"Research carried on since 1925 has shown that the formation and arrangement of crystals during the process of crystallization can, under certain conditions, be greatly influenced by the admixture of various substances.... Hence, from these alterations (in form) apriori conclusions can be drawn about the qualities and characteristics of the admixture itself."This is an essential element in his work of analyzing the health and qualities of human blood as an aid in the process of diagnoses.
