OBSERVATIONS ON THE ANATOMY AND 
PHYSIOLOGY OF THE HORSE’S FOOT.

Physiology of the Horse’s Foot. 
(Continued from p. 648.) 
That the horn of the wall is carried along the grooves of 
the living laminae might not only be readily inferred from 
reasoning and analogy, but it is also easily put to the proof 
of experiment. If, from the hoof of a living animal, we re- 
move k portion of the wall about its middle, and as deep as 
the surface of the podophyllae, leaving only a narrow strip 
of horn attached transversely to each side of the chasm, while 
above and below it is entirely isolated (fig. 20), we shall find 
that in time, during the growth of the crust, this hand main- 
tains its transverse direction unaltered; whereas, had the 
other portions of the wall continued to move downwards in- 
dependently of the laminse, and through the impulsion pro- 
duced by the addition of new matter at the coronet alone, it 
must have become incurvated from its connection with the 
body of the wall by its extremities, which would be carried 
downwards, the middle meantime remaining in the same 
position. 
A still more convincing experiment is the following : — In- 
stead of allowing the band of horn to remain attached to the 
mass of the wall by its two ends, cut these off, leaving the 
middle of the piece entirely separated on every side from the 
crust, and retained only by its attachment to the living laminee
