dant on those nerves near the ganglia from which they proceed, 

 and in the ganglia themselves. These bodies, with the nuclei of 

 capillary vessels and those of fat vesicles, and probably other struc- 

 tures with peculiar cells, which alone deserve the name, have been 

 included under the term " areolar tissue corpuscles " (Bindegewebe- 

 korperchen). As specimens are usually prepared, it is quite impos- 

 sible to distinguish these structures from each other. It is pro- 

 bable that the gelatinous fibres, or fibres of Remak, are after all real 

 nerve-fibres, and not a peculiar modification of fibrous tissue, as is 

 now generally believed. 



The nerves and vessels, and with them, of course, the oval bodies, 

 may be stripped off from the elementary muscular fibre. They are 

 in close contact with the sarcolemma; and the author has been led to 

 conclude from some appearances he has observed, that this structure 

 is really composed of capillaries and nerve-fibres, with intervening 

 tissue. 



Of the manner in which nerves terminate. The fibres connecting 

 the oval bodies or nuclei form with them a network, the branches 

 of which are of course continuous with the subdivisions of the nerve- 

 fibres. The arrangement of the network, and especially the number 

 and proximity of the nuclei to each other, differ materially in dif- 

 ferent localities. On sentient surfaces the meshes are very small 

 and the nuclei close together ; but from the complexity and great 

 number of the fibres, from the fact that many fibres which appear 

 to be single can be resolved into three or four individual fibres, and 

 from the circumstance of the network being imbedded, in most cases, 

 in the midst of fibrous tissue, it is very difficult to describe its exact 

 relations and disposition. However, from the connexions of this 

 network with the nerve-fibres, it would seem to follow that an im- 

 pression made upon a given portion of a sentient surface might be 

 transmitted to the nervous centre by contiguous fibres, as well as by 

 the one which would form, so to say, the shortest route ; and it is 

 possible that impulses to motion may be conveyed to muscular fibres 

 by a more or less circuitous path, as well as by a direct one. 



Of the so-called tubular membrane. This is a transparent struc- 

 ture in which the nerve-fibres are imbedded. It cannot strictly be 

 called a membrane, because in many cases several fibres are im- 

 bedded in it, and often it is much thicker than the fibres it contains.
