Excerpt from Chemical Lecture Experiments: Non-Metallic Elements The object of this book is twofold. Firstly, it is intended to supply chemical lecturers and teachers with a useful repertoire of experiments, suitable for illustrating upon the lecture table the modes of preparation, and the properties, of the non-metallic elements and their commoner and more important compounds. I have therefore given such full directions for the preparation and performance of the various experiments described, as will enable any experimenter to successfully repeat them. No mere description of experiments, however minute, can entirely take the place of experience, but it has been my endeavour throughout this book to give such details, resulting from my own experience, as shall meet as far as possible the lack of experience in others. No account of any experiment has been introduced into the book upon the authority solely of any verbal or printed description, but every experiment has been the subject of my personal investigation, and illustrated in every case, with the exception of three, by woodcuts made from original drawings. What should be and what should not be included under the head of 'experiments suitable for illustration upon the lecture table' may be a matter for difference of opinion, and must depend often upon circumstances.

Written by the author of the award-winning "Chemische Kabinettstücke" this book demonstrates over 80 enjoyable, impressive and sometimes almost unbelievable chemical experiments for the classroom, lecture hall or home. All the experiments are explained in full, and have been tested several times such that their successful reproduction is guaranteed. Grouped into several cycles -- water, the color blue, the color red, soles, and self-organization -- the topics are perfect for experimental lectures or school projects. Detailed illustrations and the lively writing style make this book equally attractive to readers interested in chemistry, even if they are unable to perform the experiments.

Excerpt from Chemical Lecture Experiments The demonstration of chemical phenomena on the lecture table, though originally strongly imbued with an element of mysticism inherited from the hermetic art, has always been considered an essential phase of chemical instruction. After chemistry was placed on a broader basis by Lavoisier, and the black art converted to a science, experimental lectures still remained a legitimate factor in presenting the subject. Soon text-books and class recitations and later laboratory exercises for the student supplemented the lecture, and with the introduction of the latter a tendency to neglect the experimental lecture developed. Laboratory exercises, however great their influence in developing the experimental side of teaching the science, have their limitations, experimentally and educationally, and cannot supplant the experimental lecture, for it is in the lecture, and there only, where each experiment stands out clearly defined and unattended by the distractions necessarily accompanying laboratory exercises, that the first accurate observations of chemical phenomena can be made by students. The late Professor Josiah P. Cooke, though one of the first to introduce laboratory exercises into the educational institutions of this country, said, nevertheless, "Experimental lectures are, I am convinced, much the best way of presenting these subjects [Chemistry and Physics] as systematic portions of knowledge."
