It was not in my power to determine the cause of the albumin- 
uria in the persons examined, but I took care to exclude cases of 
the accidental accumulation of mucus or pus in the urinary tract, 
and have included only four, viz., two soldiers and two of the old 
men. In none of the cases was the albuminuria due to cardiac or 
pulmonary diseases, and in very few was there occasion to suspect 
the existence of Bright’s disease. On the other hand, there were 
few cases whose clinical history corresponded to Pavy’s cyclical 
albuminuria or Moxon’s albuminuria of adolescents. 
Being anxious to supplement these observations, I asked two of 
my former assistants, who are well known to me as careful and 
accurate observers, Dr James Ritchie and Dr Graham Brown, to 
give me the results as to albuminuria met with in the last 200 cases 
which had been proposed for insurance in the two companies for 
which they are medical referees. The tests employed had been heat 
or cold nitric acid, and it was found that in one series of 200, 5 per 
cent, showed albumen, and in the other series only 1 per cent, did 
so. The former result corresponds pretty closely to what nitric acid 
revealed in my own series of young men following civil employments, 
but is considerably below the results brought out by Dr Munro in 
his American statistics. The second series gives a much lower 
percentage. 
It is interesting to compare the results obtained in my other cate- 
gories with those given by other observers. Leube found, among 
German soldiers examined during the forenoon and after marching, 
16 per cent, albuminuric. Van FToorden, at the same time of day, 
found it in 35 per cent. Capitan found it among French soldiers 
44*9 per cent., and I have found it among the Highlanders (includ- 
ing recruits) in 37 ‘55 per cent.
