We must, however, observe that in the eleven different numbers which may be thrown with two dice, 7, which is the mean proportional between 2 and 12, has more chances than the others, which on their side have more or less chances in their favour as they ap­proach the two extremes. This difference of the multitude of chances pro­duced by the mean numbers compared to the ex­treme, increases considerably in ratio to the num­ber of dice. It is such, that if we make use of seven dice, which produce points from 7 up to 42, we shall find that we shall almost invariably throw the mean numbers 24 and 25, or those which ap­proach the nearest to them, viz. 22, 23, 26, 27 ; and if, instead of seven dice, we make use of twenty-five, which will produce numbers from 25 to 150; we might with safety bet an equal wager to throw 86 and 87- The above remaik is important, as it must tend to expose at a glance the gross imposition of those
