into an aquatic one, or otherwise; and that the evolution happened 
less rapid, or even, geologically spoken, very slowly, where the 
animals remained terrestrial or aquatic beings, and only changed 
their manner of living in so far, that they became troglodytes or 
semi-troglodytes, or became from carnivorous only piscivorous or 
semi-carni-semi-piscivorous. I believe that by this hypothesis the 
problem is solved why remains of Basilosaurus are already found 
in Eocene layers together with remains of Viverrine ancestors of 
Carnwora, Pinnipedia and Basilosaurus, whilst those of true Pin- 
nipedia, Lutrina and Mustelina appear for the first time during 
the Miocene period, and whilst remains of true Vuverra’s (the 
genus) do not seem to have made their appearance before the 
Pliocene period. 
APPENDIX. 
Since the book was written, I have corresponded with Prof. Dr. 
M. Forstrr Hrppie, of St. Andrews, Mr. J. A. Harviz Brown, 
of Dunipace (Larbert), Misses Kare and Forses J. Macraz, both 
of Heathmount (Inverness), Mr. Gitpert Boerz, of Newcastle-on- 
Tyne, Prof. R. Cotuerr, of Christiania, and Mr. R. P. Grac, of 
Coles (Buntingford). The five first-named corresponded with me as 
eye-witnesses, and kindly sent me their statements, written immed- 
lately after the appearances they had witnessed; Prof. Convert 
courteously presented me with a copy of his dissertation Lid¢ om 
Soe-Ormen eller Soe-Slangen; Mr. Grea who since many years has 
been collecting with great zeal accounts and reports concerning the 
matter, had the rare liberality to send me his whole collection to 
make use of. To all these ladies and gentlemen I feel here called 
upon to tender my warmest thanks. 
Space does not allow me to give a verbal reprint of the various 
hoaxes, would-be sea-serpents, reports, and principal contents of 
papers, nor to treat of them separately. This I leave for an even- 
tual second edition. But all the appearances which I have placed 
under the Reports and Papers are explicable by reference to the 
Megophias. With the initials “R. P. G.” I have marked those 
statements, accounts, etc., which I got from Mr. R. P. Grue.

the subsequent parts, the following are additions to my first chapter:
