    To go on with our Art; ’tis further to be ob¬ serv’d, that z and y being made ufe of to reprefent the Cypher, where many Cyphers meet together, as in 1000, 1000000, &c. inftead of a Repetition of azyzyzy, which could neither be eafily pro¬ nounced nor remember’d ; let g Hand for Hundred, th for Thoufand, and m for Million. Thus ag will be 100, ig 300, oug 900, &c. ath 1000, cth 4000, otho or othf 4004, peg 7200, dig 2300, lath 51000, am 1000000, azmoth 10.004,000, Junius 65000056, loum 59.000,000, &c. The folid Con¬ tent of the Earth is two Hundred fixty four Thou¬ fand, eight Hundred fifty fix Millions of Cubicle Miles; this is exprefs’d by the Word Solconter- efo-klaum ; Solconter (landing for the so Lid coNtent of the Earth ; efo~klaum for 264,856.000,000 the Number of Cubick Miles. It will be fometimes alfo of ufe to be able to fet down a Fradion, which may be done in the fol¬ lowing Manner : Let r be the Separatrix between the Numerator and the Denominator, the firft co¬ ming before, the other after it; as iro J- urp J pwrag ^ or ,79 northor ,094 &c. 4 Where the Numerator is 1, or Unit, it need not be expref- fed, but begin the Fradion with r, as ~ re, - riy ro, &c. So in Decimals, ,01 or ~, rag, ',001 crT^rr rath. Thus I have given the Reader a general View of what is the principal Part of this new Method. I fhall now proceed to (hew how I have applied it to Hiftory, Geography, Aftronomy, and other Parts of ufeful Learning ; and having explain’d a Line or two in each, leave the reft to his own In- duftry and Sagacity.
