3. Shorea robusta. Transverse series. The individual curves show the inclination of the grain at the 

 successive rin^s along the different sticks. The number against each curve gives the angle between 

 that stick and stick A. In each curve degrees right-handed inclination plotted above the base line 

 and degrees left-handed inclination below. Scale: rings plotted to a scale of 2 cm to 1, and inclination 

 of the grain 1 mm. to 1 degree.
