The Specific Gravity of the Insane Brain

  • Francis O. Simpson (a1)
Extract

This paper is only intended to be a preliminary note upon the specific gravity of the brain in the insane, and contains the results of experiments upon thirty cases conducted at the West Riding Asylum, Wakefield, during the early part of this year. Over 1400 investigations have been made upon these brains, and as the inclusion of data from different parts of the country might cause scientific inaccuracies, it has been thought advisable to publish the present results separately, prior to the initiation of a further series of experiments.

Since writing this paper I have had my attention directed to a method by Dr. Robert S. Cook, in which osmic acid was used as a fixative, and have repeated my experiments with osmic acid, which has failed as before to produce a good Nissl preparation.

Prepared for the Annual Meeting of the Medico-Psychological Association, Edinburgh, 1898.
