Abstract
IN the course of an investigation into the mineral content of vertebrate tissues, mostly human, by the spectrographic method of analysis already described in NATURE,1 the choroids of an ox's eyes were found to contain a notable quantity of barium, the percentage in the tissue dried at 100° being estimated at nearly 1.5; a trace of strontium was also present. The choroids of a sheep's eyes analysed at the same time gave no indication of barium, though a trace of strontium was present.
