Within the past few years McNealy and Willems,1 Pressman,2 Scott and Zweighaft,3 Perusse,4 Burget, Moore and Lloyd5 and Collens and Boas6 published data on the absorption of dextrose from the colon which are not entirely in agreement. The subject is of sufficient importance from the clinical point of view to warrant additional studies.
I reported7 the results of studies on the absorption of dextrose from the colon of the anesthetized dog. It was assumed at that time that anesthesia and the attending operation played little or no part in altering the physiologic process of absorption from the large intestine.
The opportunity arose, however, to study absorption from the colon in the unanesthetized dog through the preparation of a colon loop. One need not, at this time, comment on the advantages or disadvantages of the use of the chronic loop for investigation of intestinal
