It often happens that the composition of numeral words is less easily understood, and the original meanings more difficult to recover, than in the examples already given. But in searching for number systems which show in the formation of their words the influence of finger counting, it is not unusual to find those in which the derivation from native words signifying _finger, hand, toe, foot_, and _man_, is just as frankly obvious as in the case of the Zuni, the Arawak, the Eskimo, or the Montagnais scale. Among the Tamanacs,[74] one of the numerous Indian tribes of the Orinoco, the numerals are as strictly digital as in any of the systems already examined. The general structure of the Tamanac scale is shown by the following numerals: 5. amgnaitone = 1 hand complete. 6. itacono amgna pona tevinitpe = 1 on the other hand. 10. amgna aceponare = all of the 2 hands. 11. puitta pona tevinitpe = 1 on the foot. 16. itacono puitta pona tevinitpe = 1 on the other foot. 20. tevin itoto = 1 man. 21. itacono itoto jamgnar bona tevinitpe = 1 on the hands of another man. In the Guarani[75] language of Paraguay the same method is found, with a different form of expression for 20. Here the numerals in question are 5. asepopetei = one hand. 10. asepomokoi = two hands. 20. asepo asepi abe = hands and feet. Another slight variation is furnished by the Kiriri language,[76] which is also one of the numerous South American Indian forms of speech, where we find the words to be 5. mi biche misa = one hand. 10. mikriba misa sai = both hands. 20. mikriba misa idecho ibi sai = both hands together with the feet. Illustrations of this kind might be multiplied almost indefinitely; and it is well to note that they may be drawn from all parts of the world. South America is peculiarly rich in native numeral words of this kind; and, as the examples above cited show, it is the field to which one instinctively turns when this subject is under discussion. The Zamuco numerals are, among others, exceedingly interesting, giving us still a new variation in method. They are[77] 1. tsomara. 2. gar. 3. gadiok. 4. gahagani. 5. tsuena yimana-ite = ended 1 hand. 6. tsomara-hi = 1 on the other. 7. gari-hi = 2 on the other. 8. gadiog-ihi = 3 on the other. 9. gahagani-hi = 4 on the other. 10. tsuena yimana-die = ended both hands. 11. tsomara yiri-tie = 1 on the foot. 12. gar yiritie = 2 on the foot. 20. tsuena yiri-die = ended both feet. As is here indicated, the form of progression from 5 to 10, which we should expect to be "hand-1," or "hand-and-1," or some kindred expression, signifying that one hand had been completed, is simply "1 on the other." Again, the expressions for 11, 12, etc., are merely "1 on the foot," "2 on the foot," etc., while 20 is "both feet ended."
