CARDEW‚ Philip.	7597	Autograph Letter Signed‚ to Mr.trotter‚ making arrangements for their meeting. A good one page example‚ 7 x 4½ inches‚ Board of Trade‚ 10 July 1889. Major Philip Cardew‚ Royal Engineers (1851-1910)‚ inventor of the voltmeter‚ the vibratory transmitter for telegraphy‚ and other electrical devices. Cardew's invention of the vibratory transmitter for telegraphy was perhaps his most important‚ and in the case of faulty lines it proved useful not only on active service overseas but also during heavy snowstorms at home. He received a money reward for this from the imperial and Indian governments. The utility of the invention was greatly extended by his further invention of ‘separators’‚ consisting of a combination of choking coil and two condensers. These instruments enabled a vibrating telegraph circuit to be superimposed on an ordinary Morse circuit without interference between the two‚ thus doubling the message-carrying capability of the line. His apparatus for testing lightning conductors was adopted by the war department. [DNB]

Within months he had developed a new method of analysis for carbon and nitrogen content. His book‚ ‘Water Analysis for Sanitary Purposes’ was published in 1880. By more than three decades of work in water analysis he ensured much safer drinking-water for urban populations‚ thus helping to prevent a pandemic of water-borne disease. He was for many the leading British chemist of the nineteenth century.

He extended his researches on gaseous diffusion and he was able to make a clear distinction between effusion and transpiration (or viscous flow) of gases. In 1848 he began his liquid diffusion studies and found that there was no simple connection between diffusion speed and molecular weight for liquids. In 1852‚ faced with a wilderness of facts on osmosis‚ he coined the neologisms osmose‚ osmotic force‚ and osmometer. He explained that osmosis was liquid diffusion accompanied by osmose‚ or water‚ flowing in the opposite direction through a membrane. [DNB]
