The author presents here a scientific study of peyote intoxication. He credits the introduction of this interesting intoxicant to the German pharmacologist L. Lewin, who in 1888 brought this Mexican drug, which is also known in commerce as "mescal buttons," to Europe, where it was identified as a species of Anhalonium, and in recognition of merit named Anhalonium lewinii. There seems little disposition in this country to grant this title. Coulter in 1894 proposed the name "Lophophora williamsii," and considers Anhalonium lewinii merely a variety rather than a distinct species. Even though the credit of discovery of this cactus may not belong to the German pharmacologist, it is interesting that attention had not been paid by American scientists to this intoxicant used by the Mexican Indians until a European called attention to it.
The first mention of peyote is to be found in the writings of the priest Bernardino Sahagun,
