1. 这时的阿拉伯半岛,在文明邻邦的眼中,是游牧蛮族的偏僻之壤。然而,6世纪后半叶,由于商路的改变,它已成为经济要地。埃及的混乱和拜占廷-波斯战争,使传统的红海至尼罗河流域和波斯湾至红侮的道路无法通行。商人们因此转向更加艰难,但却较为安全的道路,即从叙利亚经阿拉伯半岛西部到也门,再从也门用船只往返于印度洋之间运输货物。麦加因商路的改变而获利,它地处商路中段、阿拉伯半岛沿岸,是北往叙利亚,南通也门,东到波斯湾,西至红海吉达港和走水路前往非洲的交通枢纽。

4. 1。长安城西汉长安城是自商周以来规模最大的城市。长安城位于今陕西西安城西北约10公里处渭水南岸的台地上,城市平面大体近似方形,地势南高北低,总面积约为36平方公里。最初汉高祖刘邦就秦朝的离宫兴乐宫遗址兴建长乐宫,在其西又建未央宫和北宫。长乐、未央宫是西汉长安城内最主要的两个宫殿区。据考古勘测,未央宫的宫墙周围近9公里,长乐宫的宫墙周围超过10公里,仅这两处宫殿,即已占据主城面积的1/2,此外,还有东阙、北阙、武库、太仓等宫殿,其壮丽豪华的程度竟使刘邦发出责词,而主持兴建的萧何的非壮丽亡以重威的答词又使刘邦由怒转为满心欢喜,心安理得。汉武帝仍不以此为满足,又兴建了未央宫北的桂宫、长乐宫北的明光宫和城外的上林苑,内有宫观数十,最大者为建章宫。据文献记载,这时的长安城内还有九市和一百六十闾分布于地势低洼的城的北阪。王莽时代在长安城外的南郊还建有十几个规模巨大的礼制建筑。汉长安城城墙全部为版筑的夯土墙,墙基底厚16米,原高度因颓圮不明,现存高度达7米以上。城的方向基本为正南北,前面城墙约长6公里,周长25。1公里,合汉代60里强,前面三个城门,四面共十二个城门。城门为骑楼式建筑,即在城墙上预留阙口,在两侧沿边密排几对柱础石,上立木柱,再在其上建筑城门楼,与后代的拱券式城门有别。由城门通向城内的道路都是三条,中间一条最宽,称驰道、御道,属皇帝专用。其中贯通南北的西安门内大街长5公里半,这条街宽约50米,御道宽20米。由于长安城系秦旧宫多次扩建而成,受渭水影响,城墙随渭河多次转折,呈一不规则方形,城内总体也未规矩对称,未能充分达到理想的效果。但其布局已受《考工记》前朝后市、旁九门等都市设计布局的影响,开始向规整化过渡。

