N.B.--From this date recovery slow but steady. 6.--_Memorandum by Mr. Henderson._ From the very vague nature of the foregoing evidence, so far as dates are concerned, it was, as you will at once perceive, no very easy task to determine the precise day of Madame R**'s first attack. To the view of the case, however, which I was even then inclined to adopt this was a matter of the last importance, and I determined to spare no effort to elucidate it if possible from the very loose data furnished by the depositions. In this I have, I think, been successful; but, as the process has been somewhat complicated, I must ask you to follow me through it step by step. The difficulty of tracing the truth seemed at first sight not a little augmented by the fact that no one had been in the house but Mrs. Brown herself, whose memory, even had it afforded any clue, could not have been relied on. On further consideration, however, I began to fancy myself mistaken in this respect, and finally conceived a hope that this very fact might, if properly handled, prove an assistance instead of an obstacle to my investigation. The following was the course of reasoning I pursued. There are only two points on which Mrs. Brown appears to be certain; her son's presence in England, and her being herself alone in the house on the actual day in question. The only chances of success therefore seemed to be:--First, in ascertaining precisely the limit of time within which such a combination was possible; and, second, in determining by a process of elimination the actual day or days on which such a combination could fall. The result has been far more complete than at the outset of the investigation I could venture to hope. 1st. For the period of time to which our researches should be directed. This was obviously limited by the residence of Richard Brown in England, and my first efforts were therefore directed towards determining the exact dates of his arrival and departure. 1. On inquiry at Liverpool, I found that the only vessels which had arrived from Melbourne during the month of March, 1856, were as follows: Ship. Captain. Owners. Arrived. James Baines McDonald Jas. Baines & Co 4th March Lightning Enright " 24th " Emma Underwood Pilkington Bros 27th " Of these the James Baines left Melbourne on the 28th November, and the Lightning on the 28th December. The exact date of sailing of the Emma I have not been able to ascertain, but it is immaterial to the case.
