1481. DOUGLAS, J. C. The cry of tin. 



Mg. Sci. Press, Vol. 43, 1881, San Francisco, p. 99. 



The sound emitted by tin when bent, is not peculiar to tin and can be imitated 

 with other metals of a crystalline structure. Heated rolled zinc emits a " cry " like 

 tin, only fainter. Cast zinc, if pinched between the .teeth or plier emits the sound 

 distinctly. This cry, alone or in conjunction with a microphone, becomes an indicator 

 of the crystalline texture of metal beams and their fitness for certain classes of work.
