CONNECTIVE TISSUE.

the protoplasmic bodies, which this observer has discovered in the myxoma- 

 tous and fibrous connective tissue, as well as in that of the cartilage and 

 bone, has been successfully demonstrated by me in the cornea also. The 

 living matter presents in connective tissue two different net-works : a narrow 

 one, the meshes of which are filled with fluid, protoplasm, and another 

 with broader meshes, traversing the basis-substance. 



Development of Fibrous Connective Tissue. This article is a 

 translation of a publication which I made in 1873.* I have 

 lothing to add to the conclusions drawn at that time, but shall 

 make the explanation of the observations a little more detailed. 



'IG. 70. PERIOSTEUM OF THE FEMUR OF A NEW-BORN PUP. LONGITU- 

 DINAL SECTION. CHROMIC ACID SPECIMEN, SLIGHTLY STAINED WITH 

 CHLORIDE OF GOLD. [PUBLISHED IN 1873.] 



M, layer of medullary corpuscles; I, layer of corpuscles in the stage of indifference, pre- 

 ling the formation of basis-substance ; C and (7i, spindles of basis-substance of fibrous 

 icctive tissue ; E, elastic ledge. Magnified 800 diameters. 



In transverse sections of a shaft-bone of a newly born pup, we 

 cognize between the striated periosteum and the bone-tissue a 

 xroad layer of medullary tissue, into which project a few striated 

 mndles of the periosteum proper. t (See Fig. 69.)

t Th. Billroth ("Archiv f. Klin. Chirurgie," Bd. vi.) termed this layer 

 " cambium." A. Rollett ("Manual of Histology," by S. Strieker) illustrates 

 it in a transverse section of the fore-arm bone of a human embryo, five 

 months old.
