TIMBER AND TIMBER TREES. [chap. 
Relatively considered, they stand as follows, viz.:— 
TRANSVERSE STRENGTH. 
a = ’86 
b = -97 
C — I'OO 
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 
use. 
A further series of experiments were made in a 
somewhat similar manner to that adopted with the
