It includes only that which every well-informed person ought to know on the subject, and excludes whatever is of value only to those who are to be chemists, or who intend to apply chemistry to specific branches of business, as medicine, metallurgy, etc. For the extended and specific knowledge required for such purposes other books can be studied afterward, this book being suitable for a preliminary preparation. I will give a single example of the sort of selection I have practiced in carrying out my plan. I exclude the consideration of the tests of the presence of arsenic in cases of poisoning, because the application of them is so complicated that none but a professed chemist can make the investigation. On the other hand, I notice very particularly the chemical action of the whites of eggs upon corrosive sublimate, because, as poisoning with this substance is quite frequent, and promptness in the use of the antidote is all-important, every one ought to know what the antidote is, and he will certainly be the more prompt to apply it if he understand its modus operandi.2d. I recognize fully the distinction between a book for reference and a book for study. The pupil should have his book specially adapted for study- and the teacher should have, in addition to this, books for reference, so that his knowledge may be wider than that included in the textbook, in order that he may meet any inquiries that may arise, or add to the facts and illustrations which the text-book furnishes, as occasion may offer. Most text-books are too extensive, because the distinction referred to is not observed.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
