"I meant, rather, the very interesting general truth that is contained in Britton's statement; that physiognomy is not a mere matter of facial character. A man carries his personal trademark, not in his face only, but in his nervous system and muscles—giving rise to characteristic movements and gait; in his larynx—producing an individual voice; and even in his mouth, as shown by individual peculiarities of speech and accent. And the individual nervous system, by means of these characteristic movements, transfers its peculiarities to inanimate objects that are the products of such movements; as we see in pictures, in carving, in musical execution and in handwriting. No one has ever painted quite like Reynolds or Romney; no one has ever played exactly like Liszt or Paganini; the pictures or the sounds produced by them, were, so to speak, an extension of the physiognomy of the artist. And so with handwriting. A particular specimen is the product of a particular set of motor centres in an individual brain."

"These are very interesting considerations, Thorndyke," I remarked; "but I don't quite see their present application. Do you mean them to bear in any special way on the Blackmore case?"

"I think they do bear on it very directly. I thought so while Mr. Britton was making his very illuminating remarks."

"I don't see how. In fact I cannot see why you are going into the question of the signatures at all. The signature on the will is admittedly genuine, and that seems to me to dispose of the whole affair."

"My dear Jervis," said he, "you and Marchmont are allowing yourselves to be obsessed by a particular fact—a very striking and weighty fact, I will admit, but still, only an isolated fact. Jeffrey Blackmore executed his will in a regular manner, complying with all the necessary formalities and conditions. In the face of that single circumstance you and Marchmont would 'chuck up the sponge,' as the old pugilists expressed it. Now that is a great mistake. You should never allow yourself to be bullied and browbeaten by a single fact."

"But, my dear Thorndyke!" I protested, "this fact seems to be final. It covers all possibilities—-unless you can suggest any other that would cancel it."

"I could suggest a dozen," he replied. "Let us take an instance. Supposing Jeffrey executed this will for a wager; that he immediately revoked it and made a fresh will, that he placed the latter in the custody of some person and that that person has suppressed it."

"Surely you do not make this suggestion seriously!" I exclaimed.

"Certainly I do not," he replied with a smile. "I merely give it as an instance to show that your final and absolute fact is really only conditional on there being no other fact that cancels it."

"Do you think he might have made a third will?"
