It is generally believed to have made its appearance during the later decline of the continental glaciers. It does not concern, however, the antiquity of the Black and Brown races, since there are numerous evidences of their existence in more southern regions, in times remotely pre-glacial.[1645]
As a specimen of geological certainty and agreement, these figures also may be added. Three authorities—Messrs. T. Belt, F.G.S., Robert Hunt, F.R.S., and J. Croll, F.R.S.,—in estimating the time that has elapsed since the Glacial epoch, give figures that vary to an almost incredible extent:
Belt: 20,000 years.
Hunt: 80,000 years
Croll: 240,000 years[1646]
No wonder that Mr. Pengelly confesses that:
It is at present and perhaps always will be impossible to reduce, even approximately, geological time into years or even into millenniums.
A wise word of advice from the Occultists to the gentlemen Geologists; they ought to imitate the cautious example of Masons. As chronology, they say, cannot measure the era of the creation, therefore, their “Antient and Primitive Rite” uses 000,000,000 as the nearest approach to reality.
The same uncertainty, contradictions and disagreement reign on all other subjects.
The scientific authorities on the Descent of Man are again, for all practical purposes, a delusion and a snare. There are many Anti-Darwinists in the British Association, and Natural Selection begins to lose ground. Though at one time the saviour, which seemed to rescue the learned theorists from a final intellectual collapse into the abyss of fruitless hypothesis, it begins to be distrusted. Even Mr. Huxley is showing signs of truancy, and thinks “natural selection not the sole factor”:
