DESCRIPTION OF PLATE IV, 
Illustrating Dr. Beale’s Paper on the Minute Anatomy of 
the Papillae of the Frog’s Tongue. 
Pig- 
16. — Mode of formation of network or plexus of finest nerve-fibres. 
17. — Mode in which a single nerve-fibre is supposed to terminate, according 
to most authors. 
18. — The author’s view of the arrangement of the nerve-fibres and formation 
of the terminal plexus or network of fine nerve-fibres. 
19. — Arrangement of terminal pale nucleated nerve-fibres in simple papillse. 
20. — Division of dark-bordered nerve-fibres, with fine fibres ramifying in the 
sheath. Breast muscle, frog. X 300. 
21 & 22. — Diagrams to illustrate the course of the nerve-fibres iu a branch, a, 
coming off from a larger trunk, b b. 
23. — Fine compound nerve-trunk, with a branch coming off at right angles, 
composed of fibres which pursue opposite courses in the trunk. 
From the submucous tissue of the palate. Frog. X 700. 1862. 
24. — A copy of Hartmann’s figure referred to in page 3, showing the 
nerves in the centre of the papilla, which, according to him, termi- 
nate abruptly. The nerves have been much altered by the method 
of preparation pursued, and the finer branches are invisible.
