Names of persons having employed their attention for giving the common water the most efficacious extinguishing property, for the purpose of subduing fire :
1734. M. Fuches, a German Physician, by throwing Balls into the fire, containing certain preparations which burst with violence, instantly quenched the Alaine.
1761. Zachary Grey used the same process, in which were allum, sal ammoniac, and other saline matters, with water.
In the same year Dr. Godfrey, in & public exhibition in a house erected for that purpose near Mary-le-bone, applied the like ingredients with great success, by the action of confined gunpowder only, which exploding dispersed the solution on the materials in combustion, and effectively extinguished the same.
1792. M. Von Ahen, at Stockholm, made numerous public experiments, to show the effects of several combined ingredients to render materials entirely incombustible ; he is stated to have subdued an artificial fire by 2 men and 40 measures of preparation that would have required 20 men and 1500 of the same measures of simple water.
In the same year, M. Nil Mosheio made many public exhibitions, to confirm that combustible materials might be made perfectly incombustible; as also did Mr. W. Knox, of Gottenburg
