William Boyd Dawkins,
Cave Hunting
“ The layers, for instance, in Kent’s Hole, which are generally believed to have demanded a considerable lapse of time, may possibly have been formed at the rate of a quarter of an inch per annum, and the human bones which lie buried under the stalagmite in the cave of Bruniquel, are not for that reason to be taken to be of vast antiquity. It may be fairly concluded, that the thickness of layers of stalagmite cannot be used as an argument in support of the remote age of the strata41 below. At the rate of a quarter of an inch per annum, twenty feet of stalagmite might be formed in 1,000 years. ”
