important peculiarity in the structure of this tissue is that it is abun- 

 dantly supplied with bloodvessels and nerves (see Plate X, Fig. 4). 



Fibro-cartilage, found in the synchondroses, the interarticular disks 

 and the intervertebral cartilages, is composed of interlacing bundles of 

 fibrous tissue surrounding individual cartilage-cells or small groups of 

 cells. This structure more nearly resembles tendon than it does true 

 cartilage. 



The reader is referred to works on anatomy for a history of the 

 action of the muscles. In some works on physiology will be found 

 descriptions of the acts of walking, running, leaping, swimming etc. ; 

 but it has been thought better to omit these subjects, rather than to 

 enter so minutely as would be necessary into purely anatomical details 

 and to give descriptions of movements that are simple and familiar.
