Sometimes there are likewise present signs of irritation of the lungs and air-passages,—almost always shortness of breath (which, however, is chiefly owing to the tenderness of the belly),—often a sense of tightness across the bottom of the chest, and more rarely decided pain in the same quarter, darting also through the upper part of the chest. Sometimes pneumonia has appeared a prominent affection during life, and been distinctly traced in the dead body.[[617]]
In many instances, too, the urinary passages are affected, the patient being harassed with frequent, painful and difficult micturition, swelling of the penis, and pain in the region of the bladder, or, if a female, with burning pain of the vagina and excoriation of the labia.[[618]] Sometimes the irritation of the urinary organs is so great as to be attended with total suppression of urine, as in a case related by Guilbert of Montpellier, in which this symptom continued several days.[[619]] During the late contentions among chemists, physiologists, and physicians, occasioned by the case of Madame Lafarge, it was alleged by Flandin and Danger that in animals the urine is always suppressed, by Orfila that it is always secreted, by Professor Delafond of the Alfort Veterinary School, that it is never suppressed, but always diminished, and sometimes even to a sixth of the natural quantity.[[620]] There is, however, no invariable rule in the matter. And in fact, urinary symptoms are seldom present unless the lower bowels are likewise strongly irritated; but are then seldom altogether wanting. They are rarely well marked in cases of the present variety, unless life is prolonged three days or more.
When symptoms of irritation of the alimentary canal have subsisted a few hours, convulsive motions often occur. They commence on the trunk, afterwards extend over the whole body, are seldom violent, and generally consist of nothing else than tremors and twitches. Cramps of the legs and arms, a possible concomitant of every kind of diarrhœa, is peculiarly severe and frequent in that caused by arsenic.
The general system always sympathizes acutely with the local derangement. The pulse commonly becomes very small, feeble and rapid soon after the vomiting sets in; and in no long time it is often imperceptible. This state is naturally attended with great coldness, clammy sweats, and lividity of the feet and hands. Another symptom referrible to the circulation which has been observed, though, very rarely, is palpitation.[[621]]
The countenance is commonly collapsed from an early period, and almost always expressive of great torture and extreme anxiety or despair; the eyes are red and sparkling; the conjunctiva often so injected as to seem inflamed; the tongue and mouth parched; and the velum and palate sometimes covered with little white ulcers.
Delirium sometimes accompanies the advanced stage, and stupor also is not unfrequent. Coma occasionally precedes death, as in Mr. Stallard’s case (p. [235]), in which the symptoms of irritation, at first very violent, gradually gave place in two hours to complete insensibility, proving fatal in two hours more. Very often, however, the patient remains quite sensible to the last. Death in general comes on calmly, but is sometimes preceded by a paroxysm of convulsions.[[622]] In some cases it takes place quite unexpectedly, as if from sudden deliquium, as in a case mentioned by Dr. Dymock of this city. The patient, a girl who had taken two ounces intentionally, rose from her bed without help two hours and a half afterwards, went to a chair at the fireside, and had scarce sat down when she expired.[[623]]
Various eruptions have at times been observed, especially in those who survive several days; but they are more frequent in the kind of cases to be considered afterwards, in which life is prolonged for a week or more. The eruptions have been variously described as resembling petechiæ, or measles, or red miliaria, or small-pox. In the case already quoted from Guilbert a copious eruption of miliary vesicles appeared on the fifth day, and for fifteen days afterwards. They were attended with perspiration and abatement of the other symptoms, and followed with desquamation of the cuticle. Another external affection which may be noticed is general swelling of the body. Several cases of this nature have been described by Dr. Schlegel of Meiningen; and in one of them the swelling, particularly round the eyes, appears to have been considerable.[[624]]
In some cases of the kind now under consideration a short remission or even a total intermission of all the distressing symptoms has been witnessed, particularly when death is retarded till the close of the second or third day.[[625]] This remission, which is accompanied with dozing stupor, is most generally observed about the beginning of the second day. It is merely temporary, the symptoms speedily returning with equal or increased violence. Sometimes the remission occurs oftener than once, as in a case related in the London Medical and Physical Journal. The patient, a child seven years old, lived thirty-six hours in a state of alternate calm and excitement; and during the state of calm no pulse was to be felt at the wrists.[[626]]—So far as at present appears a long intermission is impossible.
In cases such as those now described death often occurs about twenty-four hours after the poison is swallowed, and generally before the close of the third day. But on the one hand life has been sometimes prolonged, without the supervention of the symptoms belonging to a different variety of cases, for five or six days,[[627]] nay perhaps even for several weeks. And, on the other hand, the symptoms of irritation of the alimentary canal are sometimes distinct, although death takes place in a much shorter period than twenty-four hours. Metzger has related a striking case, fatal in six hours, in which the symptoms were acute colic pain, violent vomiting, and profuse diarrhœa;[[628]] and Wildberg has related a similar case fatal in the same time.[[629]] Hohnbaum describes another fatal in five hours;[[630]] and I met with as brief a case in this city in 1843, where all the usual symptoms of irritation in the stomach and bowels were violent. These symptoms were also present at first in Mr. Stallard’s case, which was fatal in four hours; Pyl has recorded one, where all the signs of irritation in the stomach and intestines were present, except vomiting, and which proved fatal in three hours;[[631]] and Dr. Dymock met here with a similar instance which lasted only two hours and a half.[[632]] This is one of the shortest undoubted cases of poisoning from arsenic I have hitherto found in authentic records. Dr. Male mentions one, which was fatal in four hours;[[633]] Wepfer another equally short;[[634]] Johnston another fatal in three hours and a half;[[635]] and I shall presently mention others without symptoms of irritation which ended fatally in two, five, or six hours [p. [242]].[[636]] Wibmer has even quoted a case fatal in half an hour; but there seems to have been some doubt whether the poison taken was arsenic.[[637]]
Such is an account of the symptoms of poisoning by arsenic in their most frequent form. It will of course be understood, that they are liable to a great variety as to violence, as well as their mode of combination in actual cases;—and that they are by no means all present in every instance. The most remarkable and least variable of them all, pain and vomiting, are sometimes wanting. A case, in which pain was not felt in the stomach, even on pressure, although the other symptoms of inflammation were present, has been briefly described in the Medical Repository.[[638]] A similar case fatal in fourteen hours and a half, where there was much vomiting and some heat in the stomach, but no pain or tenderness, has been related by Dr. E. Gairdner.[[639]] Another very striking example of this anomalous deficiency has been detailed by Dr. Yellowly. A lad sixteen years old died twenty-one hours after swallowing half an ounce of the white oxide; and the presence of inflammation was denoted all along by sickness, vomiting, purging, and heat in the tongue; yet he never complained of pain, neither did he ever seem to his friends to suffer any. Another anomaly in the case was, that the pulse, contrary to what is usual, was very slow: twelve hours after he took the poison, the pulse was 40, and two hours before death it was so slow as 30.[[640]] These deviations from the ordinary course of the symptoms are taken notice of merely to put the practitioner on his guard, and prevent the medical jurist from drawing hasty conclusions. Upon the whole, they are rare; and the symptoms of poisoning by arsenic are in general very uniform.
