Schauta regards the cysts found in connection with sometorsions as insufficient proof of their ante-mortem occurrence. Tor-sions are more frequently present in the umbilical cords of male thanin those of female foetuses, and are sometimes surprisingly reports a case in which he observed three hundred and eightyrotations of the cord on its longitudinal axis.
