MACMILLAN'S 

 SCIENCE MONOGRAPHS 



8vo. 



TT is intended that the Volumes in this Series shall 

 represent the expression of modern scientific work 

 and thought in definite directions. Each Volume will be 

 unique, inasmuch as the author will describe chiefly his 

 own contributions to the specific subject of scientific 

 research with which it deals. Results and conclusions 

 reached after years of investigation will be embodied in 

 the monographs, as well as original work not previously 

 published. The Series will thus present in convenient 

 form the views of high scientific authorities upon subjects 

 of outstanding importance ; and it will make eventually 

 a standing cyclopaedia of progress in natural knowledge. 



VOLUMES READY 



CRYSTALLINE STRUCTURE AND 

 CHEMICAL CONSTITUTION. By A. E. H. TUTTON, 

 D.Sc., M.A., F.R.S., A.R.C.Sc.(Lond.). 6*. 6d. net. 



NATURE. " It is a goodly story that Dr. Tutton has to tell, and well is it 

 told : without wearying the reader with an unwieldy mass of details, he presents in 

 all essential completeness a vivid picture of an unusually coherent series of investiga- 

 tions. . . . The book is one that should be read and studied by all interested in 

 crystals, their properties, and their formation." 



STABILITY IN AVIATION. By G. H. BRYAN, 



Sc.D., F.R.S., Professor of Mathematics in the University College 

 of North Wales. 6.y. 6d. net. 



WESTMINSTER GAZETTE. " We welcome Professor Bryan's book, 

 because it will go far to awaken the interests of scientific men in what has hitherto 

 been regarded as a fruitless pursuit ; and, so far as it treats of known types of flying 

 machines and their variants, it will doubtless lead to aeroplane stability being made 

 the subject of much more continuous study and investigation than has been possible 

 in the past."
