 Structure of the Pancreas/' and " On Some Structures 

 found between the Renal Artery and Vein.'' 



Fig. 1. — X 52. Alveoli of the pancreas of the guinea-pig. a. Agglomera- 

 tions of cells with large and distinct blood supply. h. Normal pancreatic 

 tissue, c. Coagulated effusion into iuteralveolar spaces. 



Fig. 2. — x 680. Cells from agglomeration {a, fig. 1) isolated.

 the pancreas of the guinea-pig. a. Normal pancreatic tissue, h. Fibrous 

 connective tissue surrounding duct. c. Chain of mucous glauds. d. Columnar

Fig. 4. — X 56. Glandular body occurring between the renal artery and vein 

 in man. The drawing shows the general arrangement of fibrous trabeculse, cell 

 masses, and the channels between them, a. Fibrous capsule continuous with 

 trabecule throughout the gland, h. Masses of cells resembling lymph-cor- 

 puscles, c. Spaces between cell masses and trabeculse in which blood is 

 circulating. 



Fig. 5. — x 520. Portion of the preceding more highly magnified, a. 

 Fibrous trabeculse. b. Cell masses, c. Space between these which con- 

 tains blood, d. Blood capillary opening into the space between cell masses 

 and trabecular.
