It is customary, during the hysteric fit or paroxysm, to bleed the patient.

485. The first law of motion may be stated thus. If no force act upon a body, it will, if at rest, remain for ever at rest ; or if in motion, it will continue for ever to move with a uniform velocity. We know this law to be true, and yet no one has ever seen it to be true for the simple reason that we cannot realise th... |
