 | | It has an acid reaction, is soluble in ether, benzol, volatile oils, partly soluble in aqueous alkalies, soluble in strong sulphuric acid with a red color, and has a peculiar odor and somewhat acrid taste. |
 | | The alcoholic extract insoluble in dilute sulphuric acid, was entirely soluble in dilute ammonic hydrate and reprecipitated by an acid; it was flish brown, brittle, opaque, inodorous and tasteless, and in concentrated alcoholic solution had an acid reaction. |
 | | The precipitates obtained with the benzol and with the alcohol extract by potassio-mercuric iodide were separately treated with stannous chloride and potassa; on exhausting with ether and evaporating, minute apparently crystalline residues were obtained which were not further examined. |
