Abstract

I will present to the Section the result of my work in the line of the subject given which I think is of value, since it enables one easily and expeditiously to locate any part of the surface or internal structure definitely, and with a precision that can be arrived at in no other way. I have hardened a brain with great care so as to maintain the natural shape as nearly as possible. The lateral halves were separated in the median line and each embedded in tallow, taking care to place each half in the same positions in the boxes surrounding them. Each half was carefully sliced by a gauge so that the slices were three-sixteenths of an inch thick and perpendicular to a line in the long axis of the brain, which was seven inches in length, making thus thirty-seven slices of each ganglion. The right, ganglion was
