I have treated the subject of the Chemistry of the Brain at considerable length in my treatise on "Aphasia and the Localisation of Articulate Language," to which book I would refer those who desire further information in reference to the connection between the amount of phosphorus and intellectual vigour. FOOTNOTES: [5] The question of the influence of alcoholic stimulants on the development of mental disease formed a prominent feature in the proceedings of this congress, and it is also a subject which is just now engaging the attention of pathologists in all parts of the world.

[7] Toussenel, a French writer, says "La plupart des idiots sont des enfants procréés dans l'ivresse bacchique. On sait que les enfants se ressentent généralement de l'influence passionelle qui a présidé à leur conception." At a discussion at the Obstetrical Society, Dr. Langdon Down is reported to have entertained similar views. [8] I would refer those who may wish to pursue the inquiry as to the baneful influence of alcohol on the human frame, to the celebrated Cantor Lectures on Alcohol, by my friend Sir B.W. Richardson, in which he introduces the physiological argument into the temperance cause, asserting that alcohol cannot be classified as a food; that degeneration of tissues is produced, that it neither supplies matter for construction nor production of heat, but, on the contrary, militates against both. Sir B.W. Richardson's latest views upon this subject are developed in the pages of the "Hospital" for February 1st and March 14th, of this present year. In France, M. Lunier, Inspector of Asylums, has shown that the departments in which the consumption of alcohol had increased most, were those in which there had been a corresponding increase of insanity, and this was shown most strikingly in regard to women, at the period when the natural wines of the country gave way to the consumption of spirits. In Sweden, Dr. Westfelt has lately made a communication to the Stockholm Medical Society, containing the statistics of alcoholic abuse and its results in Sweden. He calculates that at least from 7 to 12 or 13 per cent. among males, and from 1 to 2 per cent. among females, of all cases of acquired insanity, are due to the abuse of alcohol; and in reference to its influence on progeny and race, he shows that a steady diminution of the population was coincident with a period when drunkenness was at its greatest height.
