POLYGRAMIST CONVICTED. George Reynolds was found guilty of bigamy or polygamy at the last term of the District Court, under the United States law of 1872 punishing bigamy in the Territories. This being the first conviction in this Territory under that law, Reynolds was not sentenced. A writ of appeal was taken to the Supreme Court, with the intention of taking the case to the United States Supreme Court. The Supreme Court of the Territory decided to-day that the previous conviction was null and void from the fact that the grand jury was composed of twenty-three instead of fifteen grand jurors, as required by the Terri-torial statute.
