Abstract
Summary
1. The silicon content of the tissues of man and rat were reinvestigated by a modified King's method, in which contact with glassware was avoided. 2. All tissues studied, except bone, contained between 2-10 μg silicon /g of dried tissue. Bone contained approximately 100 μg silicon/g of dried tissue. 3. In a single balance study, 90% of the silicon in rat food was excreted in the feces; some silicon was excreted in the urine.
