For this reason the physical science of crystallography has developed side by side with that of mineralogy.
crystallography, however, did not absorb all Hay's attention.
Now in crystallography there are only thirty-two possible classes of crystal lattice construction.
There has been nothing peculiar, however, in the growth of crystallography.
He was still trying to read a little chemistry and crystallography, but it didn't "go with the life."
He introduced a new classification of minerals, based on crystallography.
In short, in crystallography we have another example of perfect practical mathematics, as perfect as the theory.
This was especially exemplified in the case of the Abb Hay, whose work in crystallography was to mean so much.
The animal was classified very nearly after the manner adopted in crystallography.
The study of the geometric forms assumed by minerals (crystallography) forms a department of the science of mineralogy.
