title: Tubal pregnancy: a report of a very early luminal form of imbedding.
abstract: A specimen of a very early ovum, 4 to 6 days old, shown in the luminal form of imbedding before any hemorrhage has taken place, confirms that the luminal form of imbedding does occur. This case probably represents the earliest tubal pregnancy reported.
