--good blood, bad blood, proud blood, humble blood, honest blood, thieving blood, heroic blood, cowardly blood. The tendency may skip a generation or two, but it is sure to come out, as in a little child you sometimes see a similarity to a great-grandfather whose picture hangs on the wall. That the physical and mental and moral qualities are inheritable is patent to any one who keeps his eyes open. The similarity is so striking sometimes as to be amusing. Great families, regal or literary, are apt to have the characteristics all down through the generations, and what is more perceptible in such families may be seen on a smaller scale in all families. A thousand years have no power to obliterate the difference. ROYAL RASCALS. The large lip of the House of Austria is seen in all the generations, and is called the Hapsburg lip. The House of Stuart always means in all generations cruelty and bigotry and sensuality. Witness Queen of Scotts. Witness Charles I. and Charles II. Witness James I. and James II. and all the other scoundrels of that imperial line. Scottish blood means persistence, English blood means reverence for the ancient, Welsh blood means religiosity, Danish blood means fondness for the sea, Indian blood means roaming disposition, Celtic blood means fervidity, Roman blood means conquest. The Jewish facility for accumulation you may trace clear back to Abraham, of whom the Bible says "he was rich in silver and gold and cattle," and to Isaac and Jacob, who had the same FAMILY CHARACTERISTICS. Some families are characterized by longevity, and they have a tenacity of life positively Methuselahish. Others are characterized by Goliathian stature, and you can see it for one generation, two generations, five generations, in all the generations. Vigorous theology runs on in the line of the Alexanders. Tragedy runs on in the family of the Kembles. Literature runs on in the line of the Trollopes. Philanthropy runs on in the line of the Wilberforces. Statesmanship runs on in the line of the Adamses. Henry and Catharine of Navarre religious, all their families religious. The celebrated family of the Casini, all mathematicians. The celebrated family of the Medici--grandfather, son and Catharine--all remarkable for keen intellect. The celebrated family of Gustavus Adolphus, all warriors. This law of heredity asserts itself without reference to social or political condition, for you sometimes find the ignoble in high place and the honorable in obscure place. A descendant of Edward I. a toll gatherer. A descendant of Edward III. a door-keeper. A descendant of the Duke of Northumberland a trunk-maker. Some of the mightiest families of England are extinct, while some of those most honored in the peerage go back to an ancestry of hard knuckles and rough exterior. This law of heredity entirely independent of social or political condition.
