This Australian list might be greatly extended, but the scales selected may be taken as representative examples of Australian binary scales. Nearly all of them show a structure too clearly marked to require comment. In a few cases, however, the systems are to be regarded rather as showing a trace of binary structure, than as perfect examples of counting by twos. Examples of this nature are especially numerous in Curr's extensive list--the most complete collection of Australian vocabularies ever made. A few binary scales have been found in South America, but they show no important variation on the Australian systems cited above. The only ones I have been able to collect are the following: BAKAIRI.[188] 1. tokalole. 2. asage. 3. asage tokalo = 2-1. 4. asage asage = 2-2. ZAPARA.[189] 1. nuquaqui. 2. namisciniqui. 3. haimuckumarachi. 4. namisciniqui ckara maitacka = 2 + 2. 5. namisciniqui ckara maitacka nuquaqui = 2 pairs + 1. 6. haimuckumaracki ckaramsitacka = 3 pairs. APINAGES.[190] 1. pouchi. 2. at croudou. 3. at croudi-pshi = 2-1. 4. agontad-acroudo = 2-2. COTOXO.[191] 1. ihueto. 2. ize. 3. ize-te-hueto = 2-1. 4. ize-te-seze = 2-2. 5. ize-te-seze-hue = 2-2-1. MBAYI.[192] 1. uninitegui. 2. iniguata. 3. iniguata dugani = 2 over. 4. iniguata driniguata = 2-2. 5. oguidi = many. TAMA.[193] 1. teyo. 2. cayapa. 3. cho-teyo = 2 + 1. 4. cayapa-ria = 2 again. 5. cia-jente = hand. CURETU.[194] 1. tchudyu. 2. ap-adyu. 3. arayu. 4. apaedyai = 2 + 2. 5. tchumupa. If the existence of number systems like the above are to be accounted for simply on the ground of low civilization, one might reasonably expect to find ternary and and quaternary scales, as well as binary. Such scales actually exist, though not in such numbers as the binary. An example of the former is the Betoya scale,[195] which runs thus: 1. edoyoyoi. 2. edoi = another. 3. ibutu = beyond. 4. ibutu-edoyoyoi = beyond 1, or 3-1. 5. ru-mocoso = hand.
