SANGER. — CHRONIC ARSENICAL POISONING. 105 



Case 9. (Case 11, Driver-Putuam.) M., aged 19, sister of N. J., 

 occupied same room, but was away from home during the day, while 

 her sister N. remained at home, made the beds daily, and swept and 

 dusted the room once or twice each week. Dr. Driver notes symp- 

 toms : '• Dyspepsia, irritated eyes for which she went to the eye and 

 ear infirmary, poor appetite, recurring pustules in outer meatus of ear. 

 Would feel wretchedly for two or three days at a time." The urine, 

 examined May 5, contained 0.028 mgr. per litre. The difference in 

 amounts is interesting, from the fact that M. spent less time under the 

 influence of the paper than N. did, and that she was less affected. As 

 iu the case of her sister, recovery followed the removal of the paper. 



Case 10. Miss G., aged 30, occupied a small room in a seaside 

 hotel, the paper of which contained 185 mgr. per sq. m. (2.37 gr. 

 per sq. yd.), and the border 134 mgr. per sq. m. (1.72 gr. per sq. } T d.). 

 The areas of paper and border were, respectively, 27.7 sq. m. (33.08 

 sq. yd.) and 1.86 sq. m. (2.22 sq. yd.). Connecting with this room 

 was another, on which was 23.4 sq. m. (27.95 sq. yd.) of the same 

 paper and 1.86 sq. m. (2.22 sq. yd.) of the same border. For about 

 a month after taking the room, the occupant was never free from 

 indigestion. There were occasional severe pains in the bowels with 

 constantly recurring diarrhoea. The first room had but one window 

 and the circulation of air was poor. The occupants of the second 

 room were apparently not affected, but it must be taken into account 

 that this room had three windows and was well aired. The walls of 

 both rooms were covered with a glue " size," and the symptoms soon 

 began to abate. The urine was not obtained until six days after the 

 size was put on. It then contained 0.054 mgr. per litre. During the 

 rest of the summer no return of symptoms occurred except occasional 

 slight indigestion. 



Case 11. S. H., a girl aged six, had occupied for over a year a room 

 of which the paper contained arsenic, but the amount was not deter- 

 mined. During the spring of 1886 the child began to show a capri- 

 cious appetite, with signs of digestive disturbance. The family took a 

 house at the seashore on July 3, and S. occupied with her brother 

 (Case 12) a room on the lower floor, the paper of which contained 

 313.5 -mgr. per sq. m. (4.01 gr. per sq. yd.), the border containing 

 128 mgr. (1.63 gr.). No other symptoms were developed, but 

 the indigestion became more marked. August 7, 860 grams of the 

 urine contained 0.019 mgr. per litre. On this day both children were 

 removed to a communicating room, merely for a change, the differ- 

 ence in the amount of arsenic not then being established. Little
