1st. _A full_, _slow_, and _regular_ pulse, denotes a perfect state of health; for whilst the blood moves regularly in the arteries, without pain to the nervous system, or disturbance to the animal œconomy, the pulse will beat precisely regular, without trembling, fluttering, hurry, distinction, or feebleness, and discover to the touch, a peculiar easiness; and this, every one, who wishes to become master of that subject, should carefully attend to. 2dly. _A full_ and _quick pulse_, indicates a fever; for by the irritation of the nerves, the vibration of the arteries are accelerated. If a gentle perspiration attends it, it may be deemed salutary; and with this pulse it appears, that nature makes a vigorous effort to expel what is obnoxious: therefore in such a pulse, a gentle perspiration generally gives relief. 3dly. _A full_, _quick_, and _hard pulse_, denotes great irritability in the nerves, and a redundancy of blood; this is the pulse of a fever; and here bleeding, if timely applied, is very requisite, as also medicines which promote perspiration. 4thly. _A small_ and _quick pulse_, denotes an irritability in the nervous system, and a contraction of the arteries; this is generally the pulse which attends sudden shocks and frights, as also in the cold fits of agues. The causes should carefully be attended to: if, from a sudden shock, bleeding is useful; but in the latter case, it is hurtful. It seldom lasts long, and a full feverish pulse generally follows, and the state of the patient ought here to be the guide: for, the same pulse may proceed from too great a plenty of blood, as well as from a deficiency; consequently requires different treatment; and this shall be pointed out more fully hereafter. 5thly. _An irregular full pulse_, is at all times a bad one; many may be the causes, and generally denotes a great confusion in the nervous system, and in the circulation of the blood. This pulse is generally the attendant on violent inflammations, phrenzy, delirium, &c. and if it continues any time, forebodes great danger: bleeding in time is greatly requisite, and other remedies, in order to assist the nerves, and bring the circulation to its proper regulation again. 6thly. _An irregular small pulse_, is frequently the attendant of an emaciated constitution, putrid fevers, and consumptions; and this dangerous pulse too generally forebodes the approach of death. The more irregular the pulse grows, _small_, _weak_, _trembling_, and leaves off by irregular intervals, the sooner dissolution is at hand; till at last, the pulse entirely disappears, and life ceases. But dangerous as this pulse is, yet it must be observed, that it often appears in the strongest constitutions, as in sudden emotions of the mind, falls, &c. or in a swooning. This is also the last and the first pulse in suffocations; or in other words, the struggling pulse between life and death.
