Extract from a review in ^'Nature," November 11, 1915. 

 " Too little importance has been hitherto attached by writers of scientific books to 

 the way in which they have been illustrated. The volume before us is a brave and 

 not unsuccessful attempt to guide the scientific writer, and to put into his hands a 

 manual which in clear and simi)le language reviews the various means by which book 

 illustrations are made. The author gives admirable advice on the preparation of 

 illustrations and on methods of drawing for reproduction." [S. P. T.]
