It should be noted that the action of the induction coil, mounted as
this was, was very feeble and not very painful; and yet it was very
disagreeable in the mouth, and gave in this case a shock with a
sensation of light before the eyes, as we have found by experimenting
upon ourselves.

From our own most recent experiments, we have ascertained the
following facts, which may guide every horse-owner in the application
of electricity to an animal that is opposed to being shod: (1) To a
horse that defends himself because he is irritable by temperament, and
nervous and impressionable (as happens with animals of pure or nearly
pure blood), the shock must be administered feebly and gradually
before an endeavor is made to take hold of his leg. The horse will
then make a jump, and try to roll over. The jump must be followed,
while an assistant holds the bridle, and the action of the current
must be at once arrested. After this the horse will not endeavor to
defend himself, and his leg may be easily handled.

(2) Certain large, heavy, naturally ugly horses kick through sheer
viciousness. In this case, while the current is being given it should
be gradually increased in intensity, and the horse's foot must be
seized during its action. In most cases the passage of a current
through such horses (whose mucous membrane is less sensitive) produces
only a slightly stupefied and contracted position of the head,
accompanied with a slight tremor. The current must be shut off as soon
as the horse's foot is well in one's hand, and be at once renewed if
he endeavors to defend himself again, as is rarely the case. It is a
mare of this nature that is represented in the annexed figures.

We know that this same system has been applied for bringing to an
