I find also, in the thirteenth chapter, an unexplained allusion. There my husband says, "Just ask my brother his experience in regard of the word to which you object." The word was _stomach_, at the use of which I had in my ill-temper taken umbrage: however disagreeable a word in itself, surely a husband might, if need be, use it without offence. It will be proof enough that my objection arose from pure ill-temper when I state that I have since asked Roger to what Percivale referred. His reply was, that, having been requested by a certain person who had a school for young ladies--probably she called it a college--to give her pupils a few lectures on physiology, he could not go far in the course without finding it necessary to make a not unfrequent use of the word, explaining the functions of the organ to which the name belonged, as resembling those of a mill. After the lecture was over, the school-mistress took him aside, and said she really could not allow her young ladies to be made familiar with such words. Roger averred that the word was absolutely necessary to the subject upon which she had desired his lectures; and that he did not know how any instruction in physiology could be given without the free use of it. "No doubt," she returned, "you must recognize the existence of the organ in question; but, as the name of it is offensive to ears polite, could you not substitute another? You have just said that its operations resemble those of a mill: could you not, as often as you require to speak of it, refer to it in the future as _the mill_?" Roger, with great difficulty repressing his laughter, consented; but in his next lecture made far more frequent reference to _the mill_ than was necessary, using the word every time--I know exactly how--with a certain absurd solemnity that must have been irresistible. The girls went into fits of laughter at the first utterance of it, and seemed, he said, during the whole lecture, intent only on the new term, at every recurrence of which their laughter burst out afresh. Doubtless their school-mistress had herself prepared them to fall into Roger's trap. The same night he received a note from her, enclosing his fee for the lectures given, and informing him that the rest of the course would not be required. Roger sent back the money, saying that to accept part payment would be to renounce his claim for the whole; and that, besides, he had already received an amount of amusement quite sufficient to reward him for his labor. I told him I thought he had been rather cruel; but he said such a woman wanted a lesson. He said also, that to see the sort of women who sometimes had the responsibility of training girls must make the angels weep; none but a heartless mortal like himself could laugh where conventionality and insincerity were taught in every hint as to posture and speech. It was bad enough, he said, to shape yourself into your own ideal;
