The German surgeons, chemists and pathologists who have investigated this condition have not been able to decide which of the many organic compounds produced or used in the dye industry is to be considered as responsible for the development of the cancer, some incriminating the anilin itself, others finding evidence that tends to incriminate certain groups of dyes. More recently, Alice Hamilton2 has discussed the subject at length, and suggests the possibility that arsenic, present as impurities in the chemicals used in the dye works, may be the exciting agent.
