To convince men of the necessity of taking this method, let any one even below the skill of an astrologer, behold the turn of faces he meets as soon as he passes Cheapside Conduit, and you see a deep attention and a certain unthinking sharpness in every countenance. They look attentive, but their thoughts are engaged on mean purposes. To me it is very apparent, when I see a citizen pass by, whether his head is upon woollen, silks, iron, sugar, indigo, or stocks. Now this trace of thought appears or lies hid in the race for two or three generations. I know at this time a person of a vast estate, who is the immediate descendant of a fine gentleman, but the great grandson of a broker, in whom his ancestor is now revived. He is a very honest gentleman in his principles, but cannot for his blood talk fairly; he is heartily sorry for it; but he cheats by constitution, and over-reaches by instinct. The happiness of the man who marries my sister will be, that he has no faults to correct in her but her own, a little bias of fancy, or particularity of manners which grew in herself, and can be amended by her. From such an untainted couple we can hope to have our family rise to its ancient splendour of face, air, countenance, manner, and shape, without discovering the product of ten nations in one house. Obadiah Greenhat says, "he never comes into any company in England, but he distinguishes the different nations of which we are composed." There is scarce such a living creature as a true Briton. We sit down, indeed, all friends, acquaintance, and neighbours; but after two bottles you see a Dane start up and swear, "the kingdom is his own." A Saxon drinks up the whole quart, and swears he will dispute that with him. A Norman tells them both, he will assert his liberty; and a Welshman cries, "They are all foreigners and intruders of yesterday," and beats them out of the room. Such accidents happen frequently among neighbours' children, and cousin-germans. For which reason I say study your race, or the soil of your family will dwindle into cits or 'squires, or run up into wits or madmen. VI.--PROFESSIONAL: A CASE OF SPLEEN. White's Chocolate House, October 12. It will be allowed me that I have all along showed great respect in matters which concern the fair sex; but the inhumanity with which the author of the following letter has been used is not to be suffered:-- "Sir,
