Cartilage. 69 



a serous membrane, forming the greater part of the 

 framework. 



White fibrous tissue is also well seen in sections of 

 skin ; also in submucous tissues. 



ADIPOSE TISSUE. 



Well seen in some of the preparations of serous 

 membrane, when the fat cells lie thickly along the sides 

 of the blood vessels. Also seen in cutis vera, and in 

 many other parts. It is not necessary to make a spe- 

 cial preparation of it. 



A serous membrane placed for a short time in dilute 

 osmic acid, and mounted in glycerine, will show the fat 

 cells differentiated from the surrounding tissue, as they 

 have all become blackened by the action of the osmic 

 acid. 



CAETILAGE. 

 HYALINE CARTILAGE. 



The thin cartilaginous expansions from the sternum 

 of the newt, prepared by the gold process, make very 

 good specimens of hyaline cartilage. Thin sections 

 may be cut by the microtome, or by hand. In this 

 preparation the lymph canals will be seen looking like 

 dark processes proceeding from the lacuna, in which 

 the cell lies, into the hyaline matrix. 



Sections of the nasal cartilages of small animals, 

 growing bone, &c., will all give good examples of hya- 

 line cartilage. 



In the fresh state the cells will be seen to fill the
