1. It is demonstrated whith a new “glycerine spot method” (1952, Kotsuka) and a mechanical stimulation method that efferent glossopharyngeal vasodilator nerves exist in a frog's tongue.
2. Atropinized blood vessels in a frog's tongue are constricted when the cut peripheral end of glossopharyngeal nerves is stimulated with “glycerine spot method” and mechanical stimulation method. It is evidenced that there exist efferent glossopharyngeal vasoconstricting nerves in a frog's tongue.
3. The above findings demonstrate that blood vessels of frog's tongue are subject to a vasodilatation and vasoconstriction action of glossopharyngeal nerves i. e., glossopharyngeal double innervation action.
