The pathological and anatomical facts were, however, in themselves, so striking and satisfactory, that not the slightest doubt can exist as to the cause of the sufferings and death of the deceased; while, as _Mr. Murray_ very justly states, the high probability, arising from the separate symptoms of each individual, is strengthened almost to certainty, by the simultaneous occurrence of these in a whole family of four persons; while no similar disease, indeed no epidemic of any kind, prevailed at that time. We have only to add that the brother-in-law of this family was, in October, 1821, tried before the Judiciary Court at Aberdeen, for administering poison to his four relations; when the testimony given by the medical witnesses induced the judge and jury to consider the abstract act of poisoning proved. The accused afterwards confessed his guilt, and that he perpetrated the crime by means of _Arsenic_, put among the salt on the sunday morning on which the family were taken ill. The public, and the profession, are greatly indebted to _Mr. Alexander Murray_ for the details of this instructive case; and the patient attention and judgment with which he conducted the investigation, deserve the highest commendation, and afford an example which we sincerely hope future practitioners will endeavour to follow. Q. V. _What degree of information can be derived from administering the contents of the stomach of a person supposed to have been poisoned, to dogs, or other animals?_
