Abstract

Here I mean only what is meant by the word “twin crystals”, and not those regular intergrowths that are caused by mechanical shifts - a case already discussed in my previous works. It seems to me that the experiments of the regular overgrowths of heterogeneous crystals on each other and the conclusions drawn from them by F. Barker completely establish the physical cause of the formation of twins. The most general conclusion from the principle is that the possibility of twinning overgrowth along any plane of a complex, no matter how complex the symbol expressing it may be, for cases of twin faces with a complex symbol, is used in nature under exceptional circumstances.
