Connective Tissue. — Tbe elementary parts which are found 

 in connective tissue may be divided into the essential, never- 

 failing components, and those which are met with only in cer- 

 tain localities. To the former belongs the fasciculated as well 

 as the more homogeneous connective tissue; to the latter, 



elastic fibres in their different forms 

 and conditions of development, 

 fat cells, cartilage cells, and 

 pigment cells of different kinds. 

 Besides these, connective tissue 

 contains also no inconsiderable 

 quantity of a gelatinous interme- 

 diate substance. The bundles of 

 the connective tissue are, among 

 the essential elements, those which 

 occur most frequently; each of 

 them consists of a certain number 

 of very fine fibrils, the connective 

 fibrils, which are distinguished 

 from their nearest allies, the finest 

 elastic fibres and muscular fibrils, 

 by their smaller diameter (O0003'" 

 — O0005'"), their pale colour, their 

 homogeneous appearance, and the 

 complete absence of striation. 

 They are united by means of a 

 small quantity of a clear connect- 

 ing substance, and thus form the 

 bundles in question, which in 

 many respects resemble those of
