(To face page 98.) Fig. 2. DISCUSSION AND SIGNIFICATION OF RESULTS. 99 From this approximate agreement as to the times between theory and observa-tion one might be led to infer that the unknown polar region consists entirely of adeep ocean (Nansens hypothesis). But, as already noted, deep channels of watersurroundmg land, islands, or shoals would have nearly the same equilibrium tide asa deep basin having the same outer boundaries, and here only have tidal observa-tions been made. In other words, a nucleus of land does not affect the equilibriumtides in any sufficiently deep body of water, unless the center of gravity of the waterssurface be displaced because of this land. The diurnal tides at Port Virgo, Treurenberg, and Mossel Bay are closely relatedto those at Vardo, Fineide, Kabelvaag, Bodo, and Bergen on the coast of Norway, asthe values of K^ —0^° and OJK^ establish beyond all reasonable doubt.
