296 Strehlke on the Acoustic Figures of Plates. 



by which it appears that the elasticity of the one-half of the 

 plate slightly differed from that of the other. 



In another brass plate (No. 2.) of 34"'-3 length, and 0"'-66 

 thick, tHe equation for the branch B of the hyperbola was 



2/ 2 = 1-1421 . x . + 6'"- 126) .... (1) 

 and that for A 



7/ 8 = 1-1472 . a . + 6"'-062) (2) 



which shows that the elasticity in both halves was almost 

 equal. 



The difference between measurement and calculation appears 

 from the following tables :
