The result of these experiments is easily seen in Table XXL It follows therefrom 
that liquor potassse, taken in large doses, produces a decided effect in diminishing 
the acidity of the urine. 
It by no means renders the urine constantly alkaline, and its effect on the urine 
seems rapidly to pass away. Notwithstanding the large quantity of liquor potassee 
taken, the influence of food appears very evident ; before each meal the acidity was 
highest ; after each meal the alkalescence was greatest. 
The acidity of 1000 grains of urine was rarely more than sufficient to neutralize 
one grain of dry and pure carbonate of soda ; and the alkalescence was more than 
equal to a grain and a half of carbonate of soda in 1000 grains of urine. 
The conclusion from these experiments is, that an ounce of liquor potassse taken 
in three days does not counteract or conceal the influence of the stomach on the re- 
action of the urine. 
III. (c.) The effect of tartaric acid on the acidity of the urine was then examined. 
Some splendid crystals of tartaric acid were given to me by Mr. Morson. These 
were dried, reduced to a fine powder and heated in a water -bath until they ceased to 
lose weight ; a weighed quantity was dissolved in distilled water. 
(25.) The first day for comparison no tartaric acid was taken. Breakfast at S'* 45“a.m. 
Dinner at 6^ 10"* p.m. Mixed diet.
