12 and 13 are the transverse and longitudinal sections of a common form of American marine boiler.

Only 12 of them were soldiers, of whom 7 have since died.

It is probable that 12 per cent, is not an excessive figure to take as the representative of the average proportion of unemployed.

12 are two rods, one vertical and the other inclined.

The number produced at each litter depends upon the character of the breed; 12 being the average number in the small variety, and 10 in the large; in the mixed breeds, however, the average is between 10 and 15, and in some instances has reached as many as 20.

A 2, 3, or 12 was a "no pass."

Again, I have power to change the factors and write 4 X 3, in which case 12 is the only possible result, and so on.
