Ix. of the hydrostatic pressure of the oceans must also be taken account of. _ For suppose that any portion of the curve be covered by a heavy fluid (the ocean) of density p. Let c be the height of this ocean above the level, upon which the origin was taken in the first instance (on p.101). Then, in forming the equations of equilibrium, we shall have as before t= gpk (U —y). But for p we shall have, p= pressure at A+ pressure due to the depth below A — pressure due to the ocean, = go (h —y) + gp5— gp (c—y), =-—g9(o—p) y+ (oh — pc) + gpd. This is an equation of the same form as before. We cannot find the values of the constants exactly as we did before, but we can see that the curve must consist of two portions, one above the ocean and one below it. At the point where these two portions meet one another, the direction of the curve must be continuous. The portion above this point will evidently follow the law already investi- gated in all respects. For the part below we have expressions for p and ¢ of the same form as before. This part will, there- fore, follow the law of a curve, which may be supposed to rest upon a liquid of the density o — m instead of o. The law of form will, therefore, be the same as before, the constants being determined according to this supposititious case. The compression (t) of the part of the curve beneath the ocean will, however, be greater than in the supposititious case, the crest being higher. But that will not alter its form, be- cause (f) in any case varies according to the height of the anti- clinal. The radius of the portion beneath the ocean will be ae o — pb The diagram illustrates-the effect of increased general com- pression in elevating and depressing points in the crust. The COMIC OOOKS.EO
