 there found within the head any appearance corresponding with the symptoms, except occasionally a slight turgescence of vessels.

This form of apoplexy, then, is a very important affection in a medico-legal point of view. The possibility of its occurrence is in fact the chief obstacle, which, in many cases involving the question of poisoning with narcotics, prevents the physician from coming to a positive decision on a review merely of symptoms and appearances after death. Instances will occur where it is impossible to draw a diagnosis between the natural and the violent form of death. And indeed it might even be a fair subject of inquiry, whether death from at least some narcotic poisons, such as opium, is any thing else than death from simple apoplexy.

It may be mentioned,—although too much importance ought not to be attached to the fact, as forming the ground of a diagnosis in certain rapid cases of narcotic poisoning,—that of the instances of simple apoplexy referred to above none proved fatal in less than five hours. This was Dr. Gregory's case. Dr. Alison's proved fatal in seven hours; M. Louis's cases in eight, nine, and ten hours; one of Dr. Abercrombie's in eight hours; the three others in about twenty-four hours; and M. Lobstein's in five days.

Another consideration is, that simple apoplexy is undoubtedly very rare, more particularly in persons who enjoy perfect health. Hence, although it is impossible to distinguish the effects of narcotics from this disease by the appearances in the body after death, yet, when the general evidence of poisoning is strong, and none of the medical circumstances are at variance with the supposition of narcotic poisoning, the evidence of poisoning, as judged of by the jury from the whole facts, medical and general, will be commonly sufficient,—so far as regards the possibility of death from simple apoplexy. For such a concurrence of circumstances as is here supposed can scarcely be outweighed by a mere possibility of death from so rare a natural disease.

It is worthy of remark, in reference to charges and suspicions of poisoning during a state of ill health, that simple apoplexy occurring in the course of a considerable period of indifferent health is far from uncommon. Such incidents, however, ought not to be confounded with narcotic poisoning, because the coma comes on gradually. From what I have myself frequently observed, cases of this nature are often connected with the granular disintegration of the kidneys, which has been brought under the notice of physicians by the able researches of Dr. Bright. I have related two instances of the kind, and several others have been since published by Dr. James Arthur Wilson. In none of these could there have been any risk of mistaking the phenomena for narcotic poisoning. But it may be well to advert to the subject here for the sake of turning the attention of the profession to the propriety of examining the state of the kidneys in all medico-legal cases of death in a state of coma.
