Excerpt from Practical Chemistry for Engineering Students Much of the work in this book is quantitative, and the student is encouraged throughout, to check the quality of his work by weighing the materials used, and the products into which these materials may be converted. For these weighings the balance is made use of, and its importance in chemical work demands a few explanatory remarks concerning the principle on which it works and the manner Of using it. The mechanical principles underlying the construction of the balance cannot be discussed here in full, and the worker is referred to text-books on physics for a detailed description of a delicate balance.

Excerpt from Practical Chemistry for Engineering Students One of the practical difficulties encountered by the teacher in carrying out modern schemes of technical education arises from the failure on the part of the students preparing for some particular profession or industry to realise the importance of subjects which they regard as being outside their own province. This difficulty is experienced very generally; it constantly arises, for example, in connection with the professional training of such classes of students as those preparing for medicine or pharmacy, or for the various branches of engineering. It is to this last group of students that the present little work by Mr. Arthur J. Hale especially appeals. Those who are responsible for laying down the broad principles of training for the mechanical engineer have wisely included Chemistry as an essential subject. The leaders of the engineering profession both in this country and abroad are unanimous in urging the importance for engineers of a sound knowledge of at least the general rudiments of chemical science. Such knowledge can only be acquired during the early years of training, and it naturally falls to the duty of the chemical staff in our Technical Schools and Colleges to carry out this part of the students' curriculum.

Excerpt from Practical Chemistry A textbook intended for the first year of chemistry should meet certain requirements. Both pupil and teacher must be considered. The pupil needs a book which is written plainly, illustrated fully, and applied practically; which stimulates interest in chemistry. And which can be studied profitably. The teacher needs a book in which the text is carefully selected, judiciously apportioned, and properly arranged; which provides teaching material, and which can be taught successfully. The author believes his practical chemistry meets these requirements. The text includes the facts and principles suitable for beginners. N 0 important topic has been omitted. The selection is varied. Ner mitting the use of the book in different kinds of classes. The topics suggested by the College Entrance Examination Board and the Board of Regents (new York) have been incorporated. The style and arrangement are clear short sentences, brief para graphs, explanatory examples, lettered subdivisions numbered sec tions, instructive topical headings. Unusual care has been taken to write clearly such topics as symbols, formulas, equations, atomic weights, molecular weights, and valence.

Excerpt from Practical Chemistry: Part I. Elementary In all the experiments I have endeavoured to pay heed to the exigencies of teaching practical chemistry to classes of students, and to students who have not very much time to devote to the study. The book ought to be used in connection with Lectures and Demonstrations. The first section follows pretty closely the order in which I have attempted, for some years, to develop the subject-matter of elementary chemistry in my own lectures. All the experiments described in this Part have been tried repeatedly in the laboratory. By the kindness of the Publishers I have been allowed to use the proof-sheets in the laboratory before making the final corrections. I can, therefore, affirm that the experiments are workable.

Excerpt from The Student's Practical Chemistry: A Text-Book on Chemical Physics and Inorganic and Organic Chemistry The authors of the following pages have made it their object to produce a book of practical use to the student, by furnishing him with clear and simple 'explanations of the subject; and to those more pro ficient in scientific learning, by giving them in small compass, convenient memoranda of important facts, numbers, references, etc. The effort has also been made to embody all the valuable novelties in the branches discussed (many of Which have not yet been introduced in any text-book), and thus to bring this Work down to the present time.

Excerpt from Elementary Practical Chemistry: Inorganic and Organic Directions are given in the making up of reagents for students who are working without the aid of a teacher. Objection may be taken by some to the way in which it is recommended that results should be stated, but the authors find after several years practical experience in laboratory teach ing, that this method leads to clearness of expression, and the rapid examination of a student's work.
