outside to outside is made to measure about five feet ten inches, the back-rest fitted in at a proper slant will bring the inside of the tub to about the right length for an average male adult. All around the upper edge of the tub runs a wooden coping, which must not be fastened down however until all the attachments for conducting the current are in situ. Along that portion of the top of the tub where required-and this will depend on the situation of the binding posts presently to be mentioned-and u

e dimensions of these receptacles must of course correspond to those of the carbon plates to be employed as electrodes. Those which I use measure 12×8″ at the head, 8×6″ at the foot of the tub. They are ?″ thick. T

ically shorten the tub and adapt it to persons of different lengths. This board may conveniently be six inches wide, and should have a number of perforations about an inch in diameter, for the transmission of the current to the

d be of the kind known as "single" binding posts with "wood screws." The most convenient location for them will be found on the coping covering the horizontal portion at the head of the tub. Here the copin

ead of the tub-which should now be placed in position-and about two inches apart, the posts a

e made half an inch outwards from the centre of the site of each binding post. The best wire to use is about No. 16 copper wire, coated with gutta percha or rubber. The site of the posts being as above suggested, it will be found that the wire which is to connect the head electrode with one post requires to be about 18 inches long, that which runs from the other post to the foot-electrode

dge of this side to the head of the tub, and thence to the respective gimlet hole, and through this, from within outward. The wires being now all in position, all the coping is next screwed or nailed down firmly, care being taken that the screws or nails used for this purpose do not injure any of the wires. The coping fastened down, the binding posts are now screwed down in the sites previously marked out for them. Before they are screwed entirely down, the denuded portion of the proximal end of each wire is securely wound around the screw of the respective binding post, and the posts are then firmly screwed down
