' His most important contribution to theoretical chemistry.' D. N. B. 



' Mansfield wrote this book to defend the principle, that the facts of voltaic decomposition afforded the true indication, 

 if properly interpreted, of the nature of the saline structure and of the atomicity of the elements that built it up ; and 

 beheld that this structure or form of constitution is only one, but a most important one, among the types of constitution 

 on which chemical compounds can be moulded.' Editor's prefuv, which also contains an interesting biographical sketch. 



The author died a martyr to science at the early age of 35, 'from injuries received by carrying a blazing naphtha still 

 into the street, in an attempt to save the premises.
