To quickly assess the difficulty of the text, read a short excerpt:
Tyrotoxicon has been obtained in poisonous cheese (Vaughan, Wallace, Wolff), in poisonous ice-cream (Vaughan, Novy, Schearer, Ladd), in poisonous milk (Vaughan, Novy, Newton, Wallace, Firth, Schearer), and in cream-puflfs (Stanton). The methods of separating this poison and its eifect upon animals have already been given with sufficient detail. Chemically, it is very instable. When warmed with water to about 90°, it decomposes. Hydrogen sulphide also decomposes it, there- fore all attempts to i...solate it by precipitation with some base, such as mercury or lead, and then removing the base with hydrogen sulphide, have failed. Its unstable char- acter is illustrated by the fact that it may disappear altogether within twenty-four hours from milk rich in the poison which is allowed to stand in an open beaker. With potassium hydrate it forms a compound which agrees in crystalline form, chemical reactions, and the per cent, of potassium which it contains, with the compound of diazobenzole and potassium hydrate.
