Abstract
SURGICAL techniques for the production of artificial Siamese twins (‘parabiotics’) are well established for small laboratory animals, and, in skilled hands, provide an elegant method for study of hormone circulation and other problems involving humoral transmission. There is some doubt as to whether capillary anastomosis or the lymphatic system is the primary mode of transfer from one twin to the other; but, in either case, it would seem that parabiotic animals are excellent material for nutritional research. In this connexion, it may be of interest to record that a pair of rats joined in this way since shortly after weaning were among a number of animals studied during a preliminary investigation of the influence of age and diet on intestinal micro-organisms.
