166 PROCEEDINGS OP THE AMERICAN ACADEMY. 



or no improvement resulted. The paper in this room contained 

 109 mgr. per. sq. m. (1.41 gr. per sq. yd.), and the border had 2-1 mgr. 

 (0.31 gr). August 12, both rooms were sized with glue. The effect 

 was soon noticed and the child improved rapidly. 



Case 12. T. H., brother of S. H., aged four, had occupied a room 

 which contained but a trace of arsenic in the wall paper, and on 

 coming to the sea-shore house was perfectly well. Occupied same 

 room as his sister (Case 11), but no signs of a similar digestive dis- 

 turbanee showed themselves. August 7, he was removed with his 

 sister to the communicating room. About this time he had been 

 playing during the day with a red flag which was afterwards found to 

 contain 336 mgr. per sq. m. (4.08 gr. per. sq. yd.), and he kept it 

 with him for several days. August 9, he was attacked with diarrhoea, 

 accompanied by fever, which lasted for three days. The urine con- 

 tained 0.008 mgr. per litre. August 12, as mentioned above, both 

 rooms were glue sized, and for the rest of the summer there was no 

 further trouble. 



The other papers in the house were, with one or two exceptions, 

 highly arsenical. 



Case 13. Mr. J., a clergyman in good health, lived in a house 

 which was papered in the spring of 1885. Three of the papers con- 

 tained arsenic in considerable quantity; study, 40.6 mgr. per sq. m. 

 (0.5 gr. per sq. yd.) ; bedroom, 31.2 mgr. (0.4 gr.), and the third, which 

 1 believe covered the hall, 14.4 mgr. (0.18 gr.). Not long after the 

 rooms were papered, Mr. J. began to suffer from extreme languor and 

 diarrhoea, for which he could discover no satisfactory cause, either in 

 diet or daily habits. These continued until he left home for his vaca- 

 tion, and for six weeks he was in perfect health. On return, the 

 symptoms came back, accompanied by insomnia, dyspepsia, and swell- 

 ing of the hands and feet. Neither his local physician nor a New 

 York physician whom he consulted could assign a cause for what 

 seemed to them to be a case of poisoning. The analysis of the urine, 

 February 25, 1886, showed 0.01 mgr. to the litre. The walls were 

 stripped and the patient " treated for arsenical poisoning." Mr. J. 

 reported his health to me afterward as being improved, but, as he was 

 unwilling to pursue the matter further on account of publicity, the 

 record ceases here. 



Case 14. This case was reported to me by Dr. A. P. Clarke, of 

 Cambridge, and mentioned by him at the meeting of the South 

 Middlesex Society above referred to. Mrs. L., aged 51, occupied for 

 seven years a tenement, of which the papers, most of them quite old- 

 fadiioned, contained the following amounts of arsenic.
