_Divining Rod_ (Vol. viii., p. 293.).--In the first edition of his
_Mathematical Recreations_, Hutton laughed at the divining rod. In the
interval between that and the second edition, a lady made him change his
note, by using one before him at Woolwich. Hutton had the courage to
publish the account of the experiment in the second edition (vol. iv. pp.
216-231.), after the account he had previously given. By a letter from
Hutton to Bruce, printed in the memoir of the former which the latter
wrote, it appears that the lady was Lady Milbanke.
