"Know," saith John Swan, (Speculum Mundi 1643), "that the horn of a Unicome hath many sovereigne virtues, and with an admirable dexteritie expelleth poyson, insomuch that being put upon a table furnished with many junkets, and banqueting dishes, it will quickly decrie whether there be any poyson amongst them".

"In short (Night side of Nature, Catherine Crowe, as far back as in 1848), "we are the subjects, and so is every thing around us of all manner of subtle, and inexplicable influences; and if our ancestors attached too much importance to these ill understood arcana of the night side of nature, we have attached too little. The sympathetic effects of multitudes on each other, of the young sleeping with the old, of magnetism on plants, and animals, are now acknowledged facts. May not many other asserted phenomena that we yet laugh at, be facts also? though probably too capricious in their asserted nature, by which I mean depending on laws beyond our comprehension, to be very available? For, I take it, as there is no such thing as chance, all would be certainty if we knew the whole of the conditions".

To paraphrase a letter written by Sydney Smith, December, 1821, from Foston, for Lady Mary Bennett: "Dear Lady, spend all your fortune in an electric lighting apparatus! Better to eat dry bread by the splendour of electric light, than to dine on grouse by gas, or on wild beef with wax candles; and so, good-bye! dear lady".

To wear silken clothing next the skin, will serve to retain a healthful electrical state of the body, thereby promoting cheerfulness of mind under atmospheric surroundings which would otherwise depress.
