If I had been by nature extremely quick of apprehension, or had possessed a very accurate and retentive memory or were of a remarkably active and energetic character, the trial would not be conclusive; but in all these natural gifts I am rather below than above par; what I could do, could assuredly be done by any boy or girl of average capacity and healthy physical constitution: and if I have accomplished anything, I owe it, among other fortunate circumstances, to the fact that through the early training bestowed on me by my father, I started, I may fairly say, with an advantage of a quarter of a century over my contemporaries.
