Up to the time when James Ball entered the witness-box, the whole case had been dead against the prisoner. Even the grave doubts which the cross-examination raised about the housekeeper's veracity had passed unsubstantiated by any further evidence or proof; and the cook's story of the footstep on the stairs died out of all reckoning in the modicum of balance left in favor of the accused man when Davis, the chemist, had closed his evidence. But when his luckless assistant got down, after making such astounding admissions, we breathed again, and hopes that had been trampled under foot rose once more with renewed buoyancy. The rigid face of Serjeant Donaldson relaxed into anxious gravity, and the frank, genial countenance of Mr. Forster--Hugh Atherton's contemporary, and at whose side he had fought many a legal battle--shook off its cloud as he sat down and conferred with his senior colleague; whilst I heard a deep sigh of relief burst from Merrivale as he uttered, "Thank God, we have got over _that_ rock!" Then Donaldson rose. I think I hear and see him still, that grey-headed serjeant, with his rugged Scotch features lighted up by all the earnestness of his will, all the acute intelligence of his mind, as he turned to the jury, and in a voice tremulous with emotion, though it failed not to set forth the firmness of his purpose, and the honest conviction of his soul, opened his defence of Hugh Atherton. "Though standing at this bar," said Serjeant Donaldson, "with a heavy cloud of accusation overshadowing his hitherto stainless name, though branded by public opinion with the foul epithet of murderer, I can still call Mr. Atherton 'my friend' without a flush of shame; I can yet take him by the hand and feel proud to hail him brother by profession, companion in the same vocation. If," said the Serjeant, raising his voice and looking boldly around him, "the last witness had never been placed before you and made the remarkable revelation which you have all heard, I would still indorse what I have just said, and assert to you, my lords and gentlemen of the jury, my deep and heartfelt conviction of the innocence of the prisoner. But I have other and better grounds upon which to plead before you to-day--the only grounds upon which you can legally and conscientiously find a verdict."
