sition of these waters seems to be always nearly the same. In 

 particular, they all contain sulphate of soda ; and some, as those 

 of Sophia, a little sulphate of magnesia. They all indicate the 

 presence of more or less sulphuretted-hydrogen in a free state. 

 Others contain a little muriate of magnesia or lime, as those of 

 Banja, Aidos, and Sophia. I was unable to detect the presence 

 of carbonic acid or iron. Sometimes, but rarely, there are very 

 minute traces of lime, as at Banja. 



Temperature of Cold Springs. — At Alexinitza, in the low 

 hills of Southern Servia, a spring gave 13^° to 14° cent., the 

 temperature of the air being 17° ; at Jasen, in the lower part 

 of the hills south-east of Leskovatz in Mcesia, a spring was at 

 12°, whilst the air was at 17° in the shade, and at 26° in the 

 sun ; a fountain on the plateau of the neighbouring hills, at an 

 elevation of 900 feet, gave 16°, the air being at 19° ; near Tm 

 a spring was at 10°, and the air in the shade at 23° ; at Bresnik 

 one was at 10°, another at 11°, the air being at 28°, and a third at 

 15°, the air being at 18° ; in the plain of Sophia a spring was at 

 13°, the air in the shade at 18°; at Sopot, near Lofdtscha in 

 Bulgaria, at 12J°, and the air at 19°; at Csatak, in a valley of 

 the Balkan, at 13^°, the air being at 23° in the shade, and 26^ 

 in the sun during the month of June; at Karasholi, near 

 Osmanbazar, at 11°, the air being at 22° in the shade, and 31° 

 in the sun ; at Schumla at 12°, the air at 18° in the shade; at 

 Rodosto (Tekirdagh), on the Sea of Marmora, at 18°, the air 

 being at 26° ; on the Tekirdagh plateau, south of Kodosto at

 was at 12° or 13°, the air being at 28° in the month of August ; 

 at Scutari in Albania, the water of a deep well gave 12°, the 

 air being at 29° ; at Mokro, in the low hills, not far from Bosna- 

 Serai in Bosnia, and at an elevation of 2700 feet, a spring was 

 at 12°, the air being at 8° during September. 



These are the chief facts collected during my travels in 1837. 

 Geographers may doubt some of my positions, and it is possible 

 that I may have committed some errors ; but I had this in my 

 favour, that I was able to converse with the natives of each 

 country in their own languages, and that, in addition to a strong
