186 APPENDIX III. 



The urine showed no lithium in one drop, but the 

 ash of the urine showed traces of lithium. No 

 lithium could be detected in any of the organs, not 

 even by treating the ash of the kidney with sulphuric 

 acid and alcohol. 



The two remaining animals were each given one 

 quarter of a grain of chloride of lithium. 



The first was killed in five and a quarter hours 

 afterwards. All the organs, except the lens of the 

 eye, showed lithium by simply touching them with 

 the red-hot wire. The urine and the bile showed 

 the lithium very distinctly. The blood showed 

 lithium faintly. The vitreous and aqueous humours 

 showed traces of lithium. An aqueous extract of 

 the lens showed no lithium. The animal was a 

 large and old one, and the stomach was nearly 

 empty. 



The second was killed twenty-four hours after 

 one quarter of a grain. 



None of the organs showed any lithium by simply 

 touching them with a red-hot wire. The ash of the 

 kidney showed traces of lithium, and so did the ash 

 of part of the liver. No lithium could be detected 

 either in the vitreous and aqueous humour, or in the 

 lens ; the urine and the bile showed lithium in one 

 drop, but only faintly. Possibly the lithium had 

 not been absorbed in this case. The state of the 

 stomach, as regards food, was not recorded. 



It follows from these experiments, that when no 

 lithium is taken no lithium can be found in the 

 different textures, but that even in a quarter of an 

 hour three grains of chloride of lithium given on an
