Owing to the treat- ment with paraffine, the floor is water-proof, and, therefore, is easily kept clean. And being of cork, pins may be readily thrust into it to hold the frog. Three pairs of electrode holders w-ith adjustable electrodes are mounted along either side. The holders are so spaced that the gastroc- nemius muscle, sciatic nerve, and fore limb skin or nerves may be stimulated. Or all three pairs may be adjusted to the sciatic, as in studying the local action of reagents on the nerve trunk. A tubular metal container is provided for the electrodes when not in use. A special multiple key and switch serve to control the current to the.
