    the saliva while the animal was alive, and made the first proving thereof on himself, using the triturations. A small Prover's Society having been formed, he proposed the proving of the globules obtained from Lappe (the highly esteemed apothecary in ^N'eudietendorf) under the name of Bruce a anti- dysenteric a. It was considered very doubtful by all the provers whether such high-potencies could produce any symptoms, and the correctness of the name Brucea for what was formerly called Angustura falsa was much doubted. Dr. Hering had proved for the first and only time in his life, globules of Theridion, which he had prepared by potentizing from the tincture to the thirtieth centesi- mal, and the effects were such that he never would make another proving with them; but he still had some doubts, because during the preparation of the potencies, he might have inhaled all the thirty potencies, one after the other. He still hoped to get some symptoms from the Brucea, and to make an analysis by provings, in order to ascertain whether it contained Strychnine or whether it could be the bark of the ]^ux vomica tree. Getting no symp- toms himself, and those of the other pro vers not being sufficiently characteristic, the provings obtained were published by Stapf in the Archives^ XIV, E'o. 2, p. 177, with the view of inducing others to make investigations, but without such a result. The provings of Lachesis and Crotalus were completed in Allen- town, Penna. The provings of Calc. phos. acid, was made there; likewise, Calc. phos. basica was fully proved, and the proving of HiPPOMANES EQUORUM and Castor equorum commenced. Many additional provings were also made of Kalmia, E'icandra and Viburnum acerifolium. In the Correspondenz-Blatt—a little paper started to save the enormous postal charges—were published the arranged symptoms of Baryta muriatica, August 31st, 1836 ; a condensed collection of the provings of Lapis magneticus, overlooked by Jahr; Cistus canadensis or Helianthus caradupe, according to the provings of G. H. Bute, and Mephitis putorius, January 18th, 1837; Pothos or IcTODES icETiDA, and Calc phos. acida, February 3d, 1873; San- GUiNARiA canadensis, by G. H. Bute, and Daphne indica, January 22d, 1873, and Apocynum cannabinum frorri Gray's Journal. Many indigenous plants were also proved in Allentown, such as Phytolacca, Gelseminum, Gymnocladus, etc. Returning to Philadelphia in 1839, the chemical family of salt- formers, of which Iodine has since been fully proved, were selected
