FIG. 270. L.S. Large Intestine. 



12. Vermiform Appendix (Rabbit). This is 

 instructive on account of the lymphatic follicles 

 it contains and the micro-organisms contained 

 in these follicles (p. 284). Fix it in mercuric 

 chloride and treat it as recommended for the 

 other parts of the intestine. The lymph-sinuses 

 are readily injected by the "puncture" method 

 with watery solution of Berlin-blue. Fix in 

 Muller's fluid and harden in alcohol. 



The lymph follicles are arranged in two or 

 three rows, the one inside the other, but the 

 innermost layer does not project beyond the level 

 of the mucous membrane. The apices of the 

 inner row are covered only by cylindrical epi- 

 thelium.
