SEC. 9.] COUNTRY WEST OF DHENODUU. 219 



and a half to the south of Burra Malka, resting upon a thick bed 

 of amygdaloidal concretionary trap, with an irregular upper surface. 

 The junction with the next flows above does not appear in the sketch, 

 but they occur of the usual basaltic character at a short distance in such 

 a position as to overlie the thick sandstone bed. 



Further to the south-east in the steep northern face of the spur, 

 which extends nearly to Guranee, this bed was again met with, though 

 apparently nearer to the local base of the traps, where the following 

 succession was noticed :—

The alteration caused by the lowest trap No. 5 is very slight, and 

 only traceable for about 8 inches downwards.
