No fact in Physical Geology is more frequently recorded than a simultaneous occurrence of subsidence of the earth’s crust where deposition of sedimentary strata has been in progress. Reference is often made to the fact that the basement beds of different sedimentary formations were deposited in shallow water, and to the indications presented by subsequent deposits that they were accumulated in a sea of moderate depth. On them immense accumulations may have been deposited in successive strata, amounting even to miles in thickness; showing that with the deposition there has been a corresponding depression of the original surface. Though these phenomena are so inseparable in their occurrence and so well known, English geologists, until the last few months, have made little, it may even be said no endeavour, to determine whether they should be associated as cause and effect. This has not been the case with American geologists.
page 302 note 1 The following are Croll’s words: “Prof. Hseckel may male any assumption he chooses about the age of the sun, but he must not do so in regard to the sun's heat. One who believes it inconceivable that matter can be created or annihilated may be allowed to maintain that the sun existed from all eternity, but he cannot be permitted to assume that our luminary has been losing heat from all eternity. “—Nature “ for Jan.10, 1878.

page 304 note 3 Physics of the Earth's Crust by the Rev. Osmond Fisher, M.A., F.G.S., p. 83. Referring to the Himalayan region, it was stated by myself in 1875, when replying to objections which had been raised, that the removal by denudation of those portions of the mass which once filled up the spaces now forming the valleys and passes of this great mountain range, must have diminished proportionately the amount of weight pressing upon the fluid substratum Should the sediment brought thence by the Ganges and Brahmapootra, and deposited in the Bay of Bengal, cause subsidence by its weight, it follows that the area from which the sediment has been derived must rise in proportion to the amount of material removed.—The Cause of the Glacial Period, by Charles Ricketts, Geol.
