The present study was undertaken to examine the latent labyrinthine reflex and sensation to the linear acceleration in the human body and following results were obtained.1)A close relationship was recognized between the latent progressive reflex observed by electromyography in the human body, and the results obtained by the usual vestibular examination. 2) In the reflex to the linear acceleration, the frequency of its appearance was varied by altering the head position in the movement of the ups and downs on the frontal axis, but it was hardly varied by altering the head position right and left on the sgittal axis.3) As a result of the experiment in the human body, the sensitivity of the linear kinetic sensation in the vertical direction was found to be varied by lineal acceleration closed to the threshold of kinetic sensation, when the head posititon was altered on the frontal axis. 4) The results of these experiments indicated that the saccles otlith mainly acted for receiving the movement to the right and the left, while utricles otolith served to receive that to the upward and the downward, but both otoliths seemed to act mutually with duplicate or subsidiary function.5) The observation of the linear kinetic reflex might be applied in the clinical field of medicine as one of the test of vestibular function of human bodies. 6) In the experiment on rabbit, the labyrinthine muscle reflex to the linear acceleration was mainly observed to appeare in the flexor muscles of the extremities contralaterally. 7) The appearance of this reflex did not always require interposition of the cervical muscles.
