Dr. Mott gave a demonstration by means of lantern slides and microscopical specimens to illustrate “some points concerning the degeneration of the neuron.”

He pointed out that the “neuron” must be considered as a very complex cell with processes, of which, as Golgi had maintained, one is the neuraxon or axis cylinder process, the others dendrons. The dendrons receive the impulse which, passing through the cell, is conveyed to the neuraxon. Every neuron is an independent protoplasmic unit, anatomically distinct, in contiguity with other neurons, but not in continuity.
