[July 



His observations were conducted on a more limited scale than those of 

 the officer last mentioned, and refer merely to appearances presented 

 on the way while proceeding with a detachment of troops on Military 

 duty. 



" The basalt and amygdaloid already described, continue during the 

 first part of the descent to the village of Parrah where they disappear, 

 soon after this red sandstone makes its appearance at Kaunass, felspar, 

 porphyry, flinty and mica slates mark the junction of the igneous and 

 sedimentary rocks, but in what position or quantity does not appear 

 from Captain Stewart's paper,* although in his figured representation 

 he makes the basalt and amygdaloid repose on sandstone, the reverse 

 of what obtains, according to Captain Dangerfield, on the northern 

 confines of Malwa. 



" From Parrah, the sandstone continues for half the way to Goorah, 

 the other half being composed of white quartz. Beneath the quartz a 

 l*ed of porphyry, composed as Captain Stewart thought, of large crys- 

 tals of quartz imbedded in felspar, and these ingredients, together with 

 the addition of a little mica, or in other cases hornblende, compose the 

 north-eastern frontier of the Guzerat, and even extend without inter- 

 ruption from thence to the AravuUy range, 300 miles north of the posi- 

 tion in M'hich they were first observed by Captain Stewart, forming, in 

 occasional conjunction with sandstone and quartz, the whole of the in- 

 termediate hills between the plains of Guzerat and the table lands of 

 Malwa, as well as the rugged mountains w'hich partially surround the 

 Pebur lake. 



" The plains which skirt the mountains on this side of ihe Guzerat 

 to the breadth of 50 or 60 miles, are composed of the peculiar granitic 

 rocks just mentioned, occasionally passing, according to Mr. Hardy, f 

 into granite, clay slate, and quartsiose sandstone. Insulated protrusion 

 of the same nature from the size of small hills to that of mountains, 

 rise abruptly from the surface of these plains, such as the fortress of 

 Champaneer, a conical elevation 2500 feet in height, and the insulated 

 mountain of Abu, the highest point of land in Central India, placed at 

 the western extremity of the AravuUy and Chittore ranges and from 

 which they, as well as the mountains on the eastern frontier of the 

 Guzerat, appear to radiate as from a centre. The plains of the Guzerat 

 for the breadth of forty miles along the coasts are formed of alluvium 

 Siimilar to that of the other plains of India.
