 continue the lecture and the discussion on it on the following Tuesday (27th 

 June). Another large audience met on the latter date and heard the con- 

 clusion of the address. 



The address dealt fully with the whole subject under the following heads : (1) His- 

 torical outline, dealing with methods of manufacture from earlier times up to the present 

 day ; (2) physical tests ; (3) theories of hardening, showing the existing diversity oi 

 opinion between the highest authorities. [A full report was published in the Otago
