these ribbons are composed of rows of globular elements ; others 

 are broken up into a number of fusiform corpuscles, and again 

 others are in part made up of these corpuscles, while another 

 part retains the character of a periosteal ribbon. The transition 

 of granular corpuscles into periosteal rhombs, which are infil- 

 trated with basis-substance, and look apparently homogeneous, 

 is nowhere abrupt. The images of either variety may, to such

 appear in part pale and granular, and in part homogeneous, like 

 basis-substance. In this specimen the single protoplasmic cor- 

 puscles, without exception, also exhibit the features described 

 above. (See Fig. 150.) 



At the point of the most intense inflammation, in the peri- 

 osteum under consideration, extensive fields are transformed into
