7. A Bibliography of Clays and the Ceramic Arts / by John 

 Casper Brannee. Pp. 451, 8vo. 1906. Published by the 

 American Ceramic Society. — Some ten years since, the author of 

 the present volume published, as Bulletin No. 143 of the U. S. 

 Geological Survey, the first edition of the Bibliography which, 

 more than doubled in size, now appears in the present volume ; 

 this first edition contained 2961 titles while the one now issued 

 has 6027. To the work of thus expanding and completing the lit- 

 erature of this important subject, Professor Branner has devoted 

 much time during the past ten years. The manuscript was pre- 

 sented by the author to the American Ceramic Society, and the 

 volume is now issued by them and given to the public at a very 

 moderate cost. The attitude of the Society towards the author's 

 gift and the value of the work in general will be inferred from 

 the following sentences taken from the publisher's preface : " The 

 Society feels that the unselfish devotion and the utter absence of 

 self-interest betrayed in this course is as beautiful as it is unusual. 

 It is a fine example of the best traditions of scholarship and the 



true spirit of the scientist We believe that this work, 



placing in concrete form before the young students of the rising 

 generation the sources of the knowledge which they are seeking 

 to acquire, is destined to profoundly affect the scholarship and 

 progress of our time in this branch of human endeavor. . . ."

 Stuttgart, 1906. — Entirely aside from the many valuable contri- 

 butions to mineralogic and petrographic science which this vol- 

 ume contains, it is a striking example of the progress which has 

 been made in these fields of work and investigation since the 

 master whose achievements it is intended to honor and commemo- 

 rate began his labors. The science of petrology owes its present
