The circumstances connected with her marriage and death are too well known, to require narrating here. Time has shown no clear light on the mystery. Mr. Laman Blanchard, in his memoir of her, has labored hard to prove that she did not die by the poison of prussic acid. His reasoning will not bear a moment's examination. That she died with a bottle in her hand, which contained it, he confesses is proved by other evidence than that of Mrs. Bailey, who first found her dead. He quotes Dr. Thomson, who furnished her order for her medicine-chest, and examined the list of articles actually put into it, and who also, on referring to the prescriptions written by him for her on former occasions, certified that on no occasion had he ordered her prussic acid. On this, Mr. Blanchard says, very innocently, how then could she possibly have got it? and adds, that very probably she was quite ignorant of its existence and nature; as he says he himself was! That is, that hydrocyanic acid was prussic acid! Unfortunately, the fact stands that she was found _by the surgeon_ with an empty bottle, labeled "hydrocyanic acid," in her hand, and was dead. "An empty bottle, though it bear on its label the words, 'hydrocyanic acid,' ceases to be a proof of her having taken any, when it is found there in her hand!" Poor Blanchard! How little did he think, in his generous desire to rescue his friend from the stigma of self-destruction, that no person, except himself, would require more conclusive evidence of the fact of a person's dying from the taking of prussic acid, than that of finding her dead on the floor, with an exhausted bottle of it in her hand! But, unfortunately, there are other facts which, however we may conclude as to the circumstance of her having thus taken it willfully, leave us no doubt of her being well acquainted with the effects of this poison; of her being in the habit of keeping it; and of her having actually, years before, threatened to make a fatal use of this very remedy. In Ethel Churchill will be found her own recital of the Countess Marchmont distilling herself this very poison from the laurel, and keeping secretly by her this poison, for the purpose of self-destruction under certain circumstances. This shows, most unanswerably, that Miss Landon not only was well aware of the character of this poison, but of the mode of its preparation. She does not send her heroine at once to the druggist's shop for it; though scores, as is too well known, have found no difficulty in procuring it there; but she details to us the process of its distillation, bottling, and secreting for use.
