[Chap. III. 



tissue differs from epithelial tissue in having a great deal of 

 intercellular substance between its cells, and according to the 

 manner in which this intercellular substance develops do we 

 get the different varieties of connective tissue. 



Connective tissue proper. — There are three principal varieties 

 of connective tissue proper : viz. the areolar, the fibrous, and 

 the elastic. 



Areolar tissue. — If we make a cut through the skin of some 

 part of the body where there is no subcutaneous fat, as in the 

 upper eyelid, and proceed to raise it from the parts lying beneath, 



Fig. 10. — Subcutaneous Areolar Tissue from a Young Rabbit. (Highly 

 magnitied.) (E. A. S.) The white fibres are iu wavy bundles, the elastic fibres form 

 an open network, p, p, vacuolated cells; g, granular cell; c, c, branching lamellar 

 cells; c', a flattened cell, of which only the nucleus and some scattered granules are 

 visible ; /, fibrillated cell. 



we observe that it is loosely connected to them by a soft filmy 

 substance of considerable tenacity and elasticity. This is areolar 

 tissue. It is also found, in like manner, under the serous and 

 mucous membranes,^ and serves to attach them to the parts 

 which they line or cover. Proceeding further, we find this 

 areolar tissue lying between the muscles, the blood-vessels, and 

 other deep-seated parts ; also forming investing sheaths for the
