This projection of words originally descriptive of the human body or of its activities into the objective world of Nature finds its richest illustrations in poetry,[B] where it may be held to represent less the elaborate artifice of a cultured mind than one of the most primitive tendencies of that mind powerfully swayed by emotion. Yet the process belongs equally to the more prosaic efforts which man puts forth to utilize the objects of his environment in the interests of self-maintenance. One of the earliest of these is seen in the use of words describing parts of the body to facilitate the description of the external world in its numerical aspects. Thus the Chinese use for "two" certain syllables (_ny_ and _ceul_) which originally mean "ears," the Hottentots employing the word for "hand" in the same sense. In middle high German the word for "sheaf" (_Schock_) signifies sixty, and is applied in that sense to all kinds of objects. The Letts, owing to their habit of throwing fish three at a time, employ the word _mettens_, "a throw," in the sense of "three." Among the same people flounders are tied in lots of thirty, whence has arisen the practice of designating thirty by the word _kahlis_, meaning "cord." The Quichuas attach the significance of ten to the word _chuncu_, "heap." The Gallas word for "half" has been traced to the verb _chaba_, "to break," and is the equivalent of our own word "fraction." So in a large number of languages the term for hand signifies "five," "two hands" meaning ten, and "man" ("two hands and two feet") twenty.
A like origin must be claimed for the measures of space and weight needed by man in his industrial and commercial activities. The finger, the thumb, the hand, the palm, the forearm, the foot--the extended arms, as in the ancient _orgya_, and the extended legs, as in the modern yard--have all played a fundamental part in determining the standard measures of the civilized world. To the same class belong the [Greek: gyê], the extent of field that could be worked by a laborer in one day; the _stade_, the distance which a good runner could traverse without stopping to take rest; also measures of time, such as the old division of the day based on the length of a man's shadow.
