四足动物的

Some quadrupeds are not housesbecomes, by contraposition, Some thing not house are quadrupeds.

某些四足动物不是马，以反言论法，变成了某些不是马的东西是四足动物。

Bloodless and many footed animals, whether furnished with wings or feet, move with more than four points of motion; as, for instance, the dayfly moves with four feet and four wings: and, I may observe in passing, this creature is exceptional not only in regard to the duration of its existence, whence it receives its name, but also because though a quadruped it has wings also.

无血多足动物，不管装备翅膀还是足，移动依靠多于四个的运动点：像是，例如，蜉蝣依靠四足和四翅膀活动：并且，我可以顺便说一下，这种生物的特别不仅与它的生存周期、名称的由来有关，也因为它尽管是四足动物，但是也有翅膀。

The first is what are the fewest points of motion necessary to animal progression, the second why sanguineous animals have four points and not more, but bloodless animals more than four, and generally why some animals are footless, others bipeds, others quadrupeds, others polypods, and why all have an even number of feet, if they have feet at all; why in fine the points on which progression depends are even in number.

首先是运动是什么必要的动物进展最低分，第二个为什么血红的动物有四点意见，而不是多，但不流血的动物超过4，一般为什么一些动物是无足，其他两足动物，其他四足动物，其他polypods ，为什么都有一个偶数的脚，如果他们在所有的脚，为什么在精细点上的进展取决于更是增多。

Whereas the proximal part of the tetrapod limb skeleton can easily be homologized with the paired fin skeletons of sarcopterygian (lobe-finned) fish, there has been much debate about the origin of digits.

早期的假设认为，四足动物的足趾与鱼类的放射鳍同源，但根据发育研究结果，同时根据一种名叫&潘氏鱼&、与陆地脊椎动物密切相关的目前已经灭绝的鱼（这种鱼似乎没有末梢的趾状放射鳍）的鳍，这一观点似乎并不可靠。

And they concluded that fingers were pretty much invented by the first tetrapods: that is, critters with four limbs.

他们得出结论：手指基本上是第一个四足动物的发明。

WASHINGTON - Scientists unearthed a skull of the most primitive four-legged creature in Earth's history, which should help them better understand the evolution of fish to advanced animals that walk on land. The 365 million-year-old fossil skull, shoulders and part of the pelvis of the water-dweller, Ventastega curonica, were found in Latvia, researchers report in a study published in Thursday's issue of the journal Nature. Even though Ventastega is likely an evolutionary dead-end, the finding sheds new details on the evolutionary transition from fish to tetrapods. Tetrapods are animals with four limbs and include such descendants as amphibians, birds and mammals.

华盛顿-科学家挖掘出一副地球历史上最原始的四足生物头骨，这个有利于帮组他们更好理解鱼类进化成为更先进的陆地行走生物，这个有着三亿六千五百万年年龄的头骨，肩膀和水生生物的一部分骨盆，Ventastega curonica，在Latvia被发现，研究者一篇研究报告发表在在星期三出版的自然杂志上，尽管Ventastega 可能是一个进化的死胡同，这个发现给出了从鱼类到四足动物进化变迁过程的新细节，四足动物是使用四肢的动物并且包括下属的比如两栖类动物，鸟类和哺乳类动物。

We found that Rhodnius prolixus, a triatomine bug feeding on the blood of various tetrapods and vector of Chagas' disease in humans, carries in its genome four distinct transposon families that also invaded the genomes of a diverse, but overlapping, set of tetrapods.

具体来说，长红锥蝽（一种以四足动物血液为食、是人类锥虫病传播媒介的虫子）的基因组中有四个截然不同的转位子家族，它们入侵包括负鼠和松鼠猴在内的一系列不同四足动物的基因组。

A fast running motion of other quadrupeds.

其它四足动物的快速奔跑

All creatures that are capable of motion move with four or more points of motion; the blooded animals with four only: as, for instance, man with two hands and two feet, birds with two wings and two feet, quadrupeds and fishes severally with four feet and four fins.

所有能够运动的动物都有四个或更多的运动触点；有血动物只有四个：像是，例如，人有两手和两脚，鸟有两翅和两足，四足动物和鱼各自有四足和四鳍。

Under the diaphragm on the right-hand side lies the ''liver'',and on the left-hand side the ''spleen'', alike in all animals thatway; for, be it observed, in some quadrupeds these organs have beenfound in a transposed position.

在隔膜的下方右手是肝脏，左手是脾脏，在所有正常情况下拥有这些器官的动物中都相同；因为，仔细观察，这些器官在某些四足动物的身体中被改换了位置。
