A PERFECT VACUUM PROVED.

MR. HALSE, the gentleman who has during the last week been lecturing upon

Animal Magnetism, having stated that one of his patients, while under the

magnetic influence, could "see her own inside," the Marquis of

Londonderry, anxious to test the truth of the assertion, requested the

lecturer to operate upon him, and being thrown into the Mesmeric sleep,

looked into the inside of his own head, and declared he could see nothing

in it.
