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



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 inci- 

 nerated 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 

 aqueous 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. 



3 grains in ten minutes gave lithium in the lens and everywhere. 

 1J grain in five minutes gave lithium in the aqueous humour and in 

 the bile. 



3 grains in four minutes gave lithium in the aqueous humour and in the 

 bile. 



3. Experiments on the Rate of Passage of the Lithium out of the 

 Textures. 



Experiment 18. Five guinea-pigs were given two grains of chloride of 

 lithium each. They were killed at different periods ; the first in six 

 hours. The smallest particle of the lens showed the lithium very dis- 

 tinctly ; a decided difference, however, was detectable between the inner 

 and the outer part. The cartilage of the hip-joint showed lithium very 

 distinctly when touched with the red-hot wire. All the organs and the 

 blood showed lithium very abundantly. The stomach contained very 

 little solid food, but was half full of liquid. The second and third were 

 killed in twenty-four hours. The lenses of both showed the lithium very 

 distinctly; no difference was perceptible between the inner and the outer 

 part. The cartilage of the hip-joint showed no lithium when touched 

 with the red-hot wire ; but a small portion taken off the surface showed 

 lithium distinctly. 



The fourth guinea-pig was killed in forty-eight hours. The lens showed
