X. Is argon contained in vegetable or animal substances?

Abstract

At Professor Ramsay’s suggestion, experiments were undertaken to see whether argon could be obtained from nitrogenous vegetables or from animal tissues. Method :—A few grams of the substance, after drying if necessary, were ground to a fine powder, desiccated at 110° C., until the weight was constant, and a nitrogen estimation performed by Dumas’ method. It was supposed that any argon compound would be decomposed, when the argon would come off along with the nitrogen.
