Cowan reports that Swedish peasants had Decticus verrucivorus, a kind of grasshopper, bite warts on their hands. They believed the black fluid it released from its mouth would make the warts disappear. This was a folk remedy he recorded, not a tested or recommended treatment^[1]. He also says boys attributed wart-curing power to similar black fluid from grasshoppers, which they called “tobacco spit”^[2].

In the traveller’s account recorded by A Hundred Anecdotes of Animals, the orangutan reportedly wedged a stone into an open oyster shell so it could not close on its paw, then drew out the oyster and ate it^[1].

During cereal grain germination, such as in corn or wheat, a coordinated handoff takes place between the starchy endosperm and the embryo to supply necessary nutrition ^[1][2].

The starchy endosperm acts as a storage tissue that surrounds the embryo and holds reserves primarily in the form of starch ^[3]. Rather than simply sitting beside the embryo as passive food, these reserves must be actively mobilized ^[4]. This is where specialized tissues come into play:

• Aleurone layer: This outer layer of endosperm cells remains alive and secretes hydrolytic enzymes, such as amylase, which digest the endosperm's stored starches into usable sugars ^[5][6].
• Scutellum: Acting as a nutrient transfer link between the embryo and the endosperm, the scutellum absorbs the newly released sugars and nutrients and passes them directly to the embryo ^[7].

This biochemical pipeline creates a dynamic transfer pathway rather than a simple static food source ^[8][9]. By converting complex stored reserves into accessible energy and nutrients, this mechanism directly supports early seedling growth ^[10].

In The World of Wonders, the Great Eastern is a ship of almost startling scale: 680 feet long, 83 feet broad and 58 feet deep, with a reported tonnage of 23,000 tons. Each paddle-wheel measured 58 feet across. The book says each of the four engine cylinders was cast in one piece, weighed 28 tons and had a 14-foot stroke; the condenser was another single casting of 36 tons^[1].

The book dates the start of Brunel’s work to 1854, describes the ship as constructed at Millwall in 1857, and says nearly a million pounds had been spent before she was tried. Financial difficulties brought a new company in 1858. She went to sea in autumn 1859, when a destructive accident occurred off Hastings^[2]. In the book’s account of the casualties that followed, she endured an Atlantic hurricane that damaged her paddles and disabled her rudder, then struck a rock at New York, breaking bottom-plates along 80 feet of her hull. Those plates, it says, were repaired while she remained afloat^[3].
