    same agency as the cautery, and both are but better appUcations of a principle well known to our grand- mothers—that a cold key placed on the upper part of the spine soon arrests an ordinary nasal haemorrhage. 7th. The galvanic current of low tension applied to the nucha and the head, and repeated every day or every alternate day for five minutes, as the case may require, is of great benefit. One pole should be placed at the very summit of the spine and the other some three or four inches below it. I have repeat- edly seen, as I stated several years ago * the arteries of the retina contract while the current was passing in this way—an indication that a like influence was exerted on the intra-cranial vessels. A similar effect is caused by passing the current directly through the brain, the poles being applied to the mastoid processes. A slight feeling of vertigo is experienced both when the circuit is closed and opened. Care should be taken that the current is not too intense. Such is the medical treatment which I have found most generally serviceable in the treatment of cerebral hyperaemia during what may be called its acute stage. But occasionally we meet with cases in which the bromides are not well borne, and again, others in which ergot causes gastric and intestinal irritation. * Spinal Irritation.—^Journal of Psychological Medicine.
