“Many creatures go through a natural change and by decay pass into different forms, as bees [are formed] by the decaying flesh of calves, as beetles from horses, locusts from mules, scorpions from crabs.”
Bk. 11, ch. 4, sect. 3; p. 221.

Siquidem et per naturam pleraque mutationem recipiunt, et corrupta in diversas species transformantur; sicut de vitulorum carnibus putridis apes, sicut de equis scarabei, de mulis locustae, de cancris scorpiones.

“A living thing
Produced too slowly ever to decay;
Of form and aspect too magnificent
To be destroyed.”
Yew-Trees, l. 9 (1803).
Context: Of vast circumference and gloom profound,
This solitary Tree! A living thing
Produced too slowly ever to decay;
Of form and aspect too magnificent
To be destroyed.
