Excerpt from Twenty Lessons in Inorganic Chemistry: Embracing the Course of Instruction in Chemistry Required for the First Stage or Elementary Classes of the Science and Art Department This little book has been prepared in order to ease the teacher's task of conveying, in Twenty Lessons, sound chemical instruction to their pupils, and to help the latter to get as quickly as possible over the difficulties which the study of chemistry presents. It is based upon the plan sketched out in the Science and Art Directory, which there is really little fault to find with, except, perhaps, on the ground that it expects too much from young pupils, such as are usually found attending the elementary stage of instruction. I have confined myself all but exclusively to the simple experiments traced out by Dr. Frankland. A glance at the table Of contents will show that I have gone a step further, and have added instruction in the few other non-metallic elements which are not included in the syllabus, but are, in my opinion, capable of completing the interesting relations of the natural groups which the non-metallic elements form, and thus of contributing materially to the enjoyment of the beauty and symmetry which pervades chemical science. I have made them serve, moreover, as a natural basis for conveying the all-important theoretical instruction in volume combination, and combination according to atomic proportions by weight. These additions are, however, printed in Appendices and in different type from the main portion of the text, and their study is left optional.
