V.. aged : ^- has worked for twelve years (is4'.M in a chromate manufacturing 

 plant. He was employed from tlu> beginnim: at the grinder and sifter, and is thus 



constantly enveloped in an atmosphere charired with line elin>me-iron powder. He 

 says that he feels no indisposition. He wipes his nose ami s[)its Itlaekish matter, 

 luit neither roiurhs nor has any smotliere<l feeling; his health appears to be good; 



he has no diseasi- of the Innirs; he does not believe there is anything the matter 

 with his nose: however, his smse of smell was perfect when he entered the factory, 

 and he lias now completely lost it. The nasal j.a>si'j- wnv .\amined. and a per- 

 foration of tlu> cartilage was observed. He says that since entcrin-_r tin- facti'iy In- 

 has sometimes worked at the kettles. At the commencement of this labor he was 

 attacked with headache and swelling of the nose accompanied l.y an abundant dis- 

 charge from the nostrils. His eyes did not smart. These symptoms lasted about 

 fifteen days, after which he regained the most perfect health without even experi- 

 encing again the symptoms enumerated, although employed at the same work. 



This workman has since (October, 1804) died after a few days' illness of inflamma- 

 tion of the chest, without having previously shown any prolonged symptoms of suf- 

 fering with the respiratory organs.

\'... aged 2S, who had a good constitution, had been employed for five weeks in a 

 potassium bichromate manufacturing plant when he was examined by us. He was 

 employed about eight days inside the works carrying the bichromate and for three 

 weeks at the kettles. From the first day he was attack* d by prolonged ami intense 

 sneezing. After four days he suffered greatly with intense prickling, abundant run- 

 ning of the nose, an incessant desire to blow his nose, and the passage of red mem- 

 braneous shreds. He had no watering of the eyes, or at most it was slight. The 

 most severe sym i >toms lasted from ten to twelve days. He had nearly recovered 

 when he stopped working at the kettle, and has since completely recovered. This 

 workman still has his sense of smell. He was afflicted by a sore on his right hand, 

 caused by penetration of particles of bichromate in a slight excoriation, and a slight 

 ulceration still remains. One can also note brown spots, caused by sores of the same 

 nature, upon the side of his face and on the ring finger. 



E. has never suffered with his feet. He has no eruption either on the skin of his 

 body or genital organs. His eyelids are not excoriated, and he has neither vomited, 

 suffered with diarrhea, nor a cough. The nasal partition is perforated at the usual 

 place.
