Job 41:20

Out of his nostrils goeth forth smoke, as out of a seething pot or caldron. In which flesh or anything else is boiling. It is observed that there is a likeness between the crocodile and the river horse, and particularly in their breathing F21 Plin. l. 48. c. 8. Aristot. Hist. Animal. l. 8. c. 2. : and of the former it is remarked F23 Achilles Statius & Eustathius, apud Scheuchzer: ut supra. (vol. 4. p. 849.) , that its nostrils are very large and open, and that they breathe out a fiery smoke, as out of a furnace.
