THE SKIN AND ITS ADNEXA. 233 



character in different parts of the body. From 

 these, certain medullated nerves pass into the papillae 

 and terminate in the tactile corpuscles (called Meiss- 

 ner's corpuscles) ; others pass to the hair-follicles 

 and sebaceous glands; still other, non-medullated 

 nerves enter the papillae or pass between the cells 

 of the rete Malpighi, but their mode of termination 

 is not yet definitely ascertained. The structure of 

 the Pacinian bodies and Meissner's corpuscles is too 

 intricate, and the methods required for their com- 

 plete demonstration too elaborate, to justify their 

 further consideration here. 



TECHNIQUE. 



Sections of Skin. A piece of skin is removed from 

 a recently amputated arm or leg, care being taken to in- 

 clude the subcutaneous tissue to a considerable depth ; 

 it is stretched flat on a bit of sheet cork, and placed in 

 Mtiller's fluid for ten days, it is then washed well in 

 water and placed in strong alcohol. When sufficiently 

 hard bits are imbedded in celloidin, and sections made 

 perpendicular to the surface ; these are stained double 

 and mounted in balsam. 



Sections of Injected Skin. A piece of skin from an in- 

 jected arm or leg is stretched on a bit of sheet cork, as 

 above, and hardened in alcohol. Sections are stained in 

 eosin and mounted in balsam. 



Sections of Skin of Negro. The skin is hardened in 

 Miiller's fluid, the sections stained with eosin and 

 mounted in balsam.
