As the name implies, this book is a laboratory manual and syllabus. As such, it is beautifully illustrated with original drawings and tables which are well adapted for the class of students for which the manual was intended. The fact that it has now gone into the third edition indicates a degree of popularity which cannot be disregarded. It is elementary, to be sure, but evidently well suited to the class of students using it. It can be well recommended to any one interested.
