In studying normal or pathologic peripheral nerves, one is confronted with a number of uncertainties, if not riddles, pertaining to both their normal and their pathologic histology. For instance, no definite information is available as to what actually makes up a normal peripheral nerve or how to interpret some phenomena occurring in such common conditions as peripheral nerve degeneration or regeneration. A discussion of some such problems is the object of this contribution. The observations here recorded have been made on the instructive material placed at my disposal by Spielmeyer (Munich), Nageotte (Paris) and Ranson (Chicago), but these gentlemen, of course, are not responsible for the views here advocated. The human material of Professor Spielmeyer—180 war cases, only a part of which I studied— was, like the rich experimental material of Nageotte and Ranson, ready for microscopic study. Though there are some disadvantages in using ready material, since additional, especially
