ticiilarly with the former, cannot admit of doubt. The very large diminution in the 
excretion of chloride of sodium under the action of alcohol corresponds with the 
lessened excretion of urinary water, so that the former fell 27'5 and the latter 28*7 per 
cent. The diminution was much greater than that of urea, which was only 5 per cent, 
on the average of the three days. 
9. Belation of the Excretion of Urea to headache, deranged stomach, and a 
sense of general malaise. 
I was not subject to any serious illness during the year, but on various occasions, for 
a day or two at a time, I had derangement of the stomach accompanied by headache, 
and much nervous irritability and depression. The observations which were then made 
show that this condition was commonly accompanied by lessened excretion of urea and 
urine, and the relief of it with increased excretion ; but the smaller amount of urea was 
not necessarily much below the average. I have tabulated the observations in the 
following manner for convenience of analysis : —

It is very likely that all the conditions above mentioned were not identical ; but they 
show that in all the attacks of illness whicli I had the elimination of urea was disturbed. 
Commonly the ehmination of urea was temporarily lessened, and had been above the 
average amount. The effect upon the urine was not uniform ; but the Aury largely 
increased elimination of urine, with lessened elimination of urea, in the two instances in 
which food disagreed were very striking. In every instance of headache the relief was 
attended by a return to the usual rate of elimination of urea. There Avas not, on those
