You have been told of the connexionsbetween the spinal nerves and those of organic life,through the medium of the sympathetic nerve (304).Now the fibres of the latter which communicate withthe spinal nerves are often interested in diseases of thesoft parts about the orifices through which these nervesleave the spinal or vertebral canal. Hence, disordersof internal organs often connected with affections of theperiosteum and the fibrous tissues around it; and themost profound knowledge, coupled with sufficient expe-rience, is required totrace the hidden chainof relation betweencomplaints seeminglyso dissimilar. 468.

The bony portions of the ribs do not reach thesternum, but you observe in Fig. 49, a white portionextending from the extremity of each rib towards thelatter bone. These are called the cartilages of the ribs,but they are really composed of bone in that conditionin which it is found in some parts of the skeletons ofchildren, and in the whole osseous system of certainfishes (159).
