It was a very great desideratum to have a method for detecting
arsenic and separating it from the contents of the stomach and food
directly without previous destruction of the organic matter, and he
hoped Dr. Kohn would pursue his work in that direction.
Dr. Hurter said he was about to construct a new laboratory, and he
would assure them that one of its arrangements would be the
installation of electricity, by which to carry out researches similar
to those described. He was very glad to learn that the presence of
arsenic, etc., could be readily proved by means of electrolysis.
