At the end of that time he re-entered the high sohool, and even took his place with his former olass, passing a good examination on the very matters ic which he had failed so completely in recitation, nature having merely " let up'' sufficiently in his growth to allow some share of nourishment, to his brain. The last oase oi this kind that I shall quote has just occurred in my own family, and I have thus had twice as much oppor tunity for observation. One of my sons inoreasad in height and bulk very rapidly, and now, though only four teen last February, measures five feet seven inches, and weighs 142 pounds. Somewhat more than a year ago he began to be very lazy. His lessons were not prepared, he complained oi headaches and of not feeling well, yet when sent home for such reasons he had no difficulty in playing ball in the fields near our house, and was often found in a pleasant corner reading a pleasant book. He appeared to have no compunctions of conscience, and his mother en 1 myself were very much distressed on this account. It was very difficult to get him up iu the morning, and he displayed generally the same utter sluggishness and listlessness that had distinguished Harry N. He forgot messages so easily that he was of lees use to us than the younger children, and we were obliged to get along with him generally as well as wo oould. He took such a loathing to all studies or tasks of any kind that at length I concluded to let them all go. I told him frankly that I considered him to be a sick boy, and that I must wait patiently until he got well. I said I should in the meantime employ him as my olerk or to assist me in any way that he oould. In his case two other passing diseases, self-sufficiency and the sea fever, added their complications. As to the first, I have for many years been convinced that sixteen is about the wisest age. A boy generally has at that age more sure and certain knowledge than he has ever ha/d before or ever will have again.
