These experiments are similar 
to the last, but the specimens were 
taken from a larger tree, and the 
soft wood about the pith, including 
the heart-shake, was allowed to drop 
out. In this case the woody layers 
were placed vertically in the machine 
FIG, 31. for testing them transversely (Fig. 31). 
The mean results of the transverse experiments are 
as follows, viz. :— 
The pieces 1 and 1’, s.g. 543, broke with 05 lbs. E=622720, S=1327
