(19) Mr. Southall, in "Recent Origin of Man," p. 475, quotes,
from Dr. Andrews, of Chicago, to the effect that these
calculations are very erroneous, as he thinks that M. Morlot
forgot that the size of the cone would increase more and more
slowly. On the contrary, M. Morlot says as follows: "Only this
growth must have gone on at a gradually diminishing rate,
because the volume of a cone increases as the cube of its
radius. Taking this fact into consideration, etc." (Smithsonian
Report, 1860, p. 341.) There are, however, several objections to
this calculation, for which see Lubbock's "Prehistoric Times,"
p. 400; also Quatrefages's "Human Species," p. 138.

this calculation see Southall's "Recent Origin of Man."
