300 metres higher tlian 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 Au sten 1849), at Eockall (the Eockall Expedition 
1896—97), and off the Færoe Islands (the Danish Ingolf Expedi¬ 
tion, 1898, A. S. Jensen). An attempt is made to prove that all 
these littoral shell-hanks at depths of from 100 to 300 m. are to 
he 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 Norvvay with a great ice-sheet“. I 
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 
In a previous paper (1. c. 1901) I have drawn the attention to the 
faet that dead sbells in various lakes have been found at much greater 
depths than the living molluscs of the corresponding species. In the 
„Nachrichtsblatt d. Deutsch. Mal. Gesell.“ for September—Oktober 1901 
Mr. H. Se 11 has inserted a note to the elfeet 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 
false. In November or December 1900 I asked the permission of 
Mr. Seil to work out some molluscs dredged by him and Mr. P. Ander¬ 
sen in the Fursø. Mr. Seli who at that period seemed very kindly 
disposed towards me did not take any reservation against my publishing 
whatever I wished on these Molluscs; on the contrary, he gave without 
hesitation his permission, only with the one restriction that if men- 
tioning Hydrohia 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 
in my paper to communicate that among the molluscs at my disposal 
I had also availed myself of Mr. Sell’s material. — When Mr. Se 11 has 
made an attack upon me, as the above named, or when he has tried
