In the July number of the “Journal of Mental Science” is a paper of considerable interest by Dr. Clouston on “Tumours of the Brain and their Relation to its Mental Functions.” Only a few cases are there recorded. The following contribution is submitted to the members of the Medico-Psychological Association:—

During my residence in the St. Marylebone Infirmary, in three years and a-half, there were in 1039 post-mortem examinations 22 cases of tumours of the brain; one of these was transferred to the insane ward, and two were in a state of fatuity, leaving 19, or at the rate of about 18-3 per thou sand, in whom no mental derangement was observed.
