Wilfred Thomason Grenfell, On Immortality, New York, The Pilgrim Press, 1912, p. 27.

If a disembodies spirit, or a  man from Mars, quite unacquainted with life as we live it on earth, were to find a mother with an unborn babe, he would certainly argue life for it in some other sphere from the texts of its purposeful limbs and organs. On the other hands, Mrs Gatty, in her exquisite Parables from nature, represents the caddis-worm under water as finding it hard to beleive that the chrysalis would ever fly free in an atmosphere then fatal to him.
