projection corresponds to the depression which constitutes the 
grove of the wing of the nose. 
“ By dilating the nostrils, the ulcerations may be seen with 
their grayish and bloody surface; sometimes there is perforation 
of the cartilage. Delpech’s patient had a perforation 1.5 c.m. in 
width and 2 c.m. in length above the inferior border of the lower 
septum; this perforation extended to the perpendicular plate of 
the ethmoid. Another case cited by Rollet had an oval perfora¬ 
tion with a long antero-posterior diameter of 10 to 15 milli¬ 
meters, seated above the lower septum and on the anterior part 
of the median cartilage.” 
Dr. Thomas M. Legge, Medical Inspector of Factories, Home 
Office, in his evidence before the Royal Commission on Arsenical 
Poisoning, said, in substance : (6) 
In the manufacture of arsenical sheep dips, a peculiar condi¬ 
tion of erosion of the septum of the nose is brought about. The 
perforation is similar to that found very commonly among men 
working in factories where bichromate of potash is packed. The 
perforations cause permanent destruction of the part, but it is 
limited. It does not involve the whole of the septum of the nose, 
so that there is not much disfiguration in the cases where it has 
occurred. 
In his written statement submitted to the Commission, Dr. 
Legge said:(7) 
“ The manufacturers of sheep dip .—The manufacture is 
carried on in about ten factories and workshops, of which I have 
recently visited four. I append the results of the superficial ex¬ 
amination of 18 men employed in the largest of them. Perfora¬ 
tion of the septum of the nose had not been mentioned to me, in 
any of the factories visited, as one of the effects of the employ¬ 
ment. On the condition of No. 12 being noted, I was informed 
that they were the symptoms which would be presented by nine 
out of ten persons on commencing work. None of the men 
examined confessed to injury to health from their employment. 
Sheep dip is an arsenite of soda containing arsenic sulphate and 
free arsenious acid. The process of packing gives rise to con¬ 
siderable dust. * * *
