Unprecedented Historical Documentation of Colloidal "Collosols" Silver Scientific American, Volume 78, Page 2 & 3 - 1914
Scientific American Supplement No. 2009 - July 4, 1914 On Metallic Colloids and Their Bactericidal Properties* The History of Collosols - By Henry Crookes *Paper read before the Royal Society of Medicine, April 8th, 1914, and published in the Chemical News Par. 1 "How many angels can stand on the point of a needle" Par. 4 "About that time (1903), or shortly afterward, the attention of medical men was directed in a critical scientific manner, apart from tradition and empiricism , to the curative effect of certain waters from mineral springs. Laborious research on the part of many workers has revealed the fact that these curative waters contain extremely small metallic particles, endowed with continuous, rapid, oscillatory movement known as the "Brownian movement."" Par. 5 "One method, known as Bredig's method, of effecting this result was by using a high-tension disruptive electric spark under water, between poles of the metal to be dealt with. Solutions containing an almost incredible number of particles of metal were prepared by these means, and it was soon found that these liquids had a very high germicidal power." Par. 11 "I know of no microbe that is not killed in laboratory experiments in six minutes." ..I will prepare this article in its entirety, in a digital format (hopefully within a week) for those interested in reading it. ~Ron N
