On the whole there seems little doubt that successful crystalgazing is the exertion of a not uncommon though far from universal faculty, like those of "chromatic audition" - the vivid association of certain sounds with certain colours - and the mental seeing of figures arranged in coloured diagrams (Galton, Inquiry into Human Faculty, pp. 114-154).

A system is said to be " chromatically under-corrected " when it shows the same kind of chromatic error as a thin positive lens, otherwise it is said to be " over-corrected."
These, however, since they share the general lengthening or shortening of wave-length through motion, are thereby shifted, to a certain definite extent, into visibility, and so produce accurate chromatic compensation.
With this mineral also spherical and chromatic aberration are a fraction of that of a glass lens, but double refraction, which involves a doubling of the image, is fatal to its use.
When well made such constructions are almost free from spherical aberration, and the chromatic errors are very small.
