power of attracting hypnotised subjects. Thus, if a
good-sized magnet is placed at some little distance from the subject,
and behind a screen so that he cannot see it, after a time he will
get up and go towards it. If now another magnet be placed at an equal
distance behind him, he will stop and remain as it were balanced
between the two. By withdrawing one or other he can be drawn
backwards or forwards. Further, he can be charged with magnetism by
placing near him a large magnet with five ends. If it be suddenly
removed and hidden in another room, he is impelled to follow it with
such force that he will fling aside all obstacles in his way, and
tracking it step by step will walk straight up to it. 'Once he sights
it, he either remains in dumb contemplation of it in front of its two
poles, or else lays his hands on both of the poles with a kind of
profound satisfaction.' These experiments with magnets are very
exhausting.

Finally, if the senses can be so heightened as in the cases already
cited from Braid and the clinique of La Salpetriere, it requires no
great stretch of imagination to suppose them carried still further
until they become comparable to those inexplicable faculties which we
call instinct in animals, that for instance by which animals--cats,
dogs, and sheep--can find their way home, sometimes over hundreds of
miles of unknown country.

Concerning the faculty of presensation, it is worth while to say a
little more. The early mesmerists made a great point of the power of
some patients to diagnose the condition of another. Dr. Puysegur's
patient Joly, mentioned above, possessed the faculty to an unusual
degree. He was an educated man, of good position, and could express
himself intelligibly:--

C'est une sensation veritable que j'eprouve dans un endroit
correspondant a la partie qui souffre chez celui que je touche: ma
main va naturellement se porter a l'endroit de son mal, et je ne peux
pas plus m'y tromper que je ne pourrois le faire en portant ma main
ou je souffrirois moi-meme.

Now, the following experiment has been carried out by Charcot at La
Salpetriere. A young girl suffering from hysterical hemiplegia
(paralysis of one side) came up one day from the country. She was
placed in a chair behind a screen and a hypnotic patient sent for
from the wards. The latter was placed on the other side of the screen
and hypnotised. Neither of the patients was aware of
