tensity at successive points, there is an infinite number of re- 

 sultant lines of maximum tensile and compressive stress passing 

 through each transverse section of the femur. As it is desired 

 to know the paths of only a few of these resultant lines of stress,

Fig. 19 Diagram of the lines of stress in the upper femur, based upon the 

 mathematical analysis of the right femur. These result from the combination 

 of the different kinds of stress at each point in the femur, which figure 18 a shows 

 in detail for section 8.
