close to the surface. Their proper seat is the mucous layer, 
hut they frequently project into the horny epithelial coat. 
The processes directed inwards from each vesicle are direct 
continuations of the nerves, the axis cylinders of which 
pass into the interior of the vesicle and there ramify. Each 
branch terminates in a prismatic body, which is placed on a 
short pedicle. The vesicle itself is filled with a colourless 
and slightly granular fluid, and its outer surface is marked 
with fine sti'eaks, which, according to Letzerich, are sug- 
gestive of epithelial cells, and indicate the history of the 
development of the bodies. This probably consists in a fusion of 
several epithelial cells, in which the nerves are continued, 
and terminate in the manner described. The processes which 
pass outwards from the surface of each vesicle are lost in the 
horny epithelium. 
On the Terminal Apparatus of Motor Nerves. "NV. 
Krause. Archiv v. Ileichert and du Bois-JReymond, 1868. 
— A description is here given of the terminal enlargements 
of motor nerves. These bodies are elongated in the pike and 
in frogs, of an oval shape in chelonian reptiles, and rounded 
in other reptiles, and in birds and mammals. In the frog 
each primitive muscular bundle is furnished with a single 
terminal body, over which passes either one large nerve- 
fibre, or two or three short branches of one fibre. These 
nerve-fibres break up again into several small terminal 
branches, which are lost in the granulated and nucleated 
substance of the terminal body. Each of these minute 
branches bears a rounded terminal swelling. According 
to Krause, nearly the whole of the granular substance of the 
terminal bodies appears under the microscope to be made up 
of the finest terminal divisions of motor nerves. 
On the Nerves of the Shin. P. Langerhaus. Virchow’s 
Archiv, bd. xliv, 1868. — In this contribution a description 
is given of the ultimate ramifications and terminations of 
the nerve-fibres distributed to the superficial layers of the 
integument, and to the hair follicles and sudoriferous ducts. 
The following statements are given by Langerhaus as to the 
results of investigations made on sections of human integu- 
ment treated by solutions of chloride of gold. The deeper 
parts of the dermis are traversed by ramifications formed by 
numerous small nerve-fibres without tendons, and in regions 
supplied with touch-bodies, as in the hands and feet, by 
several true doubly-contoured nerves. At the superior surface 
of the dermis these fibres pass into a very close rectilineal 
network made up of nerve filaments, which are extremely 
small, of a pale red colour, and freely nucleated. From this
