GOLDACRE1 has shown that if a surface film of a lipo-protein on water is compressed, it tends to form folds and ultimately cigar-shaped fibres consisting of a double lipo-protein layer with water inside and outside. It was suggested that such fibres could have been a reaction-space for the original formation of living cells. Danielli2 formed double lipo-protein layers by dropping dense protein solution through an oil layer into a less-dense protein solution. In this case, the film was spherical in shape and included a layer of oil. Sigwart and Nassenstein3have formed spherical shells of water in benzene by ejecting benzene drops from a nozzle preferentially wetted by water.
