length taking 174 tons to crush it ; and finally, there 

 were other pieces 9 x g)^, varying by 3 to 6 inches from 

 12 to 30 inches in length, the strongest of which, 21 inches 

 in length, took 368"6 tons to cripple it ; the details 

 of these will, however, appear in Tables LXII. and 

 LXIII. 



The following experiments were made in order to 

 test the deflections of Teak under given weights at 

 various distances, viz : — 



Table LVIII. 



Nos. I to 6. 



The specific gravity of these pieces was respectively 

 ■586 and "631 ; a proof that they were: Iftiproughly 

 seasoned. Upon the laws which govern these-deflections, 

 I offer no opinion, and the experiments are merely in- 

 troduced here to show how near the results go to confirm
