Excerpt from A Text-Book of Inorganic Chemistry
The present edition represents a thorough revision of the work by the Dutch author and the American collaborator. It profits by the author's experience with the frequent editions in other languages but is independent in composition.
Very many of the descriptive portions have been rewritten, notably those on the sulphur oxides and acids, rare gases, nitrogen oxides and acids, sodium hydroxide and carbonate, radio-active elements and platinum, as well as the sections on thermo-chemistry, colloids and the iron-carbon system, while the subjects of stability and the reality of molecules and atoms furnish new material. The chapter on metal-ammonia compounds is reprinted as approved by Professor Werner for the third edition.
Notwithstanding the appearance of differential formulæ in the book, it is believed that a student who is unfamiliar with the calculus should have little difficulty in understanding the meaning and use of such formulæ, provided he is willing to take the author's word for the solutions of the equations.
Independent students may well be cautioned against regarding any text-book as infallible. Even in a book with a world market, such as this one enjoys, undergoing many revisions by the author and by collaborators in other nations, and being frequently reviewed critically by the journals, there will, probably, always be some textual errors and some passages whose lucidity could be improved. Readers can therefore render great service by reporting all unsatisfactory passages to the publishers.
Thanks are herewith expressed to my colleague. Professor H. Monmouth Smith, for constant aid in detecting errors.
