I had almost endless trouble in keeping the poultices on and 
preventing the horse from rubbing the parts, for he was not quiet a 
moment ; and one day I thought I should have lost him, for he had 
oroken loose and rubbed his neck so much that the edges of the 
wound were swollen the thickness of my arm. 
In some cases, in which the cautery has been applied to the 
wound, the integument has healed over, leaving an abscess under- 
neath extending into the vein, and producing inflammation there. 
I have seen several cases in which union has taken place in the 
integument ; but abscesses have shown themselves in three weeks 
or a month, often proving that the too rapid healing of the external 
wound does not cure the disease. 
One case in particular you will forgive me for relating. It was 
that of a mare that died in consequence of a rupture of the 
abdominal muscles from some unknown cause, when heavy in foal, 
and after she had travelled with a gig a distance of sixteen miles. 
I saw before she died that there was a tumour formed on the jugular 
vein, and after her death I cut away that portion of the vein and 
examined it. The vessel at this place was from one eighth to 
one quarter of an inch thick, and on the inner coat a deposition 
of lymph existed that extended from one side to the other, for 
about an inch in length, leaving a space on each side sufficient for 
the blood to pass. The tumour occupied a space between two 
valves. The valve above the tumour seemed to be larger than any 
of the others, and a little coagulated blood surrounded the tumour 
between this valve and the one immediately below. There was 
adhesion between the tumour and the parietes of the vein, but none 
between it and the valves. 
This strange growth, and the thickening of the parietes of the 
vein, were confined to the space between the two valves, and broke 
off abruptly above and below, leaving the remainder of the vein 
sound. 
Between the tumour and the bifurcation, a distance of six inches, 
there were two valves, and from the tumour to the breast, a space 
of about twelve inches, there were no fewer than six valves, so that 
the valves were more numerous below than above. 
In one case of inflamed vein the external opening was completely 
healed in two or three days after bleeding, and all appeared to be 
going on well for about a month, when it opened again, and was 
five months in healing. I have heard of the vein being laid open 
through the parotid gland up to the ear, and that a cure has been 
effected, but with a great deal of trouble, occasioned by a sinus in 
the gland. I had once a case in which five or six abscesses had 
formed above the original wound, and the two superior ones burst 
through the parotid gland, the extent of the ulceration being 
evident from the quantity of saliva that flowed through each orifice. 
A cure was effected by a few simple injections. 
Although somewhat objected to in the present day, yet I do think 
that great good may be done by the steady and persevering use of 
fomentations and poultices ; but it must not be merely the applica-
