Mellor, J. W. Crystallization of iron and steel: an introduction to the study of metallography. [*]$1.60. Longmans.

“It is certainly a convenience to possess such a book.... In six short and lucid chapters—originally lectures delivered in 1904 to the engineering students of the Staffordshire county technical classes of the Newcastle high school—we are taken from a well-put statement of what is known respecting the solidification and cooling of alloys in general to the consideration of the phenomena recognized in iron and steel in particular, and, lastly, to practical directions for the due preparations of specimens for microscopic examination.”—Ath.

“It must be regarded as an ‘ad interim’ report only. Looking at Dr. Mellor’s little volume in this light, we have nothing but praise to award it.”

[*] “This second chapter is the only unsatisfactory one of the book. Confining himself to limited space, the writer has sacrificed conciseness to mere brevity. The two predominant features of the book as a whole are the great concentration of information into a small space, and the interesting manner in which it is presented, which latter never fails to attract. This clouding of the main issue by the introduction of data not absolutely necessary is one of the principal weaknesses of the book. When all has been said, this book is the best popular introduction to the study of metallography that we have.”

“The presentation is without bias, and each theory and method is described and examined as clearly and fairly as the author’s evident lack of practical acquaintance with the subject as a whole will permit.” A. McWilliam.
