Life with Boswell
Dr Tissot had been recommended to Boswell by David Dalrymple, and he consulted him on May 24, 1764, describing him as "a true original, a shrewd, lively little fellow of sixty". Boswell visited the Utrecht Bedlam with Tissot on May 29, on which occasion Tissot stated that "mankind were all mad and differed only in degrees". (Boswell in Holland, p. 256)
