86- EXPLANATION OF PLATES. 



FIG. 11. Silver preparation of the peritoneal surface of the centrum ten- 

 din eum of the diaphragm of rabbit, as in Fig. 7. 

 M. p. III. 5. 



t. Endothelium which covers the serosa over the tendon- 

 bundles. 



g. Stomata over the straight lymphatic vessels, some of them 

 open, some collapsed; the surrounding endothelium of a 

 germinating character. 



FIG. 12. Silver preparation from the same mesentery as Fig. 9. 



M. p. in. 5. 



a. Stomata, the surrounding endothelium c of which, as well as 

 of lymphatic sinuses Z>, is intensively germinating. 



1. The endothelium of lymphatic sinuses, the stomata of which 

 are widely open, so that the endothelium of their bottom 

 can be seen. 



d. Common flat endothelium of the general surface. 



FIG. 13. Silver preparation of the fenestrated portion of omentum of 

 guinea-pig suffering from chronic peritonitis. 

 M. p. III. 7. 



a. Thin trabeculee covered with common flat endothelium. 



6. Abundant germination of endothelium, springing ofl" from the 



surface of a larger trabecula c, and continuing on the 



smaller secondary trabecula?. 



PLATE IV. 



FIG. 3 4. Silver preparation of the pencilled pleural surface of the centrum 

 tendineum of a guinea-pig suffering from slight chronic inflammation 

 of the serous membranes. 

 M. p. III. 7. 



a. The endothelium of lymphatic-capillaries, 

 c. The lymph-canalicular system of the pleural- serosa ; the 

 branched cells, which occupy that 1. c. system, are in some 

 places distinctly to be seen. 

 At fc, these cells (respectively the lacunae of the 1. c. system) 



have become more numerous by division. 



At d, the continuation of the endothelium of the lymphatic ca- 

 pillaries with the cells of the 1. c. system is clearly to be seen.
