7. Coronary frog-band. 
2.—Horse’s foot, with hoof removed. 
1. Situation of coronary frog-band. 
2. Coronary substance. 
3. Vascular lamine. 
4, Villi of sole. 
PEAT Xt. 
1.—Horizontal section of wall of hoof, the vascular lamine being shrunk, 
and leaving openings, except at the points, where they unite 
the horny lamine. 
a. Orifices in the wall, into which the villi of the coronary sub- 
stance pass, surrounded by— 
6. Pigment-cells. 
e. Horny lamine. 
d, d. Laminelle (of Fleming). 
2.—Injected vessels of villi of coronary substance. 
3.—Ditto of vascular lamine, two in the centre having coalesced, and 
slightly shrunk in drying. 
4.—Vertical section of coronary frog-band. 
e. Cuticle. 
J. Hair. 
g. Capillaries of sebaceous glands. 
A. Villi penetrating its semi-horny substance. 
5.—Vertical section of wall, including a portion of horny lamine, into 
which the pigment-cells are seen to enter freely. 
2. Horny lamine. 
j. Tubes for villi. 
6.—Cribriform plate at the superior interior part of the wall of the hoof, 
on which the coronary substance rests, with its orifices for 
the passage of the villi.
