About This Book

The work assembles systematic observations on animals, insects, and trees, combining natural history with practical notes. It surveys insect forms and habits, including bees, silk‑producing worms, spiders, and parasitic species, and discusses reproduction, classification, diseases, and useful products like honey and silk. It then examines animal anatomy in detail, limb by limb and organ by organ, comparing organs, vital functions, and bodily peculiarities across species. Later sections catalogue trees and exotic plants, describing aromatic gums, spices, frankincense, myrrh, and methods for producing and testing unguents and perfumes, and noting their uses and regions of origin.

CHAP. 83.—THE BLADDER: ANIMALS WHICH HAVE NO BLADDER.

Below the paunch, on the anterior side, lies the bladder, which is never found in any oviparous animal, with the exception of the tortoise, nor yet in any animal that has not lungs with blood, or in any one that is destitute of feet. Between it and the paunch are certain arteries, which extend to the pubes, and are known as the “ilia.” In the bladder of the wolf there is found a small stone, which is called “syrites;” and in the bladders of some persons calculi are sometimes found, which produce most excruciating pains; small hairs, like bristles, are also occasionally found in the bladder. This organ consists of a membrane, which, when once wounded, does not 304 cicatrize, just like those in which the brain and the heart are enveloped: there are many kinds of membranes, in fact.
