DESCRIPTION OF PLATE II, 
Illustrating Dr. Beale’s Paper on the Minute Anatomy of 
the Papillae of the Frog’s Tongue. 
Fig. 
3. — Portion of the central stem of nerve-fibres, breaking up to form the 
nerve plexus at the top of papilla, 'a. Epithelium -like cells near the 
summit of the papilla, b. Intricate interlacement of finest nerve- 
fibres immediately below, highly magnified at c, fig. 2. c. Expan- 
sion of nerve-fibres in the form of a network on the top of the 
papilla, x 1700. 
4. — Diagram to show the supposed arrangement of the nerves, and their 
connection with the cells on the summit of the papilla. 
5. — A portion of one of the triangular cells or nuclei connected with the 
fine nerve-fibres, forming the plexus at the top of the papilla, as seen 
after the removal of the epithelium-like mass from the summit. The 
fine fibres upon the surface are those which pass to the epithelium- 
like mass on the summit. X 6000. 
6. — Three cells from the epithelium-like mass upon the summit of the 
papilla, x 2000. 
7. — Free surface of the cells of the epithelium-like mass at the summit of 
the papilla. X 2000. 
8. — Fine nerve-fibres coming off from a trunk, to be distributed to muscles, 
vessels, and connective tissue, near the base of a papilla, as at f, fig. 
1. X 1800. 
9. — Muscular fibres at the summit of the papilla, showing the relation of 
the germinal matter to the contractile tissue, and the mode of forma- 
tion of the latter by the masses of germinal matter, a. Germinal 
matter, or nucleus forming fibrillse. 6. Another nucleus, or mass of 
germinal matter, connected with muscular tissue, c. Germinal mat- 
ter, or nucleus of fine nerve-fibre, distributed to the muscle near the 
summit of the papilla, d. Fine nerve-fibre. X 1800.
