1.   In man's methodical selection, a breeder selects for some definite object, and free intercrossing will wholly stop his work. But when many men, without intending to alter the breed, have a nearly common standard of perfection, and all try to get and breed from the best animals, much improvement and modification surely but slowly follow from this unconscious process of selection, notwithstanding a large amount of crossing with inferior animals. Thus it will be in nature; for within a confined area, with some place in its polity not so perfectly occupied as might be, natural selection will always tend to preserve all the individuals varying in the right direction, though in different degrees, so as better to fill up the unoccupied place. But if the area be large, its several districts will almost certainly present different conditions of life; and then if natural selection be modifying and improving a species in the several districts, there will be intercrossing with the other individuals of the same species on the confines of each. And in this case the effects of intercrossing can hardly be counterbalanced by natural selection always tending to modify all the individuals in each district in exactly the same manner to the conditions of each; for in a continuous area, the conditions will generally graduate away insensibly from one district to another. The intercrossing will most affect those animals which unite for each birth, which wander much, and which do not breed at a very quick rate. Hence in animals of this nature, for instance in birds, varieties will generally be confined to separated countries; and this I believe to be the case. In hermaphrodite organisms which cross only occasionally, and likewise in animals which unite for each birth, but which wander little and which can increase at a very rapid rate, a new and improved variety might be quickly formed on any one spot, and might there maintain itself in a body, so that whatever intercrossing took place would be chiefly between the individuals of the same new variety. A local variety when once thus formed might subsequently slowly spread to other districts. On the above principle, nurserymen always prefer getting seed from a large body of plants of the same variety, as the chance of intercrossing with other varieties is thus lessened.Even in the case of slow-breeding animals, which unite for each birth, we must not overrate the effects of intercrosses in retarding natural selection; for I can bring a considerable catalogue of facts, showing that within the same area, varieties of the same animal can long remain distinct, from haunting different stations, from breeding at slightly different seasons, or from varieties of the same kind preferring to pair together.

6.   Hurstwood made arrangements with one of the instalment houseswhereby they furnished the flat complete and accepted fiftydollars down and ten dollars a month. He then had a littleplate, bearing the name G. W. Wheeler, made, which he placed onhis letter-box in the hall. It sounded exceedingly odd to Carrieto be called Mrs. Wheeler by the janitor, but in time she becameused to it and looked upon the name as her own.


1.   "I am not surprised, my dear mother, at your displeasure," repliedTelemachus, "I understand all about it and know when things are not asthey should be, which I could not do when I was younger; I cannot,however, behave with perfect propriety at all times. First one andthen another of these wicked people here keeps driving me out of mymind, and I have no one to stand by me. After all, however, this fightbetween Irus and the stranger did not turn out as the suitors meant itto do, for the stranger got the best of it. I wish Father Jove,Minerva, and Apollo would break the neck of every one of thesewooers of yours, some inside the house and some out; and I wish theymight all be as limp as Irus is over yonder in the gate of the outercourt. See how he nods his head like a drunken man; he has had sucha thrashing that he cannot stand on his feet nor get back to his home,wherever that may be, for has no strength left in him."

6. 伦乃造意,用树肤、麻头及敝布、鱼网以为纸。元兴六年(公元105年)奏上之,帝善其能,自是莫不从用焉,故天下咸称'蔡侯纸'.后世便以这段记载为根据,把蔡伦视为造纸的鼻祖,流传了1000多年。尽管西汉麻纸接二连三地被发现,表明蔡伦并不是纸的最早发明者。但他首先用树皮、麻头、废旧的麻布(当时的布是麻布,不是棉布)和鱼网等作原料,造出了适用于书写的优质纸张来。因此,尽管纸不是蔡伦所发明的,但他作为一位造纸术的杰出改革家,所立下的伟大功勋仍是巨大的,值得人们赞颂和怀念。
