L XV. Experimcjits on the Modulus of Torsion. By Benjamin 

 Bevan, Esq.* 



NUMEROUS experiments have already been published 

 on the strength of wood and other substances, as far as 

 regards their cohesion and elasticity ; but I ain not aware of 

 any extensive table of the modulus of torsion of dilferent spe- 

 cies of wood, deduced iVom expqriments conducted upon a 

 proper scale, and with the necessary care.
