Stockholm, in so far as they are connected with the above men- 

 tioned coasts. My best thanks are due to Professor Nathorst and 

 Professor Wittrock in Stockhohn for their kind assistance. I 

 hkewise would express my gratitude to the Danish authorities and 

 persons луЬо have helped me in revising my material. 



It is my intention to give a further report of the expedition 

 itself and the accompanying circumstances in the detailed descrip- 

 tion of my journey which will make a continuation of my „flora", 

 and in which I also mean to give an account of the difficulties I 

 had to overcome, especially before my last journey, and of the 

 institutions and people who have lent me their weighty and valuable 

 assistance, without which I should hardly have been able to fulfil 

 the task I had taken upon myself.
