300 TIMBER AND TIMBER TREES. [CHAP. 



Relatively considered, they stand as follows, viz. : 



TRANSVERSE STRENGTH. 



a = '86 

 b = -97 



C = I '00 



d= 93 



TENSILE STRENGTH. 



a = '88 

 b = '88 

 c = i 'oo 

 d= 78 



The specimens referred to in Table CLX., after 

 being prepared for the experiments, lost 9 per cent, of 

 their weight in the twenty days prior to breaking them, 

 and seemed then to be in good-seasoned condition for

A further series of experiments were made in a 

 somewhat similar manner to that adopted with the
