We do not consider the defendant’s claim concerning the alleged exclusion of “paupers” from the grand jury which indicted him on May 8, 1972, because the defendant made no attempt to prove any such exclusion as matter of fact. See Commonwealth v. Stone, 366 Mass. 506, 509-510 (1974), and cases cited. We do not consider the sufficiency of the evidence to convict on either indictment because no such question was raised below.

Exceptions overruled.
