Excerpt from Chemistry IN preparing a second edition of the work on chemistry by the late Professor Brande and myself, I have endeavored to carry out the principles which in uenced us in the selection of subjects and in the mode of treating them: We felt that there was a large amount of useful chemical kwledge available for. The student, but that it was too often locked up in elaborate treatises, and incorporated with sub jects of practical interest. Our object in undertaking this work was to furnish the reader, whether a student of medicine or a man of the world, with a plain introduction to the science and practice of chemistry. With this view, we avoided as much as possible the introduction of questions connected with abstract science or with chemical philosophy, and we excluded from our pages the formulae and descriptions of substances which were never likely to be seen except as rare and curious specimens in the cabinets of professors. The chemistry of every-day life is quite sufficient to give full occu pation to a medical student. If, after the completion of his medical education, he has the time and inclination to devote to the study of atoms and the numerous and con icting hypotheses on their combina tions in groups and series, there can be objection to his taking up the examination of these recondite subjects, but let him make himself master of what is simple and practical before he occupies valuable time in studying that which is complex and hypothetical.
