 Now 



jjy/S-**-jj]/(4 + ^ + 7i).-.*^ 



But we have, from the definitions of p, q, r, 



ay dx 7 



dp dr . 



Thus the term in / becomes 



477 ISI/C^y- 7 '/ 3 ) dx d V dz 



Integrate the last term by parts ; then, if we neglect the sur- 

 face-integral, we have 



and the additional term in the kinetic energy becomes 

 16* 5 Cj i ft[/( W -/3A) + 'g{«h-yf) + h(pf- ag )-\ dxdydz 



The coefficient of p in the last, on substituting for /, g 9 h the 

 values
