This is an appeal from a judgment of the District Court for the Eastern District of Pennsylvania quashing a return of service on a summons. The summons was served upon Chase Brass and Copper Company, Inc., a wholly owned subsid *947 iary of Kennecott Copper Corporation. It is claimed that service on the subsidiary is, under the circumstances of this ease, effective service upon the parent corporation.

The case was thoughtfully considered by the district judge. He set out the pertinent facts as they appeared from the record and he discussed the law involved. The opinion, happily brief, covers the points adequately. 21 F.R.D. 222.

The judgment will be affirmed.
