4. In process of time, names would be given to those collections of pebbles which are met with most frequently. But as long as small numbers only were required, the most convenient way of reckoning them would be by means of the fingers. Any person could make with his two hands the little calculations which would be necessary for his purposes, and would name all the different collections of the fingers. He would thus get words in his own language answering to one, two, three, four, five, six, seven, eight, nine, and ten. As his wants increased, he would find it necessary to give names to larger numbers; but here he would be stopped by the immense quantity of words which he must have, in order to express all the numbers which he would be obliged to make use of. He must, then, after giving a separate name to a few of the first numbers, manage to express all other numbers by means of those names. 5. I now shew how this has been done in our own language. The English names of numbers have been formed from the Saxon: and in the following table each number after ten is written down in one column, while another shews its connexion with those which have preceded it. One eleven ten and one[2] two twelve ten and two three thirteen ten and three four fourteen ten and four five fifteen ten and five six sixteen ten and six seven seventeen ten and seven eight eighteen ten and eight nine nineteen ten and nine ten twenty two tens twenty-one two tens and one fifty five tens twenty-two two tens and two sixty six tens &c. &c. &c. &c. seventy seven tens thirty three tens eighty eight tens &c. &c. ninety nine tens forty four tens a hundred ten tens &c. &c. a hundred and one ten tens and one &c. &c. a thousand ten hundreds ten thousand a hundred thousand a million ten hundred thousand or one thousand thousand ten millions a hundred millions &c. [2] It has been supposed that _eleven_ and _twelve_ are derived from the Saxon for _one left_ and _two left_ (meaning, after ten is removed); but there seems better reason to think that _leven_ is a word meaning ten, and connected with _decem_.
