The Authors have investigated by means of the immuno-electrophoretic method the protein composition of the funicular blood of 19 twin-pairs from pregnancies of 5 to 9 months. Monochorionic twins showed a concordant picture, while in 7 of the 14 bichorionic twin-pairs slight differences could be observed, due to the presence in one of the twins of one or two more lines. The Authors put these results in correlation with the hypothesis of a genie control of the production of proteins.
