Iron.—In Man, Peters found evidence of- the presence of red blood corpuscles in the trophoblast of the early ovum, and Ulesco-Stroganowa ^ states that they are also present in the syncytium in later stages. This has been disputed by Kworostansky ^ and Hofbauer, who maintain that the corpuscles are first dissolved. More recently Bryce and Teacher found no evidence of the ingestion of red blood corpuscles by the tropho- blast, while Bonnet* has shown that the syncytium gives the eosin- ' Hofbauer, Qrundziige einer Biologie der menschlichen Plazenta, Leipzig, 1905. ^ Ulesco-Stroganowa, " Beitrage zur Lehre vom mikrbskopischen Bau der Placenta," Monatsschr. f.
