This is a petition for a writ of error. The defendant in error filed a general demurrer. The single justice sustained that demurrer and ordered the judgment affirmed. Rule 30 of the Supreme Judicial Court for the Regulation of Practice at Common Law (1926), 252 Mass. 598. The plaintiff in error undertook to appeal to the full court. It has long been established that appeal does not lie from a decision of a single justice of the Supreme Judicial Court in a proceeding at law. That procedure is confined to appropriate cases in the Superior and some other courts. The proper method of seeking review by the full court of a decision or ruling by a single justice in an action at law, if not reported by him, is by a bill of exceptions. G. L.

Appeal dismissed.
