Abstract
IN NATURE, vol. lvi. p. 259, Mr. Griffiths points out that recent comparisons of the values of the mechanical equivalent of heat, obtained by mechanical and electrical methods, suggest that the adopted value of the equivalent of silver may be in error to the extent of 1/1000. This adopted value rests, I believe, almost entirely upon experiments made by Kohlrausch, and by myself with Mrs. Sidgwick in 1882; and the question has been frequently put to me as to the limits within which it is trustworthy. Such questions are more easily asked than answered, and experience shows that estimates of possible error given by experimenters themselves are usually framed in far too sanguine a spirit.
