Analysis of the crayons indicated the presence of lithopone, a white paint pigment. The chemist pointed, out that lithopone is essen tially a mixture of barium sulfate and zinc sulfide and reasoned that the zinc sulfide would, if taken internally, react with the acid gastric juices to generate hydrogen sulfide. It may have been absorption of hydrogen sulfide into the blood stream that caused the serious condition which nearly brought death to the baby." I have been in communication with Dr. Harry J. Usher, who is in charge of the Department of Analytical Chemistry at the Connecticut Agri cultural Experiment Station and have his confirmation that the above is the correct expression of his opinion. Robert A. lienee, JTJ>0 -2- April 29, 19k9 Well and good.
