in irregular masses in the serpentine, and is quarried out and sent 

 down to the coast on camels, with no further treatment at the 

 mines than a rough picking by hand. 



In a cutting, made for draining the water from a quarry visited 

 by the author, the accompanying section was seen : —

Besides the chromite-deposits above mentioned, the district is 

 also remarkable for the occurrence of two other not very common 

 minerals, namely meerschaum and boracite ; the former is mined on 

 a large scale near the town of Eski Chehir, and the latter near 

 Bali Kessir. 



With regard to the distances, which have been stated in time, it 

 may be mentioned that this is the usual way of reckoning distances in 

 Anatolia. Naturally the number of miles travelled per hour varies 

 with the condition of the 'road' and the more or less mountainous 

 character of the country. In this journey, which was chiefly 

 among mountains, the average distance covered per hour was 

 probably only 3 miles. 



The author would recommend the student of the geology of 

 Western Asia Minor to consult the paper on this subject by Messrs. 

 Hamilton and Strickland, Trans. Geol. Soc. ser. 2, vol. vi. pt. i. 

 (1841) p. 1. In it will be found much valuable information 

 regarding the age of the rock-formations. The origin of the Ter- 

 tiary lacustrine deposits, over three of which the author passed, as 

 shown in fig. 1, is there discussed at length. 



Discussion. 



Dr. Du Biche Preller observed that the juxtaposition of the 

 serpentine and what the Author described as ' white ' granite was 

 very similar to the occurrence in the Island of Elba, where the 

 celebrated white-mica granite was very valuable for the manufacture 

 of glass. He therefore wished to ask the Author whether the 

 granite in Anatolia was also quarried. The younger Elban granites 

 and serpentines were intrusive in Eocene limestone and sandstone, 

 and were therefore Tertiary, and, if the Author's section was correct, 

 this appeared to be also the case in the Anatolian rocks. 



The Author, in reply, said that he was not aware of the granite 

 being worked commercially. As a- rule, the mineral resources of 

 Asia Minor were very much neglected.
