Water, ether insol.1.2 0.3 Silver salts 9.5 6.5 Raw picric acid 0.6 0.2 the silver chloride was concentrated to a very small volume, extracted with ether and the ether solution brought to dryness. The partly crystallized residue was dissolved in 20 cc. of coned, hydriodic acid and the solution kept in a sealed tube for six hours at 170-180°. On cooling the solution became turbid.
