After the tissue has been properly stained, which is known 

 when it has taken a mauve or violet tint, as already stated, the 

 specimen should be allowed to stand in the sun. Thin lamel- 

 lae are then torn off with the forceps and mounted in dammar 

 varnish or Canada balsam. 



After the specimen has been made thoroughly transparent 

 by soaking in oil of cloves, it will then be seen that there are 

 bodies within certain well-defined areas the corneal spaces,

as they have been called by Recklinghausen and others. These 

 bodies are disposed at quite regular intervals throughout the 

 cornea, and are generally flat with rounded contours, though 

 often they have processes extending from them in various direc- 

 tions. In the accompanying drawing the spaces may be dis- 

 tinctly seen, as well as the variously shaped corneal corpuscles. 

 One, c, is crowded into the prolongation of a corneal space, 

 while another, 5, is connected by its processes with a neighbor- 

 ing corpuscle. One corneal space, a, is entirely empty. These 

 differing conditions are in a measure due, probably, to the
