Abstract
IN NATURE, vol. xix. p. 98, my name appears in a way that might lead the reader to infer that I was the inventor of the “cosine galvanometer.” My knowledge of this useful instrument was derived from Prof. Trowbridge, of Cambridge, U.S., who described it in 1871 in the American Journal of Science, vol. cii. p. 118. In my “Physical Manipulation” I omitted to mention, Prof. Trowbridge's name, supposing that his connection with the instrument was too well known to render it necessary.
