Abstract
It was reported 1 earlier that white flaming carbon arc and quartz mercury vapor energy had little or no effect on a milk anemia in rats. Most of the observations were made with the carbon arc and continuation of the work has demonstrated a definite effect by the mercury arc, as evidenced by number and size of reds and hemoglobin content and saturation. Doses of about 10 minutes daily at a distance of 35 cm. seem optimal, larger doses showing a tendency to depress growth and produce burns. Doses of less than 5 minutes were practically without effect. Again no definite results have been obtained following exposure to the energy emitted by “Sunshine” carbons.
