It is said that the barrister who crams up a case with such care that he can examine an expert witness upon the Monday has forgotten all his forced knowledge before the Saturday. Certainly I should not like now to pose as an authority upon ceramics. And yet all that evening, and all that night with a short interval for rest, and all next morning, I was sucking in knowledge and committing names to memory. There I learned of the hallmarks of the great artist-decorators, of the mystery of cyclical dates, the marks of the Hung-wu and the beauties of the Yung-lo, the writings of Tang-ying, and the glories of the primitive period of the Sung and the Yuan. I was charged with all this information when I called upon Holmes next evening. He was out of bed now, though you would not have guessed it from the published reports, and he sat with his much-bandaged head resting upon his hand in the depth of his favourite armchair.

“Why, Holmes,” I said, “if one believed the papers, you are dying.”
