288 Canadian Record of Science. 



crystals and the general principles of crystallography are first 

 taken up, and then follows a detailed discussion of the crystallo- 

 graphic systems based mainly upon the symmetry of crystal forms. 

 A chapter is devoted to crystal aggregates, another to imperfections 

 of crystals, and an appendix to the discussion of zones, projection, 

 and the construction of crystal figures. Ths symbols of Weiss are 

 taken as a starting point, those of Naumann, however, being 

 generally employed, and the index symbols of Miller written beside 

 them. A somewhat fuller explanation and illustration of Miller's 

 index system than that found on pages 30 and 31, would probably 

 add to the usefulness of the volume. 



The book is well printed and well illustrated, and evidently the 

 proofs have been read with great care.
