That in the said Number, for want of Marks proper to express Multiplication, there was used, pag. 571. l. 5, 7. the mark of Plus or Addition, which yet 'tis thought could hardly occasion any mistake in the intelligent Readers, who might easily see the meaning of the Author by the lines 8, 9, 10. of the next precedent page 570.
