It is written by many nutritionists and physiologists that Eskimos get the necessary calcium by chewing bones. Their celetons, as studied in our museums, indicate a plentiful alcium supply, and when I first heard that their calcium 'as derived from bone chewing it struck me as reasonable, 'here had certainly been in me no sign of calcium deficiency fter ten Arctic years, about half of which were exclusively n meat and the other half on a preponderance of meat. I could remember, thinking back, that I had chewed a Teat many bones. Now I worry somewhat, fearing I may ave given written adherence to the calcium-from-chewed-bones theory, but take some comfort in the fact that I have lot yet been able to discover this in my printed writings. For I realize now a flaw in the argument, serious if not fatal to it. On the basis of the preceding discussion of the differences n flavor and anatomical structure between seal and caribou bones, it can be stated simply and flatly that the man who chews a lot of bones in a caribou-hunting year will chew no bones at all in a sealing year.
