disinfected. They then form a thick crust, under which 
profuse suppuration takes place. The same agents are like- 
wise contra-indicated when hemorrhage is still present. In 
this latter case they combine with the blood to form metallic 
albuminates, which lie as an impenetrable layer on the 
surface of the wound, and so hinder the action of drugs 
on the tissue below. 
During his after-treatment, Bermbach advocates removal 
of the dressings every second day, all cheesy material to be 
scraped away with the knife, and the sublimate lotion to be 
used again. He also insists on the animal being kept 
standing in a dry stable—nothing but a stone pavement 
kept clean—and put to regular work in a plate shoe after 
the first or second week. Cure of advanced cases is said to 
be obtainable in from four to six weeks. 
As illustrative of the value of pressure in the treatment 
of canker, we may also draw attention to a treatment advo- 
cated by Lieutenant Rose.* This observer holds that ade- 
quate pressure is unobtainable by packing the foot, and, to 
obtain it, removes the wall from heel to heel, much after 
the manner of preparing the foot for the Charlier shoe, so 
that the whole of the weight is taken by the sole and the 
frog. Tar and tow is then lightly applied, the foot placed 
in a boot, and the patient turned into a loose-box. The 
dressing is repeated at intervals of four or five days until 
the animal is cured. 
Those who have followed this method of treatment have 
modified it by actually shoeing the animal Charlier fashion, 
and keeping him at work, attention, of course, being at the 
same time given to a proper antiseptic dressing. 
Reported Cases.—1. (Malcolm’s Treatment +). The sub- 
ject was a five-year old horse belonging to a client of Mr. 
Olver’s, of Tamworth. The case was an exceptionally bad 
one, for not only was the whole of the frog and sole of the 
near hind-foot cankered, but the disease on the outside
