The four Dutch monographs above cited are especially valuable. 

 They represent a revision of all atomic weight data down to 1853, as 

 divided between four writers. 



For the sake of completeness the peculiar volume by Hinrichs * must 

 also be cited, although the methods and criticisms embodied in it have 

 not been generally endorsed. Hinrichs' point of view is so radically 

 different from mine that I have been unable to make use of his discus- 

 sions. His objections to the researches of Stas seem to be quite un- 

 founded ; and the rejoinders by Spring and by Van der Plaats are suffi- 

 ciently thorough.
