This is a suliject that hasreceived nuich attention ; and most conflictingviews are held concerning it. Although certainof the cerebral nerves at first sight do appear toresemble spinal nerves, both in regard to theirformation and their mode of attachment tothe brain, is of opinion that it wouldseem to be wiser, with present knowledge, tobe careful not to push the comparison too far,and for the most part to be content to considerthe cerebral nerves by themselves. and the mostrecent papersof Gushing onthis subjectprobably givethe most ac-curate picturesas yet availableof the sensorydistribution ofthis greatnerve, both onthe face, andin the mouth,nose, and pharynx. It is most satisfactory tonote that as regards the surface of the face. Kic. 519.—Cutaneous distribution of the trigeminalnerve in man as determined by Gushing. Over thedotted areas sensation was not completely lost,but painful sensations were interpreted as tactilesensations. (After Professor Di-xon.) and head, the minute anatomical dissections ofFrohse enabled him quite accurately tomap out the sensory field of the trigeminal nerve ; 449 and Gushing remarks that the outline given inone of Frohses figures is practically the counter- ipart of the skhi-field demarcated in nearly allhis cases of trigemuial neurectomy. A consideration of these facts sliows thatthere is a close analogy between the trigeminaland a segmental nerve. The trigemmal nerve isdistributed to the internal organs of the mouth—?teeth, tongue, etc., and sends branches to supplythe skin and the face; so that in cases ofneuralgia or referred paui it might naturallybe expected that the areas of tenderness tracedout by Head would be fo
