Absorption of Nickel and Cobalt. 



163 



Both animals were found dead on the 9th, In the cobalt rabbit, 

 the stomach, lungs, kidneys and brain were found more or less 

 congested and there was considerable diarrhoea before death. In the 

 nickel rabbit, there was no diarrhoea and but little congestion. Rec- 

 tum was found full of hard faeces. 



Following is the distribution of the poison in the two rabbits.

Very noticeable in both of these results, as in the preceding ex- 

 periments, is the comparatively large amount of poison in the brain 

 and spinal cord, also the same relative distribution in the muscle 

 tissue of the legs and back previously commented upon. The large 

 amount of j^oison in the lungs and heart, as contrasted with the liver 

 and kidneys, is also quite noticeable.
