same ingredients in the same manner until the wound becomes 
healthy and granulating. 
It is only for the sake of the record that we refer to the exclu¬ 
sively surgical treatment, based upon the erroneous idea that the 
fici of canker are abnormal products, deeply implanted in the tis¬ 
sues beneath, and where it was advised to look for the imaginary 
roots of these fici at their extreme limits. In this treatment, not 
only the diseased horn was removed, but the entire sole, the plan¬ 
tar cushion and often the plantar aponeurosis was excised. This 
practice, advised by Lafosse junior, was also recommended in the 
veterinary schools by Chabert in France, and Dieterichs in Ger¬ 
many. It prevailed for a long time, though experience showed 
that the wound resulting from such an operation was of very slow 
recovery, that the frog especially could not be regenerated, that 
there remained a central ulcer, and that it gave rise to such a mal¬ 
formation of the foot that the animal remained lame for a long 
time, sometimes for life. Notwithstanding these objections, ob¬ 
served by Jeaune, Girard and Eichbaum, this treatment is still 
followed by a few who prefer it to the simple operations of Sol- 
ley sel, which consists in the division of the loose pieces of horn 
and the excision of the fungoid projections. 
We have thus far only spoken of the local, without referring 
to the internal or constitutional treatment of canker, recommended 
by those who look upon the disease as constitutional. Without 
believing that it can have any real curative effect, we, however, 
admit its usefulness, when the disease is of old standing, and that 
the animal has suffered much by it. Ferruginous preparations are 
specially advisable, and we prefer the carbonates that are used by 
Delwart to the sulphates recommended by Prevost, Delaval and 
Hertwig, and it is well to unite them with bitters and tonic pow¬ 
ders. Arsenious acid is prescribed internally by Delaval, Feuil- 
lette, Niederberger, Obich; and other alteratives, such as mercury, 
which we would not advise. Nor cau we understand how any 
benefit is to be derived from diuretics and purgatives, and espec¬ 
ially from the use of external emunctories, such as setons.
