its gradations, with exquisite nicety, in one of the chapters of his Rasselas[1]. But there is surely a clear distinction between a disorder which affects only the imagination and spirits, while the judgement is sound, and a disorder by which the judgement itself is impaired. This distinction was made to me by the late Professor Gaubius of Leyden, physician to the Prince of Orange, in a conversation which I had with him several years ago, and he expanded it thus: 'If (said he) a man tells me that he is grievously disturbed, for that he imagines he sees a ruffian coming against him with a drawn sword, though at the same time he is conscious it is a delusion, I pronounce him to have a disordered imagination; but if a man tells me that he sees this, and inconsternation calls to me to look at it, I pronounce him to be mad.'

Some have fancied themselves to be deprived of the use of their limbs, some to labour under acute diseases, others to be in extreme poverty; when, in truth, there was not the least reality in any of the suppositions; so that when the vapours were dispelled, they were convinced of the delusion.

'When I survey my past life,' he wrote in 1777, 'I discover nothing but a barren waste of time, with some disorders of body and disturbances of the mind very near to madness.' Pr. and Med., p. 1 55. Reynolds recorded that 'what Dr. Johnson said a few days before his death of his disposition to insanity was no new discovery to those who were intimate with him.' Taylor's Reynolds, ii. 455.
