Remarks.—The whole of these broke with a moderate jength of fracture and splintery. 
The above-mentidned specimens were all of good 
quality, well seasoned, and taken from trees of 6 to 8 
feet in circumference. It will be observed that the 
specific gravity and breaking strains varied only in a 
slight degree. By the formule— 
E = 309240. S = 1645. 
Experiments were also made to test 
the transverse strength of a series of yO 
seven pieces (Table CXLIX.) cut from [7777 
a plank 2 inches thick, taken out of the 
middle or centre part of the butt-end 
of a tree, the centre piece © being 
made to include the pith (Fig. 30).
