Prof. Oscar Paschel, in his work on "Mankind," speaking of the deposits of human remains which have been discovered in caves, mingled with the bones of wild animals, says: "The examination of one of these caves at Brixham, by a geologist as trustworthy as Dr. Falconer, convinced the specialists of Great Britain, as early as 1858, that man was a contemporary of the Mammoth, the Woolly Rhinoceros, the Cave-lion, the Cave-hyena, the Cave-bear, _and therefore of the Mammalia of the Geological period antecedent to our own_."[30:2] The positive evidence of man's existence during the _Tertiary_ period, are facts which must firmly convince every one--who is willing to be convinced--of _the great antiquity of man_. We might multiply our authorities, but deem it unnecessary. The observation of shells, corals, and other remains of _aquatic animals_, in places above the level of the sea, and even on high mountains, may have given rise to legends of a great flood. Fossils found imbedded in high ground have been appealed to, both in ancient and modern times, both by savage and civilized man, as evidence in support of their traditions of a flood; and, moreover, the argument, apparently unconnected with any tradition, is to be found, that because there are marine fossils in places away from the sea, _therefore the sea must once have been there_. It is only quite recently that the presence of fossil shells, &c., on high mountains, has been abandoned as evidence of the Noachic flood. Mr. Tylor tells us that in the ninth edition of "Horne's Introduction to the Scriptures," published in 1846, the evidence of fossils _is confidently held to prove_ the universality of the Deluge; _but the argument disappears from the next edition, published ten years later_.[30:3] Besides fossil remains of aquatic animals, _boats_ have been found on tops of mountains.[30:4] A discovery of this kind may have given rise to the story of an _ark_ having been made in which to preserve the favored ones from the waters, and of its landing on a mountain.[30:5] Before closing this chapter, it may be well to notice a striking incident in the legend we have been treating, _i. e._, the frequent occurrence of the number _seven_ in the narrative. For instance: the Lord commands Noah to take into the ark clean beasts by _sevens_, and fowls also by _sevens_, and tells him that in _seven_ days he will cause it to rain upon the earth. We are also told that the ark rested in the _seventh_ month, and the _seven_teenth day of the month, upon the mountains of Ararat. After sending the dove out of the ark the first time, Noah waited _seven_ days before sending it out again. After sending the dove out the second time, "he stayed yet another _seven_ days" ere he again sent forth the dove. _This coincidence arises from the mystic power attached to the number seven, derived from its frequent occurrence in astrology._
