[217] Büdös is elsewhere described as a pointed cone of trachyte 3745 feet high, a solfatara or volcano, which, though never in actual eruption, incessantly pours forth streams of sulphuretted hydrogen gas, and these act as vents for the forces generated in the depths of the earth.

[218] The following is the analysis of the aluminous earth near Büdös:

Sulphuric acid,51·59per cent.
Water and sulphuric clay, mixed with lime,3·54”
