 A point in the above notes to which special attention is 

 directed is the occurrence on the sandstone escarpments, far 

 above any limestone or limestone drift, of plants usually 

 strongly calcicole. SesUria, as noted, is abundant in such 

 situations ; and with it occasionally are Arabis hirsuta and 

 Asplenium Ruta-muraria. These grow mixed with typical 

 calcifuge species, such as Vaccinitim Vitis-Idcea, V. Myrtillus, 

 Callu7ia^ Erica, Digitalis, and Blechmim.

 my best thanks are due for assistance with critical plants.
