"The information conveyed in _The Art of Enamelling on Metal_ is as complete as can be expected in a manual of ordinary length, and is quite ample in all respects to start students in a most interesting branch of decorative art. All necessary requisites are fully described and illustrated, and the work is one, indeed, which any one may pursue with interest, for those who are interested artistically in enamels are a numerous body."--_Hardware Metals and Machinery._ * * * * * =Books on Textile and Dyeing Subjects.= * * * * * =THE TECHNICAL TESTING OF YARNS AND TEXTILE FABRICS.= With Reference to Official Specifications.

We have great confidence in recommending the purchase of this book by all manufacturers of textile goods of whatever kind, and are convinced that the concise and direct way in which it is written, which has been admirably conserved by the translator, renders it peculiarly adapted for the use of English readers."--_Textile Recorder._ "A careful study of this book enables one to say with certainty that it is a standard work on the subject. Its importance is enhanced greatly by the probability that we have here, for the first time in our own language, in one volume, a full, accurate, and detailed account, by a practical expert, of the best technical methods for the testing of textile materials, whether in the raw state or in the more or less finished product."--_Glasgow Herald._
