There has also appeared in the "Deventer Courant" a series of twelve letters on the same subject. Though written anonymously, I believe they are from the pen of Professor Vitringa. They have been translated into German by Mr Otto. The writer evidently entered upon his task of criticism with a feeling of disbelief in the authenticity of the book; but in his last letter he admits that, after a minute examination, he is unable to pronounce a positive conviction either for or against it. His concluding remarks are to the following effect:-- "If the book is a romance, then I must admit that it has been written with a good object, and by a clever man, because the sentiments expressed in it are of a highly moral tendency; and the facts related, so far as they can be controlled by regular history, are not untruthful; and where they deal with events of which we have no historical records, they do not offend our ideas of possibility or even probability." Wm. R. Sandbach. INTRODUCTION. C. over de Linden, Chief Superintendent of the Royal Dockyard at the Helder, possesses a very ancient manuscript, which has been inherited and preserved in his family from time immemorial, without any one knowing whence it came or what it contained, owing to both the language and the writing being unknown. All that was known was that a tradition contained in it had from generation to generation been recommended to careful preservation. It appeared that the tradition rests upon the contents of two letters, with which the manuscript begins, from Hiddo oera Linda, anno 1256, and from Liko oera Linda, anno 803. It came to C. over de Linden by the directions of his grandfather, Den Heer Andries over de Linden, who lived at Enkhuizen, and died there on the 15th of April 1820, aged sixty-one. As the grandson was at that time barely ten years old, the manuscript was taken care of for him by his aunt, Aafje Meylhoff, born Over de Linden, living at Enkhuizen, who in August 1848 delivered it to the present possessor. Dr E. Verwijs having heard of this, requested permission to examine the manuscript, and immediately recognised it as very ancient Fries. He obtained at the same time permission to make a copy of it for the benefit of the Friesland Society, and was of opinion that it might be of great importance, provided it was not supposititious, and invented for some deceptive object, which he feared. The manuscript being placed in my hands, I also felt very doubtful, though I could not understand what object any one could have in inventing a false composition only to keep it a secret. This doubt remained until I had examined carefully-executed facsimiles of two fragments, and afterwards of the whole manuscript--the first sight of which convinced me of the great age of the document.
