REPAIR OF WHITE FIBROUS TISSUE. 113 



and formation of fibrous tissue T have ventured to 

 bring forward. See my Lectures delivered at the 

 Royal College of Physicians, 1861. 



164. Repair of white fibrous tissue. This simple 

 tissue is repaired after injury by the development of 

 tissue of the same character. White fibrous tissue 

 may be formed by white blood- corpuscles, or by the 

 masses of bioplasm descended from them. In the 

 repair of injuries to arteries and veins, Mr. Lee and 

 myself traced the production of white fibrous tissue 

 in what was clearly at first but fibrin deposited from 

 the blood, and I have shown that the recent lymph in 

 certain inflammations has a similar origin, and is 

 formed in the same way. In the repair of a divided 

 tendon, masses of bioplasm probably result partly 

 from the multiplication of the adjacent bioplasm of 

 the tissue itself, and partly from the white blood- 

 corpuscles which have escaped from the divided ves- 

 sels, or from masses of bioplasm descended from 

 these. 



165. Bioplasm of the cornea. Stellate masses of 

 bioplasm are remarkably distinct in the corneal tis- 

 sue of all animals, where they exist in great number, 

 and possess long branching processes which anas- 

 tomose freely with one another, and which may be 

 distended with fluid, or contain very little, as was 

 explained in the case of the branching pigment cells 

 of the frog, 131. These are the so-called corneal 

 corpuscles, and are to be demonstrated in any corneal 

 tissue without difficulty. Amongst them are, how - 

 ever, masses of bioplasm which belong to the nerves, 

 and some few which are not connected with any tis- 

 sue (wandering cells of Recklinghausen). In spe- 

 cimens I have prepared the numerous stellate masses 

 of bioplasm are seen very distinctly, and the anasto- 

 moses between the radiating processes can be detected 

 without difficulty. These bear to the firm but trans- 

 parent corneal tissue just the same relation as the
