_Treatment._—Before proceeding to the mode of treatment, the following objects are to be strictly borne in mind:—1. To gain a perfect command over the maniac. 2. To divert the patient’s mind from the existing train of thought. 3. To diminish the preternatural action of the brain. To effect these results, the following remedies must be had recourse to:—1. By bleeding, if of a plethoric habit, and the attack recent. 2. Purgatives; both the drastic and cooling aperiatives have been recommended—perhaps the former are preferable; hellebore, senna, and jalap. 3. A spare low diet. 4. Emetics of sulphate of zinc, or of tartar emetic. 5. Nauseating remedies. 6. Cold bath during the paroxysms. 7. Sedatives; hemlock, camphor, and henbane; opium is generally prejudicial. 8. Counter-irritants; blisters, setons or issues. 9. Where great debility is present from the first, or supervenes after the employment of active remedies, tonics and stimulants, as in debility from other causes. Insanity, to a greater or less extent, may be regarded as an effect of many fevers, especially those of nervous order and typhoid type, and though in general the hallucinations of this mental disturbance subside on the decadence of the symptoms, cases arise where the balance of mental power is not restored for some considerable time after the bodily recovery, and others in which a predisposition is left behind, upon which, at the slightest excitement, the insanity returns with perhaps increased severity; in such cases the disease assumes a new phase, and more properly comes under the denomination of lunacy. HYDROPHOBIA. Hydrophobia, or dread of water, as the name signifies, is a disease peculiarly affecting the nervous system, caused by the bite and absorption into the blood of the saliva, or _virus_, as it is called, of some rabid or strongly irritated animal, but most frequently of the two domestic species, the dog and cat, though, from the almost analogous symptoms excited in the system by certain accidents, eventuating in what has been called _tetanus_, the two diseases by many medical men have been considered as synonymous. The influence exerted by the mind on the body, both for good and evil, is a fact well known to the most casual observer, but in no instance is that effect exercised with more dangerous consequences than in the disease under notice; for it is unquestioned that many persons have been forced into a state of hydrophobia, simply through the terror inspired by the scratch or abrasion of an animal perfectly in health, though perhaps under a temporary fit of displeasure or pain. The peculiarity of this disease, is the great length of time that usually takes place between the receipt of the accident, or bite, and the disease itself, or the manifestation of the constitutional symptoms; sometimes weeks elapse, at others months, and not unfrequently years have supervened between the cause and the effect.
