- And though it might be thought that all animals who have lungs do cough; yet in cataceous fishes, who have large and strong lungs, the same is not observed; nor yet in oviparous quadrupeds: and in the greatest thereof, the crocodile, although we read much of their tears, we find nothing of that motion.
