with Objective-Subjective and Subjective-Objective inextricably entangled together in my mind and I began the day which was to witness my next effort at practical action of some kind by doubting whether I had any sort of right (on purely philosophical grounds) to consider any sort of thing (the Diamond included) as existing at all.

How long I might have remained lost in the mist of my own metaphysics, if I had been left to extricate myself, it is impossible for me to say. As the event proved, accident came to my rescue, and happily delivered me. I happened to wear, that morning, the same coat which I had worn on the day of my interview with Rachel. Searching for something else in one of the pockets, I came upon a crumpled piece of paper, and, taking it out, found Betteredge's forgotten letter in my hand.

It seemed hard on my good old friend to leave him without a reply. I went to my writing-table, and read his letter again.

A letter which has nothing of the slightest importance in it, is not always an easy letter to answer. Betteredge's present effort at corresponding with me came within this category. Mr. Candy's assistant, otherwise Ezra Jennings, had told his master that he had seen me; and Mr. Candy, in his turn, wanted to see me and say something to me, when I was next in the neighbourhood of Frizinghall. What was to be said in answer to that, which would be worth the paper it was written on? I sat idly drawing likenesses from memory of Mr. Candy's remarkable-looking assistant on the sheet of paper which I had vowed to dedicate to Betteredge--until it suddenly occurred to me that here was the irrepressible Ezra Jennings getting in my way again! I threw a dozen portraits, at least, of the man with the piebald hair (the hair in every case, remarkably like), into the waste-paper basket--and then and there, wrote my answer to Betteredge. It was a perfectly commonplace letter--but it had one excellent effect on me. The effort of writing a few sentences, in plain English, completely cleared my mind of the cloudy nonsense which had filled it since the previous day.

Devoting myself once more to the elucidation of the impenetrable puzzle which my own position presented to me, I now tried to meet the difficulty by investigating it from a plainly practical point of view. The events of the memorable night being still unintelligible to me, I looked a little farther back, and searched my memory of the earlier hours of the birthday for any incident which might prove of some assistance to me in finding the clue.

Had anything happened while Rachel and I were finishing the painted door? or, later, when I rode over to Frizinghall? or afterwards, when I went back with Godfrey Ablewhite and his sisters? or, later again, when I put the Moonstone into Rachel's hands? or, later still, when the company came, and we all assembled round the dinner-table? My memory disposed of that string of questions readily enough, until I came to the last. Looking back at the social events of the birthday dinner, I found myself brought to a standstill at the outset of the inquiry. I was not even capable of accurately remembering the number of the guests who had sat at the same table with me.

To feel myself completely at fault here, and to conclude, thereupon, that the incidents of the dinner might especially repay the trouble of investigating them, formed parts of the same mental process, in my case. I believe other people, in a similar situation, would have reasoned as I did. When the pursuit of our own interests causes us to become objects of inquiry to ourselves, we are naturally suspicious of what we don't know. Once in possession of the names of the persons who had been present at the dinner, I resolved--as a means of enriching the deficient resources of my own memory--to appeal to the memory of the rest of the guests; to write down all that they could recollect of the social events of the birthday; and to test the result, thus obtained, by the light of what had happened afterwards, when the company had left the house.

This last and newest of my many contemplated experiments in the art of inquiry--which Betteredge would probably have attributed to the clear-headed, or French, side of me being upper-most for the moment-- may fairly claim record here, on its own merits. Unlikely as it may seem, I had now actually groped my
