D'A. Bernard, it is especially important, in the dry distillation of distiller's wash in a closed vessel, for the production of methyls, ammonia, acetates, and methylamine, that the mass shall be divided as completely as possible, since it then takes but a relatively moderate heat to completely destroy the organic coloring matter contained in the wash.
The action of strong hydrocholoric acid upon morphine changes it into apomorphine, C H NO , by the withdrawal of a molecule of water. Ferricyanide of potassium and caustic soda solution change morphine into oxidimorphine, C H N O . When heated with strong potassium hydrate, it yields methylamine. In this case, instead of opianic acid, its reduction product meconine, C H O , is produced.
The gases disengaged during the operation pass into a cooler, where they condense into a liquid which contains ammonia and methylamine. The non-condensable part of the gases is burned in the furnace of the manufactory. In the American Court of the Inventions Exhibition, London, we find a leveling machine for sheet metals exhibited by Mr. J.W. Britton, of Cleveland, Ohio, and which we illustrate.
