Sutton's water-filled lens has been patented in England 28th Sept. 1859 (patent no. 2193). Two lenses with extremely concentric curvatures enclose a hollow space which had been filled with crystal clear water.

Quoted from Eder, "Die Photographischen Objektive", Halle 1911, p. 98. - The rarest lens in the history of optics.
