For example, Remington has criticized the view that air-borne iodine plays any considerable role (266). The cycle, as far as man and (to a lesser extent) the domestic animals are concerned, is frequently modified by man himself through utilization of food material from wide sources, and recently, through deliberate selection of iodized material. Modifying Lunde’s scheme including man, it can be written :—- —> (Atmosphere)- > —> Land Plants ---> —> Land Animals- > \ Milk-> —> (Marine Plants —-> —^ (Marine Animals) —> —> Spring or River Water-> —> (Crude or Iodized Salt)-> y > Man’s Diet —> Man Y Man’s Excreta Soil —> (Selected food material, or sources of negligible importance are shown in parentheses.) Iodine is present in measurable amounts in all human and other mammalian tissues. Endocrine glands (with the exception of the testes and pancreas) contain relatively more than lion-endocrine tissue. Of the total amount in the organism one-half to two-thirds is in muscular tissue, one-fifth to one-tenth in the thyroid (300). The average iodine content for certain tissues of six adult women was, in gamma per cent. : heart, 53 ; liver, 57 ; spleen, 61 ;
