Acknowledgment.
The author esteems it a privilege as well as a pleasure to give
expression to his sincere sense of gratitude to Prof. Remsen,under
whose guidance this work was carried on not only for instruction
received in the lecture room, but for his frequent suggestion, and his
constant and friendly interest in the work as it progressed. These have
at all times been an encouragement and an incentive.
He wishes also to express his appreciation of the instruction and
kindly guidance in the laboratory, of Drs. Morse and Renouf, as well as
of Dr. Ames of the Physical Laboratory.
