Some years ago I described a doubly refracting structure in silica glass. This was detected by examining the glass between crossed nicols, using the necessary precautions to get a really dark field, so that very weak double refractions are brought into evidence. The character of this double refraction was such that it could not be attributed to mechanical stress, and had rather to be assimilated to the “liquid crystals” observed by Lehmann in some melted organic substances.
