APPENDIX III. 215 



It appears from these experiments that 

 Potatoes showed lithium once in five trials. 

 Apples twice in four trials. 

 Carrots no lithium in two trials. 

 Bread lithium thrice in three trials. 



Cabbage , twice in two trials. 



eight times in ten trials, 

 four times in five trials, 

 six times in six trials. 

 six times in six trials, 

 four times in four trials, 

 eight times in eight trials. 



Tea 



Cotfee 



Port wine 



Sherry 



French wine,, 



Ehine wine 



Ale twice in three trials (traces). 



Porter twice in three trials (traces). 



Mutton, beef, and sheep's kidney showed no 

 lithium : one kidney had a slight trace of lithium. 



I hope in a future paper, with the help of Dr. 

 Dupre, to show that Thallium, Eubidium, and 

 Cassium, by spectrum analysis, can be traced even 

 into the crystalline lens, and to determine the rate 

 at which they pass in, if not out of, the textures ; 

 and by other means we shall endeavour to trace 

 the passage of other crystalloids throughout the 

 textures. 



CONCLUSIONS. 



I. On the Eate of Passage of Solutions of Lithium 

 into the Textures of Animals. 



In guinea-pigs, even in a quarter of an hour after 

 three grains of chloride of lithium are taken into 

 the stomach, the lithium may be found not only in 

 all the vascular textures, but even in the cartilage 

 of the hip-joint, and in the humours of the eye. *If
