PLATE VII 



FIG. i. Section of the scalp of an infant (hematoxylin-eosin), x 35. Ewing. 



This figure shows a collection of sebaceous glands near its upper portion; below the hori- 

 zontal diameter is adipose tissue ; a few sections of hairs are rather imperfectly shown at the 

 left border. 



FIG. 2. Section of the skin of the sole of the foot (hematoxylin-eosin), x 20. Author's 

 collection. 



This figure shows, with great distinctness, the two layers of the epidermis, with spiral 

 sudoriferous ducts in the horny layer; the ducts take a nearly straight course through the 

 corium, which is stained pink ; the sudoriparous glands lie in the panniculus adiposus, just 

 beneath the corium. 



FIG. 3. Section of the cortical substances of the kidney of the dog, injected and stained 

 (hematoxylin-eosin), X 125. Author's collection. 



This figure shows three Malpighian bodies and part of fourth, each enclosed in its capsule. 

 It also shows the general arrangement of the convoluted tubes. The magnification is too low 

 to show distinctly the cells lining the tubes. 



FIG. 4. Section of the kidney of the cat, injected, X 125. Author's collection. 



This figure shows only the glomeruli and the distribution of capillaries in the cortical 

 substance. 



FIG. 5. Cross-section of the liver of the pig, injected and stained (hematoxylin-eosin), 

 X 125. Author's collection. 



This figure is from a liver injected with blue through the portal vein, with the cells stained. 

 The lobular vessels are purple ; the staining shows the cells arranged in radiating columns ; the 

 central (intralobular) veins are empty. A section of a small artery appears at the lower part of 

 the figure. 



FIG. 6. Cross-section of a lobule of a pig's liver (hematein and eosin), X 50. Ferguson. 



In this figure the empty intralobular vein is shown in the centre of the polygonal section 

 of the lobule, three sides of which are shown to the left and above ; the hepatic cells are shown 

 in slightly wavy columns radiating from the centre toward the periphery.
