My attention has been drawn to a recent notice' by Mr. Colesof a quartzite at Martley. Since this area is included withinthe district of the Malvern and Abberley Hills, which I have beenengaged in studying for more than two years, a brief descriptionof the relations of the rocks, as determined by myself in Januaryof the present year, may not be out of place. The small patch of interesting rocks here is likely to become covered up as cultivation progresses; indeed, the exposure is evidently much less extensive than it was when Phillips described it in his memoir on the Malvern and Abberley Hills. Mr. Coles has, moreover, I think, hardly done justice to the remarkable section exposed here.
