In addition to the references to the Swedish literature specifically 

 referred to above, the writer has also used -a pamphlet by Prof. A. 

 E. Tornebohm, Explanatory Remarks, to accompany the Geological 

 General Map of Sweden. This map, on a scale of 1 : 1,500,000, or 

 about 25 miles to the inch, has also been used. A much larger one 

 has been issued by the Swedish Survey. The members of the excur- 

 sions in connection with the Congress were furnished with excellent 

 guidebooks. The writer has especially drawn upon nos. 1-6, 15 

 and 18.
