Abstract
THE advisability of publishing a laboratory manual which consists practically only of a reprint of the instructions given to the students in a particular college or university is a matter that is open to question. It may be objected that the instructions can only be of real value to those who have an equipment exactly the same as that in the laboratory of the authors, a coincidence that is likely to be rare, and that each teacher will preferably use instructions of his own, drawn up to suit the circumstances of his case. On the other hand, it may fairly be contended that such publications are of special value to teachers in that they enable them to compare their own methods with other people's, and to modify and improve their own courses as a result. From this point of view this volume, in common with others of the same kind, must be regarded as rather of value to the teacher than to the student. Indeed, as the instructions without the experiments are like the white of an egg without salt, the student can gain little from the present volume unless it is adopted by his teacher.
