Embryonic connective tissue (mesenchymatous tissue). (Bohm and Davidoff.) a, nucleus 

 of stellate cell ; 6, cytoplasmic process. The intercellular substance is of gelatinous con- 

 sistency and optically homogeneous. 



arranged in fine bundles, but the elastic fibres appear to be isolated, 

 and, though they may branch, do not appear to form a network.

Reticular tissue. Section through a lymph-sinus in a lymph-node of the rabbit. (Ribbert.) 

 o, nuclei of stellate cells of the reticulum ; 6, endothelial cells which are closely applied 

 to the reticulum. The lymphoid cells, or leucocytes, have been removed from the 

 meshes of the reticulum. 



Mucous tissue of a rather highly cellular character is abundant 

 in the embryo, where it constitutes an early stage in the development 

 of the fibrous tissues (Fig. 61). A variety less rich in cells forms
