1. Motilities and sensitivities to the acetylcholine, adrenaline and barium chloride of isolated vasa deferentia of rats, mice, guinea-pigs, rabbits, dogs, cats and goats were studied in usual way by the Magnus method. 2. Spontaneous movements of the vasa deferentia were observed in three out of the twelve guinea-pigs, all five rabbits, two of the three goats and one cat, but not in the other preparations. 3. The sensitivity of the vasa deferentia of guinea-pigs, rabbits and goats to acetylcholine was higher than that of the others and followed by mice and rats in the order. The organs of dogs seemed to be less sensitive to acetylcholine. 4. Differences in sensitivity to adrenaline were not clear among the species examined, except the preparations of goats. Only the preparations of the goat seemed to be more sensitive than those of the other species. 5. The sensitivity to barium chloride showed a similar tendency to that to acetylcholine, though it was not so conspicuous as in the results with acetylcholine. 6. A possible relationship between the difference of ejaculation types among animal species and the motility of isolated vasa deferentia, especially the sensitivity to acetylcholine, was suggested.
