The topical use of cold is beneficial in this condition for the same reasons precisely as in inflammation. in vascular irritation or active congestion of the brain, it is almost indispensable. This condition exists frequently in fevers, with or without delirium, and often yields happily to the remedy. Cold water, ice, or snow may be employed, in the manner already indicated; or the water may be allowed to fall in a single stream, or in a shower, by means of a colander, upon the head of the patient, from a foot or two above him, and run off by some convenient arrangement, so as not to wet the remainder of the body, or the bedclothes. The same remedy should be used in all cases of threatened or existing apoplexy, when the face is flushed and the head warm. in convulsions, with the same phenomena, cold water or ice to the head is often highly beneficial, and may not unfrequently be employed with advantage simultaneously with hot pediluvia, or the warm bath. This remark applies to all kinds of convulsion, whether in children or adults, when the head is flushed and heated. in the convulsions of puerperal women, the remedy has been highly commended. in these cases the water first employed should be tepid or about 90° F., and its temperature diminished gradually to 80° F., 70°, or somewhat lower. it should be poured by pailfuls over the head of the patient seated in a bathing tub, or immersed in a tepid bath of about 90°. in severe headaches, which have resisted ordinary measures, the same plan may be employed.

In vascular irritation of the stomach, ice or cold water is not less indicated than in gastritis. in severe vomiting from this cause, it may be used both internally and to the epigastrium. in cardialgia, the drinking of cold water is useful not only by the cold, but also as a simple diluent to weaken the acrimony of the gastric contents.

irritation of the genital organs is often happily treated with cold water. No remedy usually affords more prompt relief in the painful priapism of gonorrhoea, or in the same affection from other causes.
