Curves, constructed from the measurements recorded iu Table 1, expressing the variations in the breadth of the interglandular spaces of the glands of the dififereut regions of the dog's large intestine. A, when contracted, and B, when distended. the glands of the ascending colon are most thickly distributed. ^lathe- matically expressed, the interglandular space varies directly as the dis- tension. These observations indicate obviously that in all conditions the mucosa of the ascending colon is more thickly studded with glands than any other region of the large intestine. Further, the observation made above^ that distension decreases the depth of the glands, coupled with the observation that it results in an increase in the breadth of the inter- glandular spaces, indicates that distension must increase the absolute area of the superficial epithelium or of that glandular surface directly exposed to the intestinal contents. Variations in Thickness of Muscvlaris Mucosae. The thickness of the rauscularis mucosse was measured from the inner margin of the inner, circular layer, to the outer margin of the outer, lonsfitudinal laver. Contracted, the muscularis mucosfe is thickest in. Please note that these image
