It is well to increasethe size of the electrodes proportionately tothe strength of the current employed. Fig. 191 illustrates the effect of separationof the poles when applications of electricityare made to the spinal column. Some of tliethreads of current depicted are rendered in-effjective on account of their diffusion. Thisis made more apparent in Fig. Fig. 192—A Schematic Repre-sentation OP THE Density of THE CUKRENT UPON APPLICATION OP THE Electrodes to the SameSurface and in Close RelationTO each other.

To treat properly of the various methodswhich may be used when the application ofelectrical ciurents as a therapeutical measurefor the relief of spinal diseases seems indicated,it would be necessary for me to enter intogreater detail regarding s])inal diseases thanthe space allotted to these lectures will perjiiitof. I am reluctantly forced, therefore, tosummarize somewhat hastily the main pointswhich my experience with this agent leads meto indorse. Most of my readers are probablyalready familiar with the pathological changes which exist in connectionwith the more common diseases of the cord ; but, if any are not so, thesechanges should first be studied and
