tion (16 percent) occurring in physics. Federal 

 funding for the latter field decreased by some 25 

 percent between l'^b8-72. 



In view of the declining research expendi- 

 tures coupled with increased costs of per- 

 forming research and a larger faculty body, some 

 change in the involvement of academic staff in 

 research is inevitable. One aspect of this change 

 is indicated in figure 2o, which presents the 

 funds for applied and basic research per scien- 

 tist and engineer (excluding graduate students) 

 in Ph.D. -granting institutions. (These institu- 

 tions accounted for 9o percent of all academic 

 research in 1972.) The 1972 level of such funds 

 was 15 percent lower than in 1068, in terms of 

 1961 dollars. This reduction is attributable to the

declining level of Federal funding between 1968- 

 72, coupled with the increasing number of scien- 

 tists and engineers in these institutions; Federal 

 research funds per scientist and engineer de- 

 clined by 24 percent during the 1968-72 period, 

 in contrast to the relatively unchanged level of 

 support from non-Federal sources. 



The individual fields were affected somewhat 

 differently by the combined changes in the levels 

 of funding and scientific and engineering man- 

 power, as shown in figure 27. (The fields of
