It is evident that the agreement between calculated and observed 

 results is excellent; such divergences as found at the sections 1.0 and 

 5.0 Ken from the tip is evidently due to an irregularity in the sectional 

 form. Nevertheless, the agreement between theory and observation is 

 highly satisfactory throughout and of such a nature as to justify the 

 conclusion that in all probability the hypotheses from which the theoreti- 

 cal relations were deduced are essentially correct. 



Again calculating the " form-quotient " with respect to the breast- 

 height radius, we obtain the following tables:
