As the time for combined revision of manuscript and proofs has been rather
limited, the Authors, in justice to each other, desire to explain that Mr C. Walker
is responsible for the sections dealing with Qualitative Analysis and the Prepara-
tion and Properties of Gases (pages 1 to 65), and Mr W. A. Macleod for the
sections dealing with Quantitative Analysis (pages 65 to 315), Assaying,
