The instances I have cited may now be summed Kaliana rock shows (?) interlocking structure of quartzwith removal of matrix ; the Charli rock shows cavities withpossible interlocked structure of matrix. The rocks describedby Mr. Card show cavities with possible interlocking of mainmaterial of rock (dolomite). It would appear from these results that interlocking is oftendoubtful, and in the main subsidiary ; that flexibility dependson (1) the nature of the matrix ; (2) the removal of suchmatrix in suitable proportion, as set forth by Mr. Oldham,so as to allow of free movement of the other constituents ofthe SIR JAMES AGNEW, , , (^bxiixavu.
