SANGER. — CHRONIC ARSENICAL POISONING. 163 



material. No recurrence of the symptoms was experienced on return 

 to the house. Samples of the urine could not be obtained immedi- 

 ately after removal of the paper, or during convalescence, but in 

 October the urine was free from arsenic. 



Case 5. Mr. F., for six years previous to 1886, had occupied a 

 large, dry, sunny room, and generally spent sixteen to eighteen hours 

 each day in it. Two or three years before the report of the case, 

 several stuffed birds and animals, preserved by the free application of 

 arsenious oxide, were placed in the room. The wall paper contained 

 5.7 mgr. per sq. m. (0.073 gr. per sq. yd.), and the border 0.4 mgr. 

 (0.005 gr.). The paper of an adjoining bedroom contained 23.1 mgr. 

 per sq. m. (0.3 gr. per sq. yd.). The analysis of the last was made 

 from a sample taken from the wall, with portions of an old, adhering, 

 underlying paper. Mr. F., for nine months prior to April, 1886, 

 " noticed perceptibly a train of nervous disturbances, as occasional 

 attacks of dizziness and unsteadiness, a feeling of depression, and loss 

 of muscular power. He suffered also from a constant coryza, and a 

 dry cough. He had no gastric or intestinal disturbance." The pres- 

 ence of the birds suggesting a possible explanation of the symptoms, 

 1,500 c.c. urine were anahyzed April 12, 1886, and contained 0.03 mgr. 

 arsenious oxide per litre. The birds were removed and the walls and 

 room cleaned, but the papers were left on the walls. April 26 (14 

 days) 1,350 c.c. showed 0.026 mgr. per litre. Mr. F. improved in 

 general health after removal of the preparations, but the elimination 

 of arsenic was apparently slow. June 1 (50 days), 1,220 c.c. gave 

 0.002 mgr. per litre. June 14, Mr. F. began to take five grains potassic 

 iodide three times daity, which seemed, as in the above cases of Lo- 

 rinzer and Miiller, slightly to increase the elimination, as on June 21 

 (71 days) the amount from 1,320 c.c. was at the rate of 0.006 mgr. 

 per litre. Yet on July 16 (96 days) there was still a trace, 1 270 c.c. 

 giving 0.002 mgr. per litre. This is possibly explained by the pres- 

 ence of the wall papers, or by the fact that the carpets had not been 

 shaken. The iodide was discontinued, and Mr. F. went away for two 

 months, returning " feeling very well physically, the symptoms al- 

 luded to having mainly disappeared." 



Case 6. This is Case 13, reported by Dr. S. W. Driver of Cam- 

 bridge, in Putnam's paper.* " The case was one of severe and 

 painful inflammation in the abdominal cavity, with constipation and 

 loss of strength, . . . but it was difficult to say what symptoms, if any, 

 were to be attributed to its [the arsenic] influence."
