416 Dr. B. Jones on the Passage of Crystalloids [1865. 



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 entire lens was taken for a single examination, 

 the faintest possible indications of lithium were obtained. . 



Another patient five and a half hours before death drank lithia water 

 containing ten grains of carbonate of lithia. 



After death the cartilage of one joint and the crystalline lens were 

 examined. 



The cartilage showed lithium very distinctly. When half the lens was 

 taken for a single analysis, only very faint traces of lithium could be found. 



When no lithia had been taken, seven cataracts were examined most 

 carefully, and one only showed an exceedingly feeble trace of lithium. 



When twenty grains of carbonate of lithia were taken twenty-five minutes 

 before the operation, the lens showed no lithium ; the same quantity taken 

 two and a half hours before, showed lithium in the watery extract ; three 

 an da half hours before, showed lithium in each particle; between four and 

 five hours before, the same ; seven hours before, the same ; seven days 

 before, not the slightest trace of lithium. 



Thirty grains of carbonate of lithia, taken between six and thirty-six 

 hours before death, showed the faintest indications of lithium in the lens. 



Ten grains of carbonate of lithia taken five and a half hours before death, 

 gave only faint traces of lithium in the lens. 



On the Passage of Solutions of Lithium through the Textures after death. 



A sheep's eye was examined after death and no lithium could be detected 

 in any part. Two other eyes were placed in a solution of chloride of 

 lithium containing one grain to one litre of water. Twenty-three hours 

 afterwards the lithium was found to have penetrated through the entire
