I have hitherto only spoken of solutions of the vehicle and the disinfectant; such solutions are particularly applicable for long continued disinfections such as privies &c. where a uniform action is desired and the disinfection is more of a 5 prophylactic nature. In the case of epidemics, for the destruction of contageous elements, in medicine, or for the sick chamber, on the other hand, it is required to have an intensine action, though, may be, of short duration, yet as powerful as possible. In such cases there are employed with advantage emulsions of disinfectants lO soluble in water with one or more of the bodies serving as vehicle, with or without the use of bodies favoring emulsion, such as gum, glue, mucilage, soaps &c. These emulsions, when run on to liquids, spread with great rapidity over the surface, and at once decompose, the whole of the soluble disinfectants being rapidly and uniformly precipitated. • 15'* By this means a better mixture of the disinfectant with the body to be disinfected is attained than is possible with mechanical mixing devices. Disinfectants soluble in water more particularly applicable as emulsion- disinfectants are salts, soluble in water, of mercury, copper, iron, lead and zinc, also manganates, permanganates, arsenites, chlorates and perchlorates, chromates, 20* sulphites and hypochlorites, soluble in water, arsenious acid, salts of resin acid, fatty acids oxy-fatty acids, animal-fatty acids, soluble in water, also salts soluble in water of the aromatic carbon- oxycarbon- and tbio-carbon-acids, the phenolates and thio-phenolates soluble in water, as also the aqueous solutions of phenoles, in salt or soap solutions, and the aqueous quinine solution &c. 25 Lastly, a third form of floating disinfectant can be prepared by combining the before described solution and emulsion methods. Thus a disinfectant, partly dissolved in the vehicle and partly converted into an emulsion therewith is employed. The disinfectant which is soluble in the vehicle is for this purpose first dissolved therein, and this solution is then converted into an emulsion with the aqueous solution of 30 one or other of the above named soluble disinfectants. . -^ie acti°n of the substances at present known as disinfectants is considerably increased bj the covering action of the vehicle used in combination therewith ; the exclusion of the air greatly assists this action. Thus the disinfectant, plus the vehicle, have collectively a much more intense action than the sum of the separate 35> actions of each component. Dated this 11th day of January 1893. ABEL & I MR AY, Agents for the Applicant. COMPLETE SPECIFICATION. Improvements in Disinfectants. Dt go Noerdlinger, of Bockenheim, near Frankfort on Main, Germany, anufacturer, do hereby declare the nature of this invention and in what manner the same is to. be performed, to be particularly described and ascertained in and by the following statement:— J This invention does not relate to the production of a new disinfectant, but has for its object, to render existing disinfectants more efficacious in their action. It consists in mixing with disinfectants that are soluble in water, such as carbolic acid, a body that is not soluble in water and is specifically lighter than this, so as o oat upon it, such as a light tar-oil, so that the disinfectant in being dissolved in or held in suspension by such vehicle, when introduced into the effluent or other lqui to e disinfected, will float upon and be effectually spread over its surface. , The effective action of a disinfectant so mixed with an insoluble light vehicle, 40 45 50-
