Swiss and Germans, and an increasing number of 

 English, congregate. The water contains carbonic acid 

 (the gas of soda water) and a trace of sulphate of iron 

 (copperas) ; this the visitors drink, and in elongated 

 tubes containing it they submerge themselves. A 

 curious effect is produced by the collection and escape

 the village within the same quarter of an hour. Some 

 theoretic points of glacier motion requiring elucida- 

 tion, we took the necessary instruments with us to the 

 Engadin; we also carried with us a quantity of other
