DISEASES OF THE FOOT. 
can be given. Suppuration, when once established, may be followed by 
any of the above-described complications, especially in cases of pododer- 
matitis parenchymatosa. Swelling of the coronet points to the later 
appearance of quittor, whilst severe lameness, pain on dorsal flexion of 
the toe, and swelling between the bulbs of the heel suggest purulent 
suppuration of the fibro-fatty frog, and alfection of the flexor pedis 
perforans tendon. 
Bad conformation and work on stone-paved streets naturally lessen 
the chances of complete recovery. 
Treatment follows the principles 
above indicated (see treatment of 
“ Acute Inflammation of the Podo' 
phyllous Membrane”). The im¬ 
mediate cause must if possible be 
removed, and the shoeing receive 
attention. For horses with broad, 
flat feet the shoe should be fitted 
long at the heels and should be 
broad in the “ cover.” After 
recent suppurating corn a bar- 
shoe may advantageously be 
applied. On the other hand, 
horses with high, “ blocky ” feet 
often go better in “tips,” Charlier 
shoes, or shoes with thin heels, 
provided no active inflammation 
7 exist. The regulation shoe for 
corn, employed by the great Com- 
pagnie des Omnibus de Paris, is 
a three-quarter shoe, the branch 
of the shoe being cut away on the 
side coiiesponding to the injury. Since adopting it the number of cases 
of corn has greatly diminished. From the 1st of April, 1895, to the

1st of August, 1896, only 44 cases of corn were reported amongst 15,500 
horses. 
In diy com nothing further is required. Paring out corns is 
undesirable, and even injurious, because, after removal of the reddened 
masses of horn, the soft tissues are often exposed, and entrance of 
infectious material facilitated. 
In parenchymatous disease, free exit must be provided for the pus ; if 
necrosis have occurred, the dead tissue should be removed as early as 
possible, and the spread of infection checked, antiseptics being employed 
either to destroy or hinder the development of specific organisms. (For
