On the Somatic and Psychical Causes of Disease in the Structure and Functions of the Brain, viewed more particularly in reference to Marriages of Consanguinity as a great social evil.

Extract

Insanity, together with many other forms of disease affecting the brain, are doubtless upon the increase. Our statistical tables and periodical registers all clearly and unmistakeably tell us this. It is no advantage either to society at large, or to individuals composing that society, to try to beg the question. We cannot disprove the fact. Better, therefore, let us try to search out its causes, that, if possible, they may be removed. By taking this course, we shall sooner find our-selves in a more hopeful position for arresting the onward march of a formidable enemy to our national peace and prosperity.
