" The great advances in chemistry made with- 

 in recent years have rendered it alnioit impera- 

 tive that a new edition of Watts's Dictionary 

 should be prepared. Not only has an immense 

 number of descriptive facts been added to chem- 

 istry in the quarter of a century which has 

 elapsed since the publication of the first edition 

 began, but the whole aspect of the science, and 

 its relations to other branches of natural knowl- 

 edge, have greatly changed in that time. The 

 changes have been so great and far-ieaching 

 that a new edition of a. Chemical Dictionary 

 which saw the light twenty-five years ago must 

 needs be a new book."
