intercellular substance lying between the cells. Connective 

 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 modifications of 

 connective tissue proper ; viz. the areolar, the fibrous, and 

 the elastic. 



Areolar tissue. If we make a cut through the skin, and pro- 

 ceed to raise it from the parts lying beneath, we observe that it is 

 loosely connected to them by a soft filmy substance of consider- 

 able tenacity and elasticity. This is areolar tissue. It is also

 branes, 1 and serves to attacli 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 muscles, the
