To explain, I will exhibit the heads of Seneca's and Cicero's philosophical works, the most extensive of any we have received from the ancients. Of ten heads in Seneca, seven relate to ourselves, viz. de ira, consolatio, de tranquilitate, de constantia sapientis, de otio sapientis, de vita beata, de brevitate vitae; two relate to others, de elementia, de beneficiis; and one relates to the government of the world, de providentia. Of eleven tracts of Cicero, five respect ourselves, viz. de finibus, Tusculana, academica, paradoxa, de Senectute; one, de officiis, relates partly to ourselves, partly to others; one, de amicitia, relates to others; and four are on different subjects, to wit, de natura deorum, de divinatione, de fato, and somnium Scipionis.

These ordinates are arithmetical progressionals, each of which is double the root of its abscissa, plus unit. The equation, therefore, expressing the law of the curve is y = 2 N x + 1; that is, the velocity of the water of any depth will be double the root of that depth, plus unit. Were the line a e a wall, and b f e g d h e i troughs, along which water spouted from apertures at b c d e, their intersections with the curve at f g h i would mark the point in each trough to which the water would flow in a second of time, abating for friction.
