The subjoined case owes its chief interest to the question of diagnosis involved in its consideration. The outline of the case is as follows:—

William G., set. 57, single, labourer, admitted into the Cambs. Asylum, Aug. 10, 1868. He was said to have had a previous attack of insanity at the age of 22, but to have kept well till within a few days of his admission, when he became noisy and excited. It was also stated that he had had four epileptic fits, but at long intervals.
