contained lithium. The circulation through the 

 eye had been healthy, and the lens itself was 

 clear. 



Experiment 7. The soft lens of a girl aged four- 

 teen was examined after ten grains of carbonate of 

 lithia in water had been taken five hours before the 

 operation, and the same quantity four hours before 

 extraction. 



The smallest fraction of the lens showed the 

 lithium distinctly. 



Experiment 8. Another patient with two soft 

 cataracts took twenty grains of carbonate of lithia 

 seven hours before one operation ; but the capsule 

 of the lens had been previously broken, so as to 

 expose the cataract to the aqueous humour. 



Lithium was found very distinctly even in the 

 smallest particle of the cataract. 



Four days after the first operation the capsule of 

 the other lens was broken, so as to expose the 

 cataract to the aqueous humour; and seven days 

 after the first operation the second operation was 

 performed. 



In this cataract not the slightest trace of lithium 

 could be found. 



A woman with diseased heart drank some lithia 

 water, containing fifteen grains of citrate of lithia, 

 thirty-six hours before her death ; and six hours 

 before death she drank the same quantity. 



After death the crystalline lens, the blood, and 

 the cartilage of one joint were examined for lithium. 



The cartilage showed lithium very distinctly ; the 

 blood showed lithium very faintly ; and when the
