Although, as a rule, but the symptom of some definite pathological condition, agrypnia is of such frequent occurrence, and so detrimental to the general health, that it appears to me to merit special consideration. This holds good especially in this connection, because, even where electric baths fail to influence the disease giving rise to the insomnia, they almost invariably remove this, irrespective of its cause. Even where, the disease itself remaining uncured, the insomnia must return sooner or later, the sleep is very much improved while the baths are being had recourse to. We must of course endeavor in all cases to relieve the original disease, and, where the baths are not adapted to this purpose, resort to other and appropriate means. It will be found of no small service to us in the therapeutical management of every case, to be enabled to procure for the patient, without the aid of medicinal hypnotics, sufficient of sleep during treatment. CASE XIII. Mr. A., from the _clientele_ of Dr. LEONARD WEBER, was sent by Dr. W. to take electric baths. He suffered from chronic spinal congestion. Among the most prominent and annoying symptoms was _agrypnia_. It was for the relief of this symptom chiefly that Dr. W. ordered him the baths. He began to improve in this respect from the time he took his first bath, and although the disease itself remained uncured, he enjoyed good sound sleep while he was under treatment, his general health improved, and he frequently spoke of the notable benefits that he received from the baths. He continued them until his departure for Europe, where, by direction of his physician, he went last spring. I have not seen him since, but Dr. W. tells me that he is doing well. CASE XIV. Mr. D. was brought on Sept. 30th, 1874, by his physician, Dr. HOGAN. He was in the incipient stage of _delirium tremens_. Had not slept for some nights. Dr. H. had administered successively opiates, chloral and bromides in full doses, without effect. On the evening of above date the patient had a bath, in which the descending galvanic current was used. As a result, he slept well that night. The baths were repeated on the two succeeding days, with like effect. As the disease developed however it became necessary to send the patient to an asylum, whence he returned cured in a short time. The effect of the baths in this case, where full doses of the most powerful hypnotics of the materia medica had failed, was remarkably illustrative of their hypnotic power. ANÆMIA.
