Spectrographic Analysis of Biological Materials
A study of elemental variation in the tissues of the individual was made by emission spectroscopy. Tissue ash was burned in air; various elements appeared in the arc at different times, the most volatile early and the more refractory later. Precision was found to be adequate for a survey of values and observation of gross difference. Method and results are summarized.
