    [From the Proceedings op the Royal Society, Vol. 44.] Note on some of the Motor Functions of certain Cranial Nerves (V, VII, IX, X, XI, XII), and of the three first Cervical Nerves, in the Monkey (Macacus simcm). By Charles E. Beevor, M.D., F.R.C.P., and Victor Horsley B.S.. F.R.S. (F rom the Laboratory of the Brown Institution). Received May 16, 1888. In the course of an investigation which we are making into the cortical representation of the muscles of the mouth and throat, we have experienced considerable difficulty in describing correctly the movements of these parts, especially when there was any question of bilateral action occurring. On referring to text-books we failed to find any solution of this difficulty, and we therefore determined to make a few observations of the movements evoked by stimulating the several cranial nerves supplying this region in the monkeyj so as to have a definite basis whereon to ground our observations of the movements obtained by stimulating the cortex. In the course of this work we have observed several facts which do not harmonise with the views hitherto generally received. The results are summarised as follows:— Method of Investigation. The foregoing summary of our experiments is based almost entirely upon the results obtained by exciting the respective nerves at the base of the cranial cavity after separating them from the bulb. We have also stimulated the nerves outside the skull in the neck both before and after division. * Towards the expenses of this research a grant was mado by the British Modical Association, on the recommendation of the Scientific Grant Committee of the Association. t Previous observers having employed animals of lowor orders. b
