he word as it came to him in a quick, sharp voice, at the same
time he jumped, or struck, or threw, or raised his shoulders, or made
some other violent muscular motion. They could not help repeating the
word or sound that came from the person that ordered them, any more
than they could help striking, dropping, throwing, jumping, or
starting; all of these phenomena were indeed but parts of the general
condition known as jumping. It was not necessary that the sound should
come from a human being; any sudden or unexpected noise, as the
explosion of a gun or pistol, the falling of a window, or the slamming
of a door--provided it was unexpected and loud enough--would cause
these jumpers to exhibit some one or all of these phenomena. One of
these jumpers came very near cutting his throat, while shaving, on
hearing a door slam. They had been known to strike their fists against a
red-hot stove, to jump into the fire and into water. They could not
help striking their best friend if near them when ordered. The noise
of a steam whistle was especially obnoxious to them. One of these
jumpers, when taking some bromide of sodium in a tumbler, was told to
throw it, and he dashed the tumbler upon the floor. It was dangerous
to startle them in any way when they had an ax or an knife in their
hands. All of the jumpers agreed that it tired them to be jumped, and
they dreaded it, but they were constantly annoyed by their companions.
From this description it will at once, I think, be perceived that
there are striking analogies between "miryachit" and this disorder of
the "Jumping Frenchmen" of Maine. Indeed, it appears to me that, if
the two affections were carefully studied, it would be found that they
were identical, or that, at any rate, the phenomena of the one could
readily be developed into those of the others. It is not stated that
the subjects of miryachit do what they are told to do. They require an
example to reach their brains through the sense of sight or that of
hearing, whereas the "Jumpers" do not apparently perform an act which
is executed before them, but they require a command. It seems,
however, that a "Jumper" starts whenever any sudden noise reaches his
ears.
In both classes of cases a suggestion of some kind is required, and
then the act takes place independently of the will. There is another
analogous condition known by the Germans as _Schlaftrunkenheit_, and
to English and American neurologists as somnolentia, or
