a Ball 800 Paces; if one would know with the same Charge how many Paces it will shoot at the Elevation of 54 degrees.
See then, that at the said 54 degrees of the Ta∣ble corresponds the proportional Numb. 9511, and at the abovesaid Elevation of 458, or points of the Quadrant 6, corresponds the proportio∣nal Number 10000, which by the Golden Rule is so worked.
If 10000 gives me 800, so 9511 gives me the number of Paces which is required.
Thus I Multiply 9511 by 800, and Divide the Product by 10000, the Quotient will be 760, which are the Paces that the Mortar will shoot the Ball, with the Elevation of 54 degrees.
