Bj an application of the principles set forth in section 1 more than250 dislocations have been mapped, and from the nature of things theremust be a large number of such dislocations which have not been dis-covered. As regards their direction, these faults fall into no fewer thaneleven series of parallel or nearly pai-allel dislocations, five-sixths of HOBBS.] MEASUREMENT OF STR
