happens to be so sectioned. One may indeed be obliged to examine 

 a dozen slides before succeeding.) Note 



a. The capsule (of Bowman or of Miiller) . (Observe its thick- 

 ness, as this becomes important in connection with the pathology 

 of the kidney.) 



b. The flattened cells lining the capsule. (Many of them will 

 have become detached in the preparation of the section.)

A. Ascending limb of Henle's loop. 



B. Collecting tubule longitudinal section. 



C. Collecting tubnle. The upper part of the tube is not sectioned, but shows the attached 

 bases of the lining cells, and thus simulates pavement epithelium. A, B, and C are in a pyramid 

 of Ferrein. 



D. Capsule of a Malpighian body. The emerging tubule is not shown, as the body is in T. S. 



E. Flattened lining cells of D. 



F. Glomerulus. 



G. Efferent arterioles. 

 H. Afferent arteriole. 

 I. Convoluted tubules. 



J. Ascending limb of Henle's loop. 

 K. Intertubular capillaries. 



c. The glomerulus. (The great number of nuclei obscures the 

 loops of capillaries. Remember that the nuclei belong partly to the
