It is not soluble in cold water,and has no taste; but it is soluble in alco-hol, and the solution has a bitter best solvent is chloroform, four and ahalf parts of which dissolve one part. Itmelts at a high temperature, and sublimesin white crystals a few degrees above itsmelting-point. Nitric, iodic, and sulphuricacids have no action on it. Sulphomolyb-dic acid produces a pale reddish-browncolor. Bichromate of potash added to the mixture with sulphuric acid produces no colors like strychnia, but onlygreen oxide of Crystals of sautouin, magnified llidiameters. BEARDED DARNEL (LOLIUM TEMTJLENTUM). Symptoms and Effects.—Poisoning by darnel is generally the resultof accident from the admixture of the seeds of this grass with wheat orrye. The seeds are ground into flour and eaten with the bread. Fromexperiments on animals, and from a few observations on man, it ap-pears that the seeds of darnel, whether taken in powder or in decoction,have a local action on the alimentary canal, and a remote action on thebrain and nervous system. There is heat, with pain in the stomach,accompanied by nausea, vomiting, and diarrhoea. These symptoms arefollowed by languor, loss of vision, ringing in the ears, and order to produce such serious effects, the poisonous grain must betaken in a somewhat large dose.
