  Let I be an ideal of a Complete Cohen-Macaulay local ring R of dimension n.
We wil show that the natural homomorphism Rto HomR(HcI(KR), HcI(KR)) is an
isomorphism provided that I is a cohomologically compltete intersection ideal
of grade c where KR (resp. HiI(.)) denote the canonical module (resp. i-th
local cohomology with respect to the ideal I) of R. The same result is true for
the Matlis dual of HcI(KR).
