1. During the absorption of isotonic solutions containing 160 mM Na, 135 mM Cl and 25 mM HCO 3 , the contents of rat jejunum become progressively more acid than the contents of the ileum or colon. 2. During absorption there is a net entry of total CO 2 into the contents of the ileum and colon, while from the jejunum there is a net absorption of total CO 2. 3. The carbonic anhydrase inhibitor 6063 depresses the absorption of water and electrolytes from the jejunum, ileum and colon, and reverses the direction of net movement of CO 2 in ileal segments. 4. After absorption of saline solutions, the water content of the wall of the jejunum and colon is increased.
