3.   I think these views further explain what has sometimes been noticed namely that we know nothing about the origin or history of any of our domestic breeds. But, in fact, a breed, like a dialect of a language, can hardly be said to have had a definite origin. A man preserves and breeds from an individual with some slight deviation of structure, or takes more care than usual in matching his best animals and thus improves them, and the improved individuals slowly spread in the immediate neighbourhood. But as yet they will hardly have a distinct name, and from being only slightly valued, their history will be disregarded. When further improved by the same slow and gradual process, they will spread more widely, and will get recognised as something distinct and valuable, and will then probably first receive a provincial name. In semi-civilised countries, with little free communication, the spreading and knowledge of any new sub-breed will be a slow process. As soon as the points of value of the new sub-breed are once fully acknowledged, the principle, as I have called it, of unconscious selection will always tend, perhaps more at one period than at another, as the breed rises or falls in fashion, perhaps more in one district than in another, according to the state of civilisation of the inhabitants slowly to add to the characteristic features of the breed, whatever they may be. But the chance will be infinitely small of any record having been preserved of such slow, varying, and insensible changes.I must now say a few words on the circumstances, favourable, or the reverse, to man's power of selection. A high degree of variability is obviously favourable, as freely giving the materials for selection to work on; not that mere individual differences are not amply sufficient, with extreme care, to allow of the accumulation of a large amount of modification in almost any desired direction. But as variations manifestly useful or pleasing to man appear only occasionally, the chance of their appearance will be much increased by a large number of individuals being kept; and hence this comes to be of the highest importance to success. On this principle Marshall has remarked, with respect to the sheep of parts of Yorkshire, that 'as they generally belong to poor people, and are mostly in small lots, they never can be improved.' On the other hand, nurserymen, from raising large stocks of the same plants, are generally far more successful than amateurs in getting new and valuable varieties. The keeping of a large number of individuals of a species in any country requires that the species should be placed under favourable conditions of life, so as to breed freely in that country. When the individuals of any species are scanty, all the individuals, whatever their quality may be, will generally be allowed to breed, and this will effectually prevent selection. But probably the most important point of all, is, that the animal or plant should be so highly useful to man, or so much valued by him, that the closest attention should be paid to even the slightest deviation in the qualities or structure of each individual. Unless such attention be paid nothing can be effected. I have seen it gravely remarked, that it was most fortunate that the strawberry began to vary just when gardeners began to attend closely to this plant. No doubt the strawberry had always varied since it was cultivated, but the slight varieties had been neglected. As soon, however, as gardeners picked out individual plants with slightly larger, earlier, or better fruit, and raised seedlings from them, and again picked out the best seedlings and bred from them, then, there appeared (aided by some crossing with distinct species) those many admirable varieties of the strawberry which have been raised during the last thirty or forty years.In the case of animals with separate sexes, facility in preventing crosses is an important element of success in the formation of new races, at least, in a country which is already stocked with other races. In this respect enclosure of the land plays a part. Wandering savages or the inhabitants of open plains rarely possess more than one breed of the same species. Pigeons can be mated for life, and this is a great convenience to the fancier, for thus many races may be kept true, though mingled in the same aviary; and this circumstance must have largely favoured the improvement and formation of new breeds. Pigeons, I may add, can be propagated in great numbers and at a very quick rate, and inferior birds may be freely rejected, as when killed they serve for food. On the other hand, cats, from their nocturnal rambling habits, cannot be matched, and, although so much valued by women and children, we hardly ever see a distinct breed kept up; such breeds as we do sometimes see are almost always imported from some other country, often from islands. Although I do not doubt that some domestic animals vary less than others, yet the rarity or absence of distinct breeds of the cat, the donkey, peacock, goose, &c., may be attributed in main part to selection not having been brought into play: in cats, from the difficulty in pairing them; in donkeys, from only a few being kept by poor people, and little attention paid to their breeding; in peacocks, from not being very easily reared and a large stock not kept; in geese, from being valuable only for two purposes, food and feathers, and more especially from no pleasure having been felt in the display of distinct breeds.To sum up on the origin of our Domestic Races of animals and plants. I believe that the conditions of life, from their action on the reproductive system, are so far of the highest importance as causing variability. I do not believe that variability is an inherent and necessary contingency, under all circumstances, with all organic beings, as some authors have thought. The effects of variability are modified by various degrees of inheritance and of reversion. Variability is governed by many unknown laws, more especially by that of correlation of growth. Something may be attributed to the direct action of the conditions of life. Something must be attributed to use and disuse. The final result is thus rendered infinitely complex. In some cases, I do not doubt that the intercrossing of species, aboriginally distinct, has played an important part in the origin of our domestic productions. When in any country several domestic breeds have once been established, their occasional intercrossing, with the aid of selection, has, no doubt, largely aided in the formation of new sub-breeds; but the importance of the crossing of varieties has, I believe, been greatly exaggerated, both in regard to animals and to those plants which are propagated by seed. In plants which are temporarily propagated by cuttings, buds, &c., the importance of the crossing both of distinct species and of varieties is immense; for the cultivator here quite disregards the extreme variability both of hybrids and mongrels, and the frequent sterility of hybrids; but the cases of plants not propagated by seed are of little importance to us, for their endurance is only temporary. Over all these causes of Change I am convinced that the accumulative action of Selection, whether applied methodically and more quickly, or unconsciously and more slowly, but more efficiently, is by far the predominant power.

