184 APPENDIX III. 



between the inner and outer part of the lens was 

 very marked. The second eye was not examined 

 for more than fourteen hours after the first eye. 

 After this time the centre of the lens contained 

 as much lithium as the outer part did. The stomach 

 contained water. 



Experiment 11. A young guinea-pig, fasting, 

 was given three grains of chloride of lithium, and 

 thirty-two minutes afterwards it was killed. Lithium 

 showed faintly in the cartilage of the hip-joint; 

 very distinctly in the humours of the eye; dis- 

 tinctly in the outer part of the lens, very faintly 

 in the inner part; nearly the whole of the inner 

 part had to be burnt to give the appearance. 

 Lithium was very distinct in the blood, and remark- 

 ably so in the nails. 



Experiment 12. Another young guinea-pig, fed 

 in the same way, and bought at the same place as 

 the two former, was killed without taking any lithia. 

 No lithium was found anywhere. The whole of the 

 spleen, one kidney, and one lens were incinerated, 

 and each ash was used for a single experiment, and 

 in no instance was lithium found. There was no 

 lithium in the cartilage of the hip-joint, nor in the 

 blood, nor in the nails. 



Experiment 13. A very young and small guinea- 

 pig that had been kept fasting for thirty-six hours, 

 was given three grains of chloride of lithium, and it 

 was killed in half an hour, the urine having been 

 previously examined, and no lithium found in it. 

 Very much lithium was found in the blood and in 

 the urine ; very slight traces in the cartilage and in
