OBSERVATIONS ON THE ANATOMY AND PHY- 
SIOLOGY OF THE HORSE’S FOOT. 
By George Fleming, M.R.C.V.S., Royal Engineers. 
( Continued from p. 670.) 
The Lamince . — Immediately beneath the coronary cushion 
and coronary zone we come to the tegumentary tissue cover- 
ing the front, sides, and a small part of the inferior face of 
the os pedis. At a glance it will be noticed that the integu- 
ment, which had been so greatly thickened to form the promi- 
nent cushion just described, submits to another abrupt modi- 
fication at the commencement of the white zone, by becoming all 
at once greatly attenuated, and transformed into a wonderful 
series of vertical ridges or “ vascular laminse” (fig.l 2,f), whose 
study is of much moment to the comparative anatomist and 
pathologist, as they have proved for some years a fertile source 
of discussion and speculation. A little examination will also 
demonstrate that this thin derm has, in a curious manner, 
become confluent with, or so closely connected to the perios- 
teum (the membrane covering bony surfaces) of the pedal 
bone, that they cannot be separated, and, in fact, form one 
firm, closely-attached, fibrous membrane. 
In structure this tegument, or “ dermo-perioste,” exhibits a 
very marked predominance of white or inelastic fibres over 
the elastic ; and this fact, together with its close attachment 
to the bone, proves that fixity, and not elasticity, was the 
object chiefly sought to be attained in this region.
