different animals, and in the connective tissues of different parts. In the vitreous 

 humour of the eye no fibres are developed, and the cells become for the most part 

 either atrophied or much modified, and remain relatively few in number. The 

 so-called jelly-like connective tissue which is thus produced consists therefore almost 

 entirely of ground-substance. 



Connective tissue appears to be readily regenerated, although the new cicatricial 

 tissue which is formed in place of that which has been removed by the knife or by 

 disease, is not always obviously of the same character, either as regards its cells or 

 fibres, as the tissue it replaces. 



As to the mode of its regeneration there is still some uncertainty. It was 

 believed by Cohnheim, whose views have been supported by the experiments of 

 Ziegler, that the new tissue was formed by the leucocytes (lymph-corpuscles) of 

 the granulation tissue which first appears in the wound. But it is affirmed 

 on the other hand by other observers that the leucocytes, although unquestionably 

 the precursors of the newly-forming tissue, do not take any direct part in its 

 formation, but are gradually replaced by plasma-cells of the surrounding tissue 

 which also wander into the space within which the new tissue is to become formed. 

 Here they produce the cicatricial tissue, either by immediate transformation of 

 their protoplasm into fibrils, or by an extracellular formation in the adjacent 

 ground-subs tance .
