Excerpt from An Address Delivered Before the Massachusetts College of Pharmacy: At the Ninth Annual Commencement, on the Relations of Chemistry to Pharmacy and TherapeuticsThe researches of modern chemistry have, moreover, shown us many remarkable combinations in which metals and other elements of great therapeutic value are combined in a still more intimate manner with the organic elements than in the salts just mentioned. Such are the compounds of antimony, arsenic, mercury, and zinc, of bromine and of iodine, with the alcohol radicles or their deriva tives. In many of these the physiological action of these elements is completely masked, as in cacodylic acid, an arsenical derivative of methyl while the closely related alcarsine exhibits in an exalted degree the physiological effects of arsenical compounds, and has been employed as a therapeutical agent. Still more recently a mer curio compound of ethyl has been introduced into the materia med 1ca as an active form of mercury, possessing many advantages over the ordinary preparations of that metal.The related compounds of iodine present some remarkable illus trations of the principle just indicated. In iodoform, this element, to the extent of ninety-six per cent, occurs, so combined with carbon and hydrogen that its peculiar physical characteristics are wholly concealed in the form of a fragrant, aromatic, yellow, crystalline solid. It is now nearly thirty years since, having made this singular compound the object of study and experiment, I in vain suggested its medical use to alate distinguished professor in one of our schools of medicine. T 0-day, however, this substance has taken its place in themateria medica as a valuable preparation of iodine. The com pounds of iodine, with the alcohol radicles, have also been introduced into medical practice with the promise of precious results unobtain able by the saline preparations of this element. The iodides of methyl and butyl in solution, administered internally or by way of sub-cutaneous injection, not only exert a remarkable sedative power, but by their specific action upon the glandular system, which they share with other compounds of iodine, have been shown to possess a great value in cancerous affections. It is probable that these organic compounds may be decomposed in the organism, thus liberating in active forms the iodine which they contain.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
