The remarks made above, are susceptible of extensive generalization. Mr. Stuart says, in the third volume of his Elements of the Philosophy of Mind, "In one of our most celebrated universities, which has long enjoyed the proud distinction of being the principal seat of mathematical learning in this Island, I have been assured, that if at any time a spirit of fanaticism has infected (as will occasionally happen in all numerous societies,) a few of the unsounder limbs of that learned body, the contagion has invariably spread much more widely among the mathematicians, than among the men of erudition. Even the strong head of Waering, undoubtedly one of the ablest analysts that England has produced, was not proof against the malady; and he seems at last (as I am told by the late Dr. Watson, Bishop of Landaff,) to have sunk into a deep religious melancholy, approaching to insanity. When Whitefield first visited Scotland, and produced, by his powerful though unpolished eloquence, such marvellous effects on the minds of his hearers, Dr. Simpson, the celebrated professor of mathematics at Glasgow, had the curiosity to attend one of his sermons in the fields, but could never be persuaded, by all the entreaties of his friends, to hear another. He had probably felt his imagination excited in an unpleasant degree, and with his usual good sense resolved not to subject himself to the danger of a second experiment." Now it is well known, that mathematical studies exercise the imagination less perhaps than any other whatever; and the powerful influence spoken of by Mr. Stewart, was no doubt owing to the fact, that the individuals in question, had no control over the imagination; when once excited, they had never learned to manage and restrain it. Upon the same principles we can explain the wonderful control which the coquette ultimately acquires over all her feelings. The general opinion is, that coquettes are cold and feelingless, and have always been so, and that all their demonstrations of emotion, are the result of hypocrisy. This may sometimes be the case, but not always. Persons of this description, may even have intense feelings; but from constantly watching, restraining and curbing them, after they have been called into action, they acquire perfect mastery over them. In some cases, the feelings may be so chained down by habit, as almost to be destroyed; in fact, this is generally the case with coquettes, and when they do marry, it is frequently more from policy than love. Ambition and vanity, in their case, triumph eventually over love and feeling; and the love of riches, standing, pomp, and show, determines their choice.[5] There is one species of coquetry for which I have much compassion and sympathy; it is where the affections of a lady have really been won by an individual, whom prudence and the advice of friends, will forever prevent her from marrying. In this case it sometimes happens, that tenderness on her part, and a desire to avoid
