I $4 VREDENBURG : SKETCH OF BALCCHISTAN DESERT. 



Persian province of Sarha'd. Major Brazier-Creagh collected, 

 amongst the recent volcanoes, a very interesting series of specimens 

 which were examined at the Office of the Geological Survey of India 

 and described in the Records. 1 An acco int of the journey is given 

 by Colonel Sykes in his u Recent Journeys in Persia". 2 



Our geographical knowledge of these regions was completed by 

 the Afgha'n-Baluch boundary commission of 1894-96, and the Perso- 

 Baluch boundary commission of 1890^ 



I travelled through several of the localities visited by the members 

 of these commissions, which has enabled me to complete some of 

 the geological data connected with the mode of occurrence of the 

 specimens which they collected. The route followed by the Afgha'n- 

 Baluch boundary commission in 1896 coincided in several places 

 with my own line of march ; and in that year, two series of speci- 

 mens were collected respectively by Dr. F. P. Maynard and Captain 

 _ „ , n . A. H. McMahon. The former collection was

the Asiatic Society of Bengal in December 1896, and published in 



the Records of the Geological Survey of India. 4
