumental covering. 
I have now the gratification to say that the pony is perfectly 
recovered, and voids his urine with ease. 
The portion excised weighed upwards of five pounds, and, 
upon dissecting it afterwards, I discovered that the inner surface 
of the urethra, from the place of excision downwards to its ter¬ 
mination in the glans penis, was in a complete state of suppura¬ 
tion and ulceration, which had produced an artificial opening 
about four inches from the end of the penis, below which there 
was no passage, nor scarcely a vestige left of the existence of 
any canal. 
♦ It beinf( asked me how lon^ the ligatures would be before they came 
away, I subjoin the following observations:—In the present case the time 
they stayed on was eleven days ; and having the misfortune some time ago 
to wound one of the plantar arteries with the point of my knife in perform¬ 
ing the operation of neurotomy, I observed that the ligatures were thirteen 
or fourteen days before they could be detached from the wound.
