Mr. President and Gentlemen,—The subject that I propose to bring to your notice to-day—namely, the hereditary transmission of epilepsy—is one of extreme interest and importance at the present time in this country, where, owing to recent legislation, public attention has been strongly focussed on the question of transmitted defect. The results that I have obtained have been a matter of considerable surprise to me, and I am anxious to obtain the experiences of others in this matter.
