In examining sections from three human medullas (in two of whichthe series was complete) I find in all a small, round, compact collectionof cells, lateral to the fasciculus solitarius, in nearly the same relativeposition as the cells just described in the dog. In man this clump ofcells is first met at a level somewhat higher than tliat described above E.
