ResumoTHE first serious effort to estimate the total quantity of oxytocin and vasopressin in the important hypothalamic divisions of the neurohypophysis in comparison with the posterior lobe was made some years ago by Hild and Zetler (1951-52). Although most of the subsequent observations of these authors were made in dog tissues, the distribution of the hormones in the hypothalamus and posterior lobe was also investigated in the hog and ox and in man. Similar studies, undertaken later in the dog by improved methods (van Dyke, Adamsons and Engel, 1955) have required modification of some of the conclusions reached by Hild and Zetler. These improved methods have been used for investigating the distribution of the hormones in the hypothalamus and posterior lobe of camels (Camelus dromedarius) from the Algerian Sahara which were used for water balance studies by two of the authors (Schmidt-Nielsen et al., 1955). The unique ability of this large mammal to withstand water-deprivation suggested that the estimation of hormone-distribution in its tissues could yield interesting results which are here summarized and compared with those obtained in other mammals.
