PHTHISIS PULMONALIS VERMINALIS.

it is through it that the whole animal machine maintains its rela¬ 
tions with the ground, and that it adapts itself in its various 
movements, so to speak, to its roughness. It is this that, as a 
last spring, distributes aud modifies the force of all the move¬ 
ments of the horny mass of the body, whose columns, the legs, 
may be considered as the resultant. Intermediate with the body 
and the ground, the foot transmits all the actions of weight 
reaching it, and also between the body and the sensorium, toward 
which all sensations resulting from its contact with surrounding 
external substances return, the foot then becoming at the same 
time an organ of feeling. To adapt it to this triple formation, 
nature has given to it three properties, in appearance incompati¬ 
ble with each other, which it has, however, harmonized, viz : first, 
a very great external hardness, due to its horny envelope; second, 
a certain amount of flexibility, the combined result of the phys¬ 
ical properties of its cortical envelope and of the mechanical dis¬ 
position of its different parts, and thirdly, a highly developed 
sensibility resulting from the high organization of its tegumen¬ 
tary membrane. ( Bouley .)

PHTHISIS PULMONALIS VERM1NALIS. 
By C. H. Peabody, D.V.S. 
(Bead before the United Slates Feterinari) Medical Association.) 
Mr. President and Gentlemen : Hoping the following report 
of some cases and autopsies made by myself on cattle suffering 
with phthisis pulmonalis verminalis will be interesting, I beg to 
ask your attention for a few minutes. 
In October, 1880, I was requested by the Secretary of the 
Board of Health to accompany him to the village of Ashton, in 
the town of Cumberland, B,. I., to the farm of a Mr. Jenks, and 
examine some cattle reported as having pleuro-pneumonia.
