toms. The suspected paper was not removed, and the patient did not 

 recover." 750 c. c. urine, July 1, 1886, gave 0.005 mgr. to the litre. 



Case 17. (Drs. Putnam and Driver, Case 16.) "A variety of 

 serious symptoms were present, referable to the nervous system and 

 general nutrition, but Bright's disease was present, and for this reason 

 it would not have been thought worth while to report the case, but 

 that it is a question to be investigated whether arsenic may not occa- 

 sionally set up a chronic nephritis. The source of the arsenic was 

 not discovered." 1,080 c. c. urine, July 1, 1886, gave 0.055 mgr. 

 per litre. 



Case 18. (Drs. Putnam and Driver, Case 17). "Was that of a 

 school teacher, thirty-six years old, and in a rather nervous and debili- 

 tated state through her work, without, at first, any distinctly char- 

 acteristic signs of arsenical poisoning. During the summer months 

 immediately following this period, she spent most of her time out of 

 doors, and also chauged her room, and seemed on the high road to 

 recovery. In October, she returned to her former room, and immedi- 

 ately her old symptoms came back, and she was obliged to keep her 

 bed, suffering from ringing in the ears, sleeplessness, attacks of colic 

 at night, followed by diarrhoea, bad taste in the mouth, flatulent dys- 

 pepsia, irritation of the eyes and throat, and numbness of the hands. 

 On account of the character of the symptoms, and because they became 

 worse after the house was closed for a time and the furnace lighted, 

 arsenic was suspected and sought for. The paper in the room was 

 found to contain only a trace, but a frieze 20 inches wide and extend- 

 ing through three stories, gave 15 grains per square yard, and it was 

 observed that the hallway formed a sort of shaft through which the 

 heated air was conducted to the patient's bedroom, which was protected 

 only by a portiere, with an open space at the top. Furthermore, a 

 small trunk room, the door of which opened next to hers, and which 

 was used, with its window open, to ventilate her room, had. an old 

 paper wich border and figure of Paris green. . . . The paper has 

 been removed and the patient's gastric symptoms and sleeplessness are 

 much relieved, though she is still under treatment." July 25, 1886, 

 760 c.c. of the urine contained 0.018 mgr. arsenious oxide per litre. 



Case 19. (Drs. Putnam and Driver, Case 12). '-Was interesting 

 from the fact that here also were periodic attacks of gastralgia, 

 occurring this time at night, but in addition occasional outbreaks of 

 colic and diarrhoea. Insomnia and debility were also present. There 

 were no other especially characteristic symptoms." May 26, 1886, 

 960 c c. urine gave 0.01 mgr. per litre.
