300 metres higher than its present level. He resumes his view as 
follows (Nivåforandringer p. 683): ,,.... the littoral shell-banks of 
the continental platform along the Norwegian west coasts at the 
depths of 100—200 metres: on Storeggen, outside the mouth of 
the Sognefjord, at Tromsø, .... are compared with corresponding 
littoral shellbanks on the continental platform to the south-west of 
Ireland (Godwin Austen 1849), at Rockall (the Rockall Expedition 
1896—97), and off the Færoe Islands (the Danish Ingolf Expedi- 
tion, 1898, A. 8$.Jensen). An attempt is made to prove that all 
these littoral shell-banks at depths of from 100 to 300 m. are to 
be referred to the last interglacial time, probably to the latest part 
of-it; the continental platform must at that time have been uplifted 
about 100—300 metres higher than it is at present. 
It is assumed, that this uplift has continued during the last 
covering of Norway with a great ice-sheet". 
There is, however, no doubt that the occurrence of dead shallow 
water shells outside the vertical range of their respective species is even 
a much more common phenomenon than Professor Brøgger has main- 
tained"). The phenomenon presents itself at all the coasts 
1) In a previous paper (1. c. 1901) I have drawn the attention to the 
fact that dead shells in various lakes have been found at much greater 
depths than the living molluses of the corresponding species. In the 
»Nachrichtsblatt d. Deutsch. Mal. Gesell.” for September—Oktober 1901 
Mr. H. Sell has inserted a note to the effect that I have published 
the results of his researches with regard to the Fursø in Sealand, 
after he had shown them to me, and when I had promised him not 
to publish anything about it. This charge I must put down as quite 
alse. In November or December 1900 I asked the permission of 
Mr. Sell to work out some molluscs dredged by him and Mr. P. And er 
sen in the Fursø. Mr. Sell who at that period seemed very kindly 
disposed towards me did not take any reservation against my publishing 
whatever I wished on these Mollusces; on the contrary, he gave without 
hesitation his permission, only with the one restrietion that if men- 
tioning Hydrobia ventrosa, which had not been dredged before in the 
Fursø, I was to give his name. As a matter of course I did not omit 
to communicate that among the molluses at my disposal 
I had also availed myself of Mr. Sell's material. — When Mr. Sell has 
made an attack upon me, as the above named, or when he has tried
