(d) White Fibre-Cartilage. 



Small pieces of the intervertebral discs of a calf were hardened 

 in a saturated aqueous solution of picric acid, washed in alcohol, 

 stained in picro-carmine, embedded in paraffin, and sectioned. 



Study under high power. The intercellular matrix is 

 composed largely of white fibrous tissue stained yellow in 

 the picric acid. Between these bundles are found cartilage 

 cells, enclosed in a capsule, and often surrounded by a 

 narrow zone of hyaline matrix. Sketch as seen under high 

 power.
