164 PROCEEDINGS OF THE AMERICAN ACADEMY. 



The only wall paper in the house was in the room where the patient 

 spent a great deal of his time, and the amount was 690 mgr. per sq. m. 

 (8.8 gr. per sq. yd.). The urine, analyzed May 18, 1886, contained 

 0.016 mgr. per litre, and June 16 (29 days), after removal of the 

 paper, 0.002 mgr. per litre. 



Case 7. This is one of the group reported in Putnam's paper by 

 Dr. J. T. G. Nichols of Cambridge, but the analysis of the urine 

 was not given. Dr. Nichols sends the following facts to me : " The 

 girl was about four years of age. She had indigestion, constipation, 

 and occasional vomiting. Insomnia was a marked symptom. She 

 had frequent attacks of sore throat, and was much troubled by eczema 

 of the vulva and anus. She was easily tired and very irritable. She 

 did not lose flesh nor color." The wall papers were examined by Pro- 

 fessor H. B. Hill. In the child's room was a blue frieze about six 

 inches wide containing 710 mgr. to the sq. m. (9.09 gr. per sq. yd.). 

 One of the other papers in the house contained 153 mgr. per sq. m. 

 (1.96 gr. per sq. yd), another 83 mgr. (1.06 gr.), while the rest were 

 but slightly arsenical. 



April 6, 1886, 250 c.c. urine gave an amount of arsenic equivalent 

 to 0.015 mgr. per litre. The papers were removed, and "gradual but 

 steady improvement soon began." The elimination was slow, but 

 I cannot say that all arsenical surroundings were removed. On 

 June 29 (84 days), 200 c.c. urine gave 0.012 mgr. per litre, and on 

 July 15 (100 days), 930 c.c. gave 0.008 mgr. per litre. The child had 

 no return of the symptoms after removal of the papers. 



The following cases are accompanied by analyses of the papers and 

 a single analysis of the urine. 



Case 8. This is Case 10, reported by Dr. Driver, in Putnam's 

 paper. Patient, N. J., a girl aged 17, and her sister (Case 9), occu- 

 pied a room of which the walls were covered by an old-fashioned 

 paper, with red flowers and green leaves, and bordered with a strip of 

 dark green two inches wide. The green was probably Scheele's or a 

 similar one. The paper contained 116.7 mgr. per sq. m. (1.48 gr. per 

 sq. yd.), and the border 1,200 mgr. per sq. m. (15.36 gr. per sq. yd.). 

 The health of both girls had been impaired for two years. Dr. 

 Driver noted to me the following in N. J.'s case : " Puffed and swollen 

 face, reminding one of the effects of ivy poisoning, anaemia, quick 

 pulse, 80 to 90, dizzy head, nausea, no appetite, dyspepsia. Slight 

 trace of albumen that soon disappeared. Grew better under diuretics 

 and tonics." The urine was analyzed May 5, 1886, and contained 

 0.068 mgr. per litre. On removal of the paper, recovery ensued.