Ricciardo uttered these words, teares streaming aboundantly downehis cheekes, and Madame Catulla (all the while) likewise showred forthher sorrowes equally to his, now, although she was exceedinglytroubled in mind, and saw what her owne jealous folly had nowbrought her to, a shame beyond all other whatsoever: in the middest ofher tormenting passions, shee considered on the words of Ricciardo,found good reason in them, in regard of the unavoydable evilswhereupon shee thus spake. Ricciardo, I know not how to beare thehorrible injurie, and notorious treason used by thee against me, graceand goodnesse having so forsaken me, to let me fall in so foule amanner. Nor becommeth it me, to make any noyse or out-cry heere,whereto simplicity, or rather devillish jealousie, did conduct me. Butcertaine I am of one thing, that I shall never see any one joyfullday, till (by one meanes or other) I bee reverged on thee. Thou hastglutted thy desire with my disgrace, let me therefore go from thee,never more to looke upon my wronged husband, or let any honest womanever see my face.

Her brown shoes peeped occasionally from beneathher skirt. She carried her gloves in her hand.

1. 三月间,明瑞到永昌,陆续调集满兵三千人、云贵和四川绿旗兵二万余人,于九月间分兵两路进攻。明瑞统率清军主力,出宛顶,经木邦,向缅甸首都阿瓦(今曼德勒附近)进军;命参赞大臣额尔登额率兵趋蛮莫(今八莫),沿伊洛瓦底江而下,在阿瓦会师。额尔登额在老官屯顿兵坚城之下,贻误战机。十二月,明瑞军攻破蛮结,屡遭缅军袭击,供应困难,却向朝廷报捷。次年正月,乾隆帝封授明瑞一等诚嘉义勇公,赏给黄带子。明瑞军转向勐笼就食,以待额尔登额军。缅军跟踪追击,明瑞率领清军取道大山土司、木邦土司回师,在木邦被缅军围困。额尔登额拥兵不救。云南巡抚鄂宁奏闻,乾隆帝命将额尔登额押解来京,并传渝明瑞突围退兵。明瑞在蛮化设伏击败缅甸军,间道出波竜铜厂,急向云南境内撤退。缅甸军不断增援,二月初十日在小勐育结集四、五万人,包围清军。明瑞命诸将在夜间带兵突围,自领亲兵数百名断后。两军激战,清领队大臣扎拉丰阿阵亡,领队大臣观音保自刎,明瑞身负重伤,在军中自缢死。清军损失惨重。
2.   "I think, Inspector," Holmes remarked, "that you would do well totelegraph for an escort, as, if my calculations prove to be correct,you may have a particularly dangerous prisoner to convey to the countyjail. The boy who takes this note could no doubt forward yourtelegram. If there is an afternoon train to town, Watson, I think weshould do well to take it, as I have a chemical analysis of someinterest to finish, and this investigation draws rapidly to a close."When the youth had been dispatched with the note, Sherlock Holmesgave his instructions to the servants. If any visitor were to callasking for Mrs. Hilton Cubitt, no information should be given as toher condition, but he was to be shown at once into the drawing-room.He impressed these points upon them with the utmost earnestness.Finally he led the way into the drawing-room, with the remark that thebusiness was now out of our hands, and that we must while away thetime as best we might until we could see what was in store for us. Thedoctor had departed to his patients, and only the inspector and myselfremained.

2. 在第II部类商品产品的价值中,v+m这一组成部分还要加以研究。考察这个组成部分,同我们在这里研究的最重要的问题无关。我们研究的问题是:每个单个资本主义商品产品的价值分为c+v+m的这种分割,即使以不同的表现形式作为媒介,在什么程度内同样也适用于全部年产品的价值。这个问题,一方面通过I(v+m)和IIc的交换来解决,另一方面通过我们以后对第I部类年商品产品中Ic的再生产的研究来解决。既然II(v+m)以消费品的实物形式存在,既然第II部类为支付劳动力报酬而预付给工人的可变资本,总的来说要由工人用于消费资料,既然在简单再生产的前提下,商品价值的m部分实际上作为收入用于消费资料,那末,显而易见,第II部类的工人用他们从第II部类的资本家那里得到的工资,买回他们自己产品中与他们以工资形式得到的货币价值的数量相当的一部分。因此,第II部类的资本家就把他们为支付劳动力报酬而预付的货币资本再转化为货币形式;这完全好象他们付给工人的只不过是一种价值符号。一旦工人通过购买他们自己生产的、但属于资本家的商品产品的一部分,来实现这种价值符号,这种价值符号就会回到资本家手中,不过,这种符号在这里不仅代表价值,而且也在它自己的金身或银身中具有这种价值。指金属货币。如果是纸币就仅仅代表价值,而本身不具有这种价值。以货币形式预付的可变资本,是通过工人阶级作为买者和资本家阶级作为卖者出现的过程而流回的,关于这种回流,我们以后还要

      We had a quiet day. No company, a walk, a family dinner of four, and an evening of looking over books and pictures; Miss Murdstone with a homily before her, and her eye upon us, keeping guard vigilantly. Ah! little did Mr. Spenlow imagine, when he sat opposite to me after dinner that day, with his pocket-handkerchief over his head, how fervently I was embracing him, in my fancy, as his son-in law! Little did he think, when I took leave of him at night, that he had just given his full consent to my being engaged to Dora, and that I was invoking blessings on his head!
