1. The normal oxygen tension in the mucous membrane of the stomach of the cat and rabbit is about 10 to 20 mm. Hg, while the carbon‐dioxide tension is about 40 to 60 mm. Hg. 2. The normal oxygen tension in the mucous membrane of the small intestine of the cat and rabbit is about 20 to 40 mm. Hg; that for the dog may be slightly higher. The carbon‐dioxide tension is 35 to 60 mm. Hg. 3. Anawsthetics, particularly urethane and amytal, may cause a rise of carbon‐dioxide tension and a fall of oxygen tension in the tissues, the average change being about 4 mm. Hg in each case. Individual animals may show much more marked effects than these.
