lens showed lithium very distinctly in the aqueous 

 extract, but not otherwise. The blood and bile were 

 very rich in lithium. The stomach was moderately 

 full of food. 



The other animal, which was given half a grain, 

 was kept until the lithium ceased to appear in the 

 urine. 



Fourth day. Lithium distinctly in the urine. 



Tenth day. Urine showed exceedingly minute 

 traces of lithium. 



Eleventh day. Still traces. 



Thirteenth day. Urine shows no lithium in the 

 quantity adhering to the wire. 



Fourteenth day. Still lithium in the alcoholic 

 extract. 



Twenty-seventh day. Still traces of lithium. 



Thirtieth day. The animal was found dead. 



The ash of the urine found in the bladder (about 

 a quarter of an ounce) showed no lithium. The 

 alcoholic extract of the ash showed lithium faintly. 

 The alcoholic extract of the ash of one kidney 

 showed no lithium. And the alcoholic extract of 

 the two lenses showed no lithium. 



Experiment 21. Two guinea-pigs, the urine of 

 which contained no lithium, were each given one 

 quarter of a grain of chloride of lithium. 



One was killed in four hours and thirty-five 

 minutes. Lithium was found very faintly in the 

 spleen, very distinctly in the blood, in the urine, 

 and in the bile. Faintly in the sciatic nerve and in 

 the brain. Very faintly in the scrapings of the 

 cartilage. Pretty distinctly in the vitreous and
