190 APPENDIX III. 



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 distinctly ; 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 lithium very distinctly. A 

 small piece taken from the cartilage of the hip-joint 

 showed only traces of lithium.
