This is no longer the case in the treated animal which may rapidly loose some of its fat content. It is quite possible that fats or their precursors reach the muscles from the liver. Most of the time the i'*C content of the fats in the liver of treated mice is lower than the ^*C content of the fats of controls. This may also explain the low ^*C values in the muscle fats of the dinitro- cyclo-pentylphenol treated mice. Further information on this point could be obtained by studying the intrusion into the muscles of labelled fatty acids, labelled aceto-acetonate or other labelled precursors intro- duced into the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hevesy, Georg von, 1885-1966.
