The data of the science were rendered manageable ; and when its funda mental ideas were revised it was happily found that not demolition and reconstruction of the science, but rather adaptation, re-facing and extension were involved. It is nothing new in the history of thought that a study founded on false hypotheses should embody a framework of permanent value. Physics so frequently alters its hypotheses that physi cists themselves may be left behind. But on each occasion the science of physics does not collapse ; on the contrary little has to be sacrificed; and in its unchecked building up "we are presented with the spectacle of scholars working on different hypotheses, but
