entire lens was taken at one time on the wire. The 

 toe-nails showed lithium very distinctly. 



Another had three grains injected under the skin 

 of the neck, and it was killed in ten minutes. 



The humours of the eye showed lithium distinctly, 

 but the aqueous humour showed decidedly more 

 than the vitreous humour. The incinerated aqueous 

 extract of the lenses showed lithium very faintly. 

 The large nerves of the leg also showed lithium 

 very faintly. 



Another guinea-pig had a grain and a half of 

 chloride of lithium injected under the skin of the 

 neck, and in five minutes it was killed. The aque- 

 ous humour showed lithium distinctly. The vitreous 

 humour showed none. The blood and bile showed 

 lithium very distinctly. The kidney and urine 

 showed lithium faintly, and the liver very faintly. 



In another pig three grains of chloride of lithium 

 were injected into the skin of the neck, and the 

 animal was killed in four minutes. 



The blood and the bile showed lithium very 

 distinctly ; the blood showed it rather more than 

 the bile. The bladder contained only a few .drops 

 of urine, which showed lithium distinctly. The 

 kidney showed lithium fairly well. The liver 

 showed the lithium only very faintly, and in some 

 parts not at all. 



The aqueous humour showed lithium distinctly 

 The vitreous humour showed no lithium. 



So that, when injected under the skin 



3 grains in twenty-four minutes gave lithium in 

 the lens and everywhere.
