EXAM. 3.

In casting the contents of the casks given in this Example, let Sl. denote the Slide; B. I. the Brass Index on the Slide; St. the Stock; Sp. Spheroid; and G P. the Guage-Point on the Slide D. By this means we shall be able to abridge the method of expressing the operations of finding the mean diameters, contents and ullages.
