From this it would seem that we are here concerned essentially with local changes in the muscle, confined to the immediate proximity of the physiological anode or kathode, and not, as in cardiac muscle, extending over a larger area. The changes of form described above in the sartorius, thrown by veratriii into an artificial state " analogous to tonus," present a complete analogy with the consequences of electrical excitation in systolically-contracted cardiac muscle, as above described. Here, too, along with the ordinary effects of polar excitation (which for the rest appear less
