EXPLANATION OF PLATE XXII, 
Illustrating Mr. McCarthy’s Remarks on Spinal Ganglia 
and Nerve-Fibres. 
¥ies. I and II represent two of the larger ganglion-cells 
Fic. 
Fig. 
a. Fibrous capsule, with nuclei of connective-tissue corpuscles. 
6. Nucleated hyaline layer, showing the various arrangements of the 
nuclei, some of which appear to be undergoing, or to have recently 
undergone subdivision. c¢. Molecular matter, granular externally, 
fibrillated internally. dd. Pigment-granules, x. Nucleus. zs. Nu- 
cleolus. 
I1].—Transverse section of a small bundle of nerve-fibres which lay 
outside the main nerve-trunk at a little distance beyond the 
ganglion 
c. Nucleated fibrous perineurium. /. Lymphatic sheath, with en- 
dothelial lining. e. Endoneurium of Axel Key and Retzius.  Nerve- 
fibres with sheath of Schwann in parts nucleated, and with rod-like 
striation of medullary sheath, the arrangement varying as described 
in text. (Only some fibres have been represented for the sake of clear- 
ness.) 
IV.—Two nerve-fibres cut longitudinally. 
a. Nucleated sheath of Schwann. ce. Ranvier’s constrictions. 7. Rod- 
like striation of medullary sheath seen in profile. s. Seen from the 
surface. a. Axis cylinder. 
Norz.—In Figs. I, II the separation between the limiting membrane and 
body of the ganglion-cell is exaggerated; such separation is neither con- 
stant nor complete, and when present appears to me to be artificial and the 
result of the reagents employed.
