- The habitations of man in all ages of the world’s history
At first man built twig huts in trees, but becoming better matched with his animal foes he took to caves and underground habitations. Our illustration of the latter shows a section through the soil. Lake dwellings marked a distinct advance. Other varieties of primitive habitations are the leaf hut, the tents of skin, the mud hut, and the beehive hut of stone. Roman villas are still models of beauty. American “skyscrapers” are peculiar to our time; but all early forms of dwellings, while marking progress, have existed contemporaneously throughout history. - The first wanderers of the earth - Tribal migration in prehistoric times
From the painting of “Cain” by Ferdinand Cormon - Vivid scenes of ancient life depicted by contemporary artists
The walls of the tombs in Egypt form a great picture gallery of the vanished life of that country and are invaluable to the historian. This fragment from the British Museum shows how vividly the domestic figures were realised. - Ancient Egypt’s strange books and pictorial records, made of papyrus
Papyrus, a tall, graceful, sedgy plant, supplied the favourite writing material of the ancient world, and many priceless records of antiquity are preserved to us in papyri. The pith of the plant was pressed flat and thin and joined with others to form strips, on which records were written or painted. The above is a photograph of a piece of Egyptian papyrus, showing both hieroglyphics and picture-writing. The oldest piece of papyrus dates back to B.C. 3500. - The World as known to its first historian

- Egg-capsule of P. orientalis
A external view B opened C end view. The eggs of the Cockroach are laid sixteen together in a large horny capsule. This capsule is oval, with roundish ends, and has a longitudinal serrated ridge, which is uppermost while in position within the body of the female. The capsule is formed by the secretion of a “colleterial” gland, poured out upon the inner surface of a chamber (vulva) into which the oviducts lead. The secretion is at first fluid and white, but hardens and turns brown on exposure to the air. In this way a sort of mould of the vulva is formed, which is hollow, and opens forwards towards the outlet of the common oviduct. Eggs are now passed one by one into the capsule; and as it becomes full, its length is gradually increased by fresh additions, while the first-formed portion begins to protrude from the body of the female. When sixteen eggs have descended, the capsule is closed in front, and after an interval of seven or eight days, is dropped in a warm and sheltered crevice. In Periplaneta orientalis it measures about ·45 in. by ·25 in. - Longitudinal section of Female Cockroach

Salted Cockroaches are said to have an agreeable flavour which is apparent in certain popular sauces. - Tumbling
