One of the subjects of the following remarks, J. R—, was shown at the Spring Meeting of the Scottish Branch of the Medico-Psychological Association, held at Gartloch Asylum in March, 1910. This case is reported in the Journal of Mental Science for July of that year. The other patient, J. S—, came under my care in May, 1910, and his history is so far unrecorded. As there are many points of similarity in the two cases, it will save time to describe them together in so far as they resemble one another, and then later to indicate the differences between the two.
