volumetrii estimal of hydroxylamine, by M. M. L. |. Simon. 



Hydroxylamine oxalate can be titrated with potassium perman

exacl method for the titration of any salt of hydroxylamine can 

 be based upon this fact. On the method ol manufacture of aims 

 of the bronze period, by M. F. Oemond. Hy the application 

 of the methods Ol micrographic analysis to specimens of ancient 

 bronze implements, it has been found possible to trace differences 



in the i le of manufacture, and il is regarded as possible thai 



a methodical study on these lines may lead to the classification 

 of bronze implements with regard to time. -On the composition
