opposite shoe as to break the skin and make a very ugly wound, which 
induced so much pain and inflammation to the foot°as to brin^ on a 
high state of irritative fever. Ihe symptoms when I next saw him were 
—pulse between 70 and 80, breathing hurried, leg continually drawn up 
under the body, animal frequently lying down and moaning, then 
jumping up again as though the pain was beyond endurance, and I have 
no doubt it was. I at once had the shoes off, slightly thinned the soles, 
placed the off 1 hind foot in warm water for a time, then dressed with 
solution of Lq. Plumbi and solution of the extract of belladonna, and 
afterwards put the foot in a large bran poultice, and gave three times a 
day the following mixture ^ Spt. iEther Nit. ^iss, Liq. Ammon. Acet. 
3 iss, Tr. Aconite (Fleming’s) p|xx. 
I continued this treatment for three or four days, and still the animal 
was suffering great pain, although not quite so acute. I now began to 
find the discharge had mixed with it what was very like synovia. I then 
changed the treatment and applied flannel swabs around the coronet, 
keeping them continually wet with cold water, and applied all over the 
coronet two or three times a day Sol. of Zinc Sulph. At the end of 
about ten days the coronet was still enlarging, and the animal almost 
suffered as much as pain as ever, the foot never being near the ground. 
I now thought I would examine the sole again and had it completely 
removed, finding that the pus had gravitated till the whole of the sole 
was hollow, and that a large sinus extended completely through the foot 
into the navicular joint, and from which there was a copious discharge of 
synovia. I then tacked a flat shoe on the foot with two or three nails 
so as to be able to confine the dressing, and injected just within the 
wound, from the bottom, a weak solution of Hy. Chlor., and applied a 
smart blister to the coronet; but do what I would, and I think I tried 
almost everything, all was of no avail. No sooner did one sinus seem to 
heal up than another broke out, and finding that the discharge was now 
mixed with blood and was becoming fetid, I concluded that the case 
was hopeless, and, therefore, had him destroyed and have brought the 
bones of the foot for your examination. From their appearance you 
will see how utterly without hope the case was, as the os corona, os 
naviculare, and os pedis are all involved in disease; ulceration of the 
whole of the articular surfaces, and in the case of the os corona the 
ulceration extends to both sides, and a large amount of morbid bone 
has been thrown out; the coronal process of the os pedis has completely 
disappeared, and from the appearance of this portion of the bone I am 
somewhat inclined to think that it was here the mischief first com¬ 
menced (perhaps by fracture). 
I now want to draw your attention to those injuries which I find so 
frequently occurring in colliery practice, viz. the walls of the foot being 
cut through by a jagged nail, or by the wheel of a tub or waggon running 
over the foot; these injuries, if attended to at once, are not so difficult 
to treat as would at first sight appear. I first have the part thoroughly 
cleansed from all grit and dirt, then with the rasp or knife remove the 
sharp edges of the horn, which will be found to be pressing upon the 
inflamed and swollen sensitive laminee beneath, endeavouring to round 
the edges and removing any horn that may be loose or detached, then 
immerse the foot in a pail of warm water and apply a good bran poultice 
frequently renewed. After a day or two I remove the poultice and 
apply to the wound a salve composed of tar and lard melted together, 
to which I add, when cold, sulphate of zinc §j to 3 j ; this ointment is 
applied on tow, and maintained in position by continuous folds or 
wrappings of tarred cord. I generally find these cases do well, but every
