The heart was made to beat, and many men of eminence supposed that if
this could be combined with artificial respiration, and kept up for
awhile, the victim of the hangman might be restored, provided the neck
was not broken. Curious tales were loudly whispered concerning gentle
hangings and strange doings at Dr. Brookes's, in Leicester Square, and
at the Hunterian Museum, in Windmill Street, now flourishing as "The
Café de l'Etoile." When a child, I lived about midway between these
celebrated schools of practical anatomy, and well remember the tales of
horror that were recounted concerning them. When Bishop and Williams (no
relation to the writer) were hanged for burking, i.e., murdering people
in order to provide "subjects" for dissection, their bodies were sent to
Windmill Street, and the popular notion was that, being old and faithful
servants of the doctors, they were galvanized to life, and again set up
in their old business.
It is amusing to read some of the treatises on medical galvanism that
were published at about this period, and contrast their positive
statements of cures effected and results anticipated with the position
now attained by electricity as a curative agent.
Then came the brilliant discoveries of Faraday, Ampère, etc.,
demonstrating the relations between electricity and magnetism, and
immediately following them a multitude of patents for electro-motors,
and wild dreams of superseding steam-engines by magneto-electric
machinery.
The following, which I copy from the _Penny Mechanic_, of June 10, 1837,
is curious, and very instructive to those who think of investing in any
of the electric power companies of to-day: "Mr. Thomas Davenport, a
Vermont blacksmith, has discovered a mode of applying magnetic and
electro-magnetic power, which we have good ground for believing will be
of immense importance to the world." This announcement is followed by
reference to Professor Silliman's _American Journal of Science and the
Arts_, for April, 1837, and extracts from American papers, of which the
following is a specimen: "1. We saw a small cylindrical battery, about
nine inches in length, three or four in diameter, produce a magnetic
power of about 300 lb., and which, therefore, we could not move with
our utmost strength. 2. We saw a small wheel, five-and-a-half inches in
diameter, performing more than 600 revolutions in a minute, and lift a
weight of 24 lb. one foot per minute, from the power of a battery of
still smaller dimensions. 3. We saw a model of a locomotive engine
traveling on a circular railroad with immense velocity, and rapidly
ascending an inclined plane of far greater elevation than any hitherto
ascended by steam-power. And these and various other experiments which
we saw, convinced us of the truth of the opinion expressed by Professors
Silliman, Renwick, and others, that the power of machinery may be
increased from this source beyond any assignable limit. It is computed
