From the tabulated data of these experiments, several deduc- 

 tions become seif evident. Aluminium did not accumulate in the 

 blood, but some of the tissues showed marked tendencies to accumu- 

 lation. Aluminium seems to be abundantly excreted in the bile, 

 as the results of the first and second experiments show with special 

 emphasis. 



That the aluminium in these tissues cannot be regarded as aris- 

 ing from residual blood is evident from the analytic data. The 

 animals were very thoroughly exsanguinated, and the proportion of 

 residual blood in any tissue was negligible.
