The intestinal lymphatics play only a small part in the absorption of vitamin B 12 from the gut in the rat. The activity which appears in the intestinal lymph after a small dose of the labelled vitamin (5 µmg.) is probably due mainly to recirculation and transfer from the plasma. When ten times this dose is given, there is a higher concentration of activity in lymph than in plasma, which suggests that there is then direct uptake by the lymph from the intestinal wall.
