Whereas the stimula-tion of vibratory massage is limited to the nerve ter-minals, or, at most, to the nerve fibres, an electricalcurrent stimulates the nerve centres also. In the application of the sinusoidal current tothe eyes, I use the same electrodes as when treatingwith the direct current.

THE EELATION OF MAGNETISM TO THEEAPEUTICS. The concensus of opinion is that magnetism hasno perceptible effect upon the organism. I extractthe following from Scheppegrell:—The effects ofmagnetism in therapeutics have been investigated byPeterson and Kennelly, who have, recently, tried itwith an exceedingly strong field, and have come to theconclusion that the human organism is in no way,appreciably, atfected by the most powerful magnetsknown to science. A. E. Dolbear, of Boston, how-ever, holds that it is not proved that magnetism iswithout any effect on the human body, but believesthat the experiments, which have been made, simplyshow that magnetism, unlike electricity, does not pro-duce the mechanical and chemical changes necessaryto be appreciated by the subject. Personally, I cannot believe that it will not yetbe demonstrate
