"Undoubtedly it is Runic," said the Professor, bending his brows;"but there is a secret in it, and I mean to discover the key."
A violent gesture finished the sentence.
"Sit there," he added, holding out his fist towards the table."Sit there, and write."
I was seated in a trice.
"Now I will dictate to you every letter of our alphabet which corresponds with each of these Icelandic characters. We will see what that will give us. But, by St. Michael, if you should dare to deceive me-"
The dictation commenced. I did my best. Every letter was given me one after the other, with the following remarkable result:[3]
When this work was ended my uncle tore the paper from me and examined it attentively for a long time.
"What does it all mean?" he kept repeating mechanically.
Upon my honour I could not have enlightened him. Besides he did not ask me, and he went on talking to himself.
"This is what is called a cryptogram, or cipher," he said,"in which letters are purposely thrown in confusion, which if properly arranged would reveal their sense. Only think that under this jargon there may lie concealed the clue to some great discovery!"
As for me, I was of opinion that there was nothing at all, in it; though, of course, I took care not to say so.
Then the Professor took the book and the parchment, and diligently compared them together.
"These two writings are not by the same hand," he said;"the cipher is of later date than the book, an undoubted proof of which I see in a moment. The first letter is a double m, a letter which is not to be found in Turlleson's book, and which was only added to the alphabet in the fourteenth century. Therefore there are two hundred years between the manuscript and the document."
I admitted that this was a strictly logical conclusion.
"I am therefore led to imagine," continued my uncle,"that some possessor of this book wrote these mysterious letters. But who was that possessor? Is his name nowhere to be found in the manuscript?"
My uncle raised his spectacles, took up a strong lens, and carefully examined the blank pages of the book. On the front of the second, the title-page, he noticed a sort of stain which looked like an ink blot. But in looking at it very closely he thought he could distinguish some half-ef
