Note 2 — Chapter VIII
Reading edition
It is proper to mention here that the pendulum and magnetic observations, as well indeed as all others in physical science, were, upon my return, sent to the Smithsonian Institution at Washington, and were placed in the very competent hands of Mr. Charles A. Schott, Assistant in the United States Coast Survey, to whom I am indebted for most able and efficient coöperation, in the elaboration and discussion of my materials, preparatory to their publication in the "Smithsonian Contributions," to which source I beg to refer the reader for details.
