The writer determined experimentally the twinning plane of zinc crystal as (101^^-2) plane, firstly observing the twin lamellae on the three crystallographical planes such as basal, prismatic and diagonal planes. Nextly for the purpose of testifying the twinning rule, the writer graphically calculated the directions of secondary twin lamellae which must occur in primary twin lamellae on each plane, based uppon the same role that the twin occurs along the twinning plane (101^^-2). The graphically calculated results were identical to observed values of secondary twins. Supplement : Conditions for Product of Large Single Crystal of Zinc by Strain Method. The peculiar point of condition for product of large single crystal of Zinc by strain method differing from other ductile materials as copper, iron and aluminum etc., is on the limiting strain. The strain should be as severe as possible. The straining method and annealing temperature and duration are given in this supplementary papar.
