From these experiments 15 grs. of chloride of calcium in an ounce of water pro- 

 duced no, or very little, effect in two hours and a half; 22 grs. in rather more water 

 produced an increase in two hours and a quarter ; 30 grains produced a still more 

 marked increase in the same time, and the effect continued to be perceptible for at 

 least ten hours. 



(21.) Breakfast as before, with rather more meat. 30 grains of dry sulphate of 

 magnesia were taken at 1 o'clock in about an ounce and a half of distilled water.
