The luteal tissue is vascularised and the central cavity filled in with connective tissue. the present writer issued a prehminary account ^ of an experi- mental inquiry upon the formation of the corpus luteum in the sheep. In this inquiry the animals were killed at successive intervals after coition, or (in cases where coition did not or was not known to occur) after CEstrus was observed. The result of this investigation was to confirm BischofE's hypothesis in all 1 Marshall, "Preliminary Communication on the CEstrous Cycle and the Formation of the Corpus Luteum in the Sheep," Proc.
