concussion and all its injurious consequences. On the other 
hand the instant the foot is raised off the ground again, the 
apparatus contracts, and thus becomes prepared for another 
descent: so that, in point of fact, a horse may be said to be 
moving in four spring boxes, or foot-cases , within which his feet 
are actually slung or suspended by their uppermost smfaces. 
Were this not the case, the foot bones— coffin bones as they are 
ca p ec [—would be, from the great weight of the animal’s body and 
the impetus created in action, literally smashed to pieces at every 
Stop. . n -1 • 
These facts, gentlemen, will serve to convince you ot the in¬ 
dispensableness of anatomy , and its concomitant physiology : by 
the one we discovered the existence, arrangement, and structure 
of the laminated apparatus we have been discoursing on; while 
the other has made us acquainted with the uses or functions 
that apparatus performs. 
Before we quit the subjects of anatomy and physiology, let us 
take one other part by way of further illustration ; at the same 
time that it becomes one more instance to shew how all-suffi¬ 
cient and admirable every structure we examine turns out to be. 
We will now lake the Eye. —We will suppose that a bit of dirt, 
or a hay-seed, or some other extraneous mattei, has flown into a 
horse’s eye. How is the animal to get it out ? He possesses no 
hands for the purpose; nor can his companions assist him in 
any way. What then is to be done ? The dirt must not remain 
in the eye; if it does, inflammation will follow the pain and irri¬ 
tation it occasions, and the animal wflll iose his eye. What can 
he do ? By his own will, nothing ; or worse than nothing he 
may fruitlessly rub his eye against the mangel, which m couise 
would augment the evil. 
All-provident Nature foresaw the inconvenience and annoy¬ 
ances that the animal must inevitably, in this respect, be sub¬ 
ject to, and therefore had the precaution to furnish his eye with 
a contrivance no less beautiful than effectual. It consists, gen¬ 
tlemen, in what is called the haw —a part that is often seen pro- 
jecting from the inner corner of the eye. It is a part made of 
gristle; and so shaped as exactly to fit the front or sight of the 
eye, as completely, and much in the same manner, that one side 
of the outer case of a watch fits the inner. Now, whenever 
any extraneous matter gets into the eye, the first thing that hap¬ 
pens is the closure of the lids; which instantaneous shutting of 
the eye is followed by 3 . flow of tears, and the simultaneous pio- 
trusion of this gristly body over the forepart of the eye; the ef¬ 
fect of which is to disengage the extraneous matter from the 
sight, and lodge it upon its own back or exterior, from which it
