74 OF THE CELLULAR SYSTEM. 



Where the skin yields least, as on the head, tibia, and ster- 

 num, cicatrices are largest. 



Q. How does union by the first intention differ from 

 cicatrization ? 



#. In the union, the periods and processes of cicatriza- 

 tion do not appear: the union is by an agglutination of the 

 sides of the wound. 



Q. By what property do cicatrices contract ? 



#. By organic contractility in the cellular vesicles. 



Q. What is fungous flesh ? 



#. Exuberant formations of cellular vesicles in wounds 

 and ulcers. 



Q. Whence and what are polypi? 



#. These and all other excrescences arise from a mor- 

 bid reproductive effort, or spontaneous elongation of the 

 cellular texture. 



Q. How do you account for the differences in tumours? 



t#. They arise from the variety of deposites made in 

 the elongated cellular texture. 



Q. Is there no way to account for this variety in the 

 deposites ? 



*#. It depends on the degree of the vital forces in the 

 elongated textures; a higher exercise of these forces pro- 

 ducing one deposite, a lower another. 



Q. But are there not tumours independent of this elon- 

 gating action of the cellular texture ? 



A. Yes; those of a chronic character, from infiltration 

 of the cellular texture. 



Q. What is a cyst? 



A. A membranous sac without opening, developed ac- 

 cidentally; cysts contain fluids of different sorts. 



Q. What texture forms them ?
