FIBRO-CARTILAGINOUS SYSTEM. 213 



ticity, extensibility, and contractility; how do these pro- 

 perties principally differ? 



e/2. Elasticity is a rapid, the others are slow actions. 



Q. What are the vital properties of this tissue? 



#. Organic sensibility and insensible organic contrac- 

 tility ; and these in a degree sufficing only for the nutri- 

 tion of the tissue. Neither active nor passive sympathies 

 are met with here. 



Q. Have the fibro-cartilages much disposition to ossify ? 



#. Not near so great as the cartilages. Beclard accu- 

 rately observes that there are temporary and permanent 

 fibro-cartilages. The first having served their purposes, 

 ossify; the second remain fibro-cartilaginous.
