HOT SPRINGS 



As "hot springs" I have only included those which on the lahels 

 L have distinctly heen marked as such. I have of these 30 

 samples from 13 localities, viz. 



from S. : Grafarbakki (1 sampl.), Minni Laxi'i (4 sampl.), Torfastaöir 

 (4 sampl.). 

 » S.W.: Hrossholt (1 sampl.), Reykjavik (4 sampl.). 

 » N.W. : Hrutafjöröur (1 sampl.), Reykjanes (3 sampl.), Steingrims- 



fjöröur (1 sampl.). 

 •> N. : Akureyri (2 sampl.), Hrafnagil (4 sampl.), Hrisey (1 sampl.), 

 Laugafells Laug (3 sampl.), Reykjarfjöröur (1 sampl.). 

 In these I have found the following forms:
