Elephant supposed to live till 80; begins breeding at 20, ~~& has 6 young~~ — to simplify calculation a pair at end of every 20 years, so as to have 6 in whole life — then at end of 500 years from 1st Birth there wd be then alive, thus 5 million young — Falconer thought 20 too soon — & I shd think 90 wd be under average life.— In second paper the Elephant are supposed to produce 8 young & then the number is 15 &c millions.
