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]

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]
