"The Student's Elements of Geology"
Sir Charles Lyell
To him, the old definition that an animal is possessed of life and locomotion, a plant of life without locomotion, and a mineral deficient in both, seems to be sufficient, until some day he travels beyond the circuit of diurnal routine, and encounters a sponge or a zoophyte, which possesses only one of his supposed attributes of animal life, but which he is assured is nevertheless a member of the animal kingdom.
"Fungi: Their Nature and Uses"
Mordecai Cubitt Cooke
