鸟类的

Most Birds mate by joining their cloacas in a "cloacal kiss"; muscular contractions transfer the sperm from the male to the female.

但多数鸟类仅以泄殖腔互相接触，藉肌肉收缩而把雄鸟的精子送给雌鸟。有胎盘哺乳动物及多数硬骨鱼无泄殖腔。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
