bread and water (chromic and osmic preparation). 

 Fig. 2. Section of the villus of a rat, killed fonr hours after a lueal cousisting 



of meat and fat (osmic acid preparation). 

 Fig. 3. Amoeboid cells from the lymphoid tissue of the villus of a dog, killed 



during absorption of mük. 

 Fig. 4. Section of part of the mucous membrane of the intestine of a frog three 



days after feeding with lard (osmic acid preparation). 

 Fig. 5. A Single columnar epithelium cell, isolated, more magnified. From the 

 intestine of a frog killed 2 days after having been fed with lard. The 

 lower end of the cell is broken off. The peculiar vacuolated coudition of 

 the fat globules mentioned in the text (p. 13) is well shown (osniic acid 

 preparation).
