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 

 tubs containing it they submerge themselves. A

 and myself that we should this year meet at Pontresina, 

 and without concert as to the day both of us reached 

 the village within the same quarter ot 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