5.   Alph. De Candolle and others have shown that plants which have very wide ranges generally present varieties; and this might have been expected, as they become exposed to diverse physical conditions, and as they come into competition (which, as we shall hereafter see, is a far more important circumstance) with different sets of organic beings. But my tables further show that, in any limited country, the species which are most common, that is abound most in individuals, and the species which are most widely diffused within their own country (and this is a different consideration from wide range, and to a certain extent from commonness), often give rise to varieties sufficiently well-marked to have been recorded in botanical works. Hence it is the most flourishing, or, as they may be called, the dominant species, those which range widely over the world, are the most diffused in their own country, and are the most numerous in individuals, which oftenest produce well-marked varieties, or, as I consider them, incipient species. And this, perhaps, might have been anticipated; for, as varieties, in order to become in any degree permanent, necessarily have to struggle with the other inhabitants of the country, the species which are already dominant will be the most likely to yield offspring which, though in some slight degree modified, will still inherit those advantages that enabled their parents to become dominant over their compatriots.If the plants inhabiting a country and described in any Flora be divided into two equal masses, all those in the larger genera being placed on one side, and all those in the smaller genera on the other side, a somewhat larger number of the very common and much diffused or dominant species will be found on the side of the larger genera. This, again, might have been anticipated; for the mere fact of many species of the same genus inhabiting any country, shows that there is something in the organic or inorganic conditions of that country favourable to the genus; and, consequently, we might have expected to have found in the larger genera, or those including many species, a large proportional number of dominant species. But so many causes tend to obscure this result, that I am surprised that my tables show even a small majority on the side of the larger genera. I will here allude to only two causes of obscurity. Fresh-water and salt-loving plants have generally very wide ranges and are much diffused, but this seems to be connected with the nature of the stations inhabited by them, and has little or no relation to the size of the genera to which the species belong. Again, plants low in the scale of organisation are generally much more widely diffused than plants higher in the scale; and here again there is no close relation to the size of the genera. The cause of lowly-organised plants ranging widely will be discussed in our chapter on geographical distribution.From looking at species as only strongly-marked and well-defined varieties, I was led to anticipate that the species of the larger genera in each country would oftener present varieties, than the species of the smaller genera; for wherever many closely related species (i.e. species of the same genus) have been formed, many varieties or incipient species ought, as a general rule, to be now forming. Where many large trees grow, we expect to find saplings. Where many species of a genus have been formed through variation, circumstances have been favourable for variation; and hence we might expect that the circumstances would generally be still favourable to variation. On the other hand, if we look at each species as a special act of creation, there is no apparent reason why more varieties should occur in a group having many species, than in one having few.
6.   The nature of the bond of correlation is very frequently quite obscure. M. Is. Geoffroy St Hilaire has forcibly remarked, that certain malconformations very frequently, and that others rarely coexist, without our being able to assign any reason. What can be more singular than the relation between blue eyes and deafness in cats, and the tortoise-shell colour with the female sex; the feathered feet and skin between the outer toes in pigeons, and the presence of more or less down on the young birds when first hatched, with the future colour of their plumage; or, again, the relation between the hair and teeth in the naked Turkish dog, though here probably homology comes into play? With respect to this latter case of correlation, I think it can hardly be accidental, that if we pick out the two orders of mammalia which are most abnormal in their dermal coverings, viz. Cetacea (whales) and Edentata (armadilloes, scaly ant-eaters, &c.), that these are likewise the most abnormal in their teeth.

3.   These propositions will be most readily understood by looking to our domestic races. The most distinct breeds of pigeons, in countries most widely apart, present sub-varieties with reversed feathers on the head and feathers on the feet, characters not possessed by the aboriginal rock-pigeon; these then are analogous variations in two or more distinct races. The frequent presence of fourteen or even sixteen tail-feathers in the pouter, may be considered as a variation representing the normal structure of another race, the fantail. I presume that no one will doubt that all such analogous variations are due to the several races of the pigeon having inherited from a common parent the same constitution and tendency to variation, when acted on by similar unknown influences. In the vegetable kingdom we have a case of analogous variation, in the enlarged stems, or roots as commonly called, of the Swedish turnip and Ruta baga, plants which several botanists rank as varieties produced by cultivation from a common parent: if this be not so, the case will then be one of analogous variation in two so-called distinct species; and to these a third may be added, namely, the common turnip. According to the ordinary view of each species having been independently created, we should have to attribute this similarity in the enlarged stems of these three plants, not to the vera causa of community of descent, and a consequent tendency to vary in a like manner, but to three separate yet closely related acts of creation.With pigeons, however, we have another case, namely, the occasional appearance in all the breeds, of slaty-blue birds with two black bars on the wings, a white rump, a bar at the end of the tail, with the outer feathers externally edged near their bases with white. As all these marks are characteristic of the parent rock-pigeon, I presume that no one will doubt that this is a case of reversion, and not of a new yet analogous variation appearing in the several breeds. We may I think confidently come to this conclusion, because, as we have seen, these coloured marks are eminently liable to appear in the crossed offspring of two distinct and differently coloured breeds; and in this case there is nothing in the external conditions of life to cause the reappearance of the slaty-blue, with the several marks, beyond the influence of the mere act of crossing on the laws of inheritance.
