It is much to be desired that the central portions of the Tîh should be traversed in several directions by competent geologists. From the notes recorded by Mr. Milne and the Rev. F. W. Holland it may be inferred that there is more variety in the stratification of that region than is generally supposed; and that a somewhat detailed reconnaissance would bear interesting results.
