have been there for some time. In this ease, culpable 
though he may appear, there is every excuse for the 
veterinary surgeon. 
Once the cavity is opened at the toe in the neighbourhood 
of the white line, then diagnosis is easy. A blunt piece of 
wood, the farrier’s knife, or a director may be easily passed 
into it, sometimes as far up as the coronary cushion (see 
Fig. 129). Issuing from the opening is seen occasionally

for, plainly enough, it has had its origin in chronic 
inflammatory changes in the keratogenous membrane. 
Disease of the horn and loss of its substance may, how-

dition, under the title of ‘External Seedy-Toe,’ is to be 
found!in vol. xxix. of the Veterinary Journal, from which 
we borrow Figs. 130 and 1381. 
In Fig. 180 it will be seen that the disease commences at 
the plantar surface of the toe, and extends upwards and 
inwards. The same condition may also appear anywhere 
between the coronet and the ground, gradually extending 
into the substance of the wall, as shown in Fig. 131. 
According to the writer, Colonel Nunn, the progress of the 
disease in this latter case appears to be faster in a downward
