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. 21. (11.)—METHODS OF MAKING TAR—HOW CEDRIUM IS MADE.

In Europe, tar is extracted from the torch-tree2323 by the agency of fire; it is employed for coating ships and for many other useful purposes.2324 The wood of the tree is chopped2325 into small billets, and then put into a furnace, which is heated by fires lighted on every side. The first steam that exudes flows in the form of water into a reservoir made for its reception: in Syria this substance is known as “cedrium;”2326 and it possesses such remarkable strength, that in Egypt the bodies of the dead, after being steeped in it, are preserved from all corruption.2327
