2) It makes me melancholy to see how like fools some very sensible people act in the matter of choosing wives. They perplex their judgments by a most undue attention to little niceties of personal appearance, habits, disposition, and other trifles which concern nobody but the lady herself. An unhappy gentleman, resolving to wed nothing short of perfection, keeps his heart and hand till both get so old and withered that no tolerable woman will accept them. Now this is the very height of absurdity The true rule is to ascertain that the match is fundamentally a good one, and then to take it for granted that all minor objections, should there be such, will vanish, if you let them alone

3) Besides the fundamental principle already hinted at, I demanded the fresh bloom of youth, pearly teeth, glossy ringlets, and the whole list of lovely items, with the utmost delicacy of habits and sentiments, a silken texture of mind, and, above all, a virgin heart. In a word, if a young angel just from paradise, yet dressed in earthly fashion, had come and offered me her hand, it is by no means certain that I should have taken it. There was every chance of my becoming a most miserable old bachelor, when, by the best luck in the world, I made a journey into another state, and was smitten by, and smote again, and wooed, won, and married, the present Mrs. Bullfrog, all in the space of a fortnight. Owing to these extempore measures, I not only gave my bride credit for certain perfections which have not as yet come to light, but also overlooked a few trifling defects, which, however, glimmered on my perception long before the close of the honeymoon. Yet, as there was no mistake about the fundamental principle aforesaid, I soon learned, as will be seen, to estimate Mrs. Bullfrog's deficiencies and superfluities at exactly their proper value.
