Fósforo em Steiner (2007)

There is a very good friend of the farmer — the field-mouse. What do they not try to do to fight against it! Read of it in the agricultural text-books. To begin with, all manner of phosphorus preparations were used; then, other things, such as the “Strychnine-Saccharine” preparations. Nay, an even more radical method has been proposed, namely, to infect the field-mice with typhus. Certain bacilli, harmful only to rodents, are added to mashed potatoes and the bait is distributed. Such things have also been done — at least, they have been recommended. (Steiner 2007:54)
