Page:The tale of two travellers.djvu/6

6 research if only represented by a few variants, Professor Kaarle Krohn in Helsingfors enabled me to use a graduale thesis by : „ “ (Truth and Lie or the two Travellers). ThankThanks [sic] to this efficient work, I got admission in a very easy way to the exceedingly rich Swedish-Finnish and Finnish material (about one fourth of the whole) which with very few exceptions has not come forth in print. Some of the results of Lempi Kaila’s investigations have of course at the same time been of use and help to me during the working out of this study, while on the other hand no real co-operative work could be established as the much bigger number of variants underlying my work made it a necessity to take up the matter anew. Where therefore the work of Magister Kaila differs from my conclusions, I have in foot-notes shortly accounted for these diversities.

Finally I bring my best thanks to all who have helped me in collecting the variants. Especially I must acknowledge my obligations to Professor Dr. J. Bolte and A. von Löwis of Menar in Berlin, Professor J. Polivka and V. Tille in Prague; teacher at the university of Lund Dr. C. W. v. Sydow and Dr. A. Aarne in Helsingfors.
