it has been calculated, to account for the last submergence of the northern hemisphere during the Champlain Epoch. The submergence of the southern polar lands is now in progress. Should the connection of "the glacial period”—and of other glacial periods more ancient-with cosmical conditions, be satisfactorily established, it seems to me that we are here furnished with a hopeful means of giving greater precision to the calculus of geological time. For detailed information on these questions, see Croll, Philosophical Magazine for August, 1864, and February, 1867; Transactions Geol. Soc., Glasgow, April, 1867; Revue des deux Mondes, 1847, etc. NOTE VIII., page 287. As the records of the flowing wells of oil springs constitute one of the most remarkable chapters of the history of Petroleum, I append here a list of them, made from personal examination and research. In this list, “Sub.” stands for subdivision, "R." for range, "L." for lot, and “Con.” for concession.

The thoughts embodied in this and the five following chapters were first shadowed forth by the author in the Michigan Journal of Education in 1860. They were more fully elaborated in the Ladies' Repository for November and December, 1863, and January, 1864. Many thoughts and conceptions which were then original appear to be now but the echoes of Mayer, Helmholtz, and others. This is particularly the case in reference to the doctrine of solar refrigeration. That doctrine, then entirely new to the writer, was put forth with much apprehension. The publication of Mayer's papers in Silliman's Journal (vol. xxxvi., p. 261; xxxvii., p. 187; xxxviii., p. 239, 397) in 1863 and 1864 afforded the writer the first exact basis for conclusions which he had already reached. The later researches of others have served to give a scientific sanction to statements which at one time might have been regarded as little more than vagaries of the imagination. NOTE X.; page 404. Such, at least, is the generalization put forth by Müncke, Mrs. Somerville, and other physicists. It is apparently founded on reports of observations made by Scoresby and Parry in the Arctic Ocean, and by James Ross in the Antarctic. M. Charles Martins, however, a highly competent authority, denies that any such increase of temperature in the deeper arctic waters exists. Nothing of the kind was observed by le Contre-Amiral Coupvent des Bois in the voyage of the corvettes Astrolabe and Zélée; nor in the soundings made on the two voyages to Spitzbergen with the corvette Recherche.
