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 con- 

 tributions 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 cyclo- 

 paedia of progress in natural knowledge.

 A.R.C.Sc.(Lond.). Ss. net. 



jV^rCW^.— "It is a goodly story that Dr. Tutlon 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. 5s. net. 



WESTMINSTER GAZETTE.— "^Ve 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 beinjj made 

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

 in the past."
