SANGER. 



CHRONIC ARSENICAL POISONING. 



167 



For several months Mrs. L. had suffered with severe neuralgic 

 pains, " accornpauied, from time to time, by a good deal of constitu- 

 tional disturbance." There was much gastric disturbance, with fre- 

 quent attacks of nausea and vomiting. On removal to another house 

 she began to improve and was getting much better, until, contrary to 

 the physician's advice, she occupied a room of which the paper was 

 arsenical (not sent to me for analysis). A return of the symptoms 

 followed. "When she finally took a room in which the papers were 

 examined and found free from arsenic, she began to get better again, 

 and since then had not shown any signs of a relapse. The urine, 

 taken GO days after removal from the first house, contained 0.01 mgr.

Case 15. (Drs. Putnam and Driver, Case 14.) "The patient, 

 being a lady of 58, showed, besides the more common symptoms of 

 impaired nutrition and digestion, numbness of the hands at times and 

 weakness in walking. In the presence of these symptoms, it is fair to 

 suspect that a searching physical examination of the muscles, and of 

 the sensibility of the skin might have justified a diagnosis of neuritis. 

 Without that, the numbness of the hands at least can only be counted 

 as a corroborative symptom. The source of the arsenic was not 

 traced, but the patient improved on leaving home and relapsed on 

 her return." 370 c. c. urine were analyzed July 14, 1886, and 

 the amount of arsenic found was 0.005 mgr. per litre. 



Case 16. (Drs. Putnam and Driver, Case 15.) " The patient 

 suffered from 'epileptic vertigo,' which was not, however, attributed 

 to the arsenic. She had also obscure digestive and nervous symp-
