Proximate composi- tion and the trace element content of the rations are given in Tables 2 and 3, and levels of radioisotopes in the rations are presented in Tables 4 and 5. centage or unit weight basis for total diet Results are given both on a per(Tables 2 (Tables 3 and 5). and 4) and as amount The former to permit compari- son of the relative composition of individual rations and to facilitate evaluation of the contributions made items in each diet; by specific and the latter to show the actual amounts consumed in a 24-hour period. In evaluating the chemical constituents consumed by an individual in a 24-hour period, diet is of much importance. the gross weight of the total Comparing the proximate chemical composition on a percentage basis with the published chemical composition of some of the items which constituted the samples, it is possible to account for the variation in moisture, protein, fat, carbohydrate and ash content of the different diets. Since the information on the nutritional aspects of the Rongelapese diet is limited, comparison of the data with that
