Abstract
This paper deals with some special cases on Hasse's principle about the diagonalization of Z-lattices L of indefinite regular guadratic forms over Q. It is asserted that for some specific values of a certain set D of discriminants of L, that the local condition of Lz diagonalization is equivalent to the global condition that L is an odd lattice.
