tain a dense network of capillaries and nerves. The causes of 
the above disease are various, but most frequently at the railroad 
stables, from, hard driving over the stone pavement and in warm, 
muggy weather, where the animal is allowed to stand under the 
shed to dry off before putting in the stable. The animal thus ex¬ 
posed to drafts of cooler air becomes chilled on the surface of 
the body; a condition of hypersemia of the vessels existed when 
the animal was brought in off the road, and this chill interferes 
with the return of circulation from this part; congestion and stasis 
follows, then an exudation of leucocytes takes place. If this is 
not excessive, resolution may follow, by the absorbent vessels 
taking up this exudate; while on the other hand, if this exuda¬ 
tion be sufficient to block the absorbents, undue pressure will 
follow and structural changes take place, with suppuration and 
separation of the wall from the podophyllous tissue. 
The treatment I have found most efficient for these cases is 
to remove the shoes and put the affected feet in as hot water as 
they can bear; keep in for three or four hours. When removed put 
on hot flaxseed meal poultice; give internally tr. aconiti gtts. x, 
every two hours for first day; alternate with nit. potassa, § ii? 
four times a day; keep up the bath, poultice and potash till the 
stiffness is gone, which generally is accomplished in four to five 
days. Slings are of little benefit, but care must be taken to give 
the animal a large loose box and plenty of bedding, and prevent¬ 
ing bed sores.

The consideration of the thoracic aspirations is of particular 
importance for the essential enlargement of the cavities of the 
heart. This aspiration of the thorax, which is conditioned by the 
negatively exercised pressure of the lungs, would necessarily
