Summary

A transplant consisting of the rudiment of a cloaca with some somatic material implanted at a certain distance ventral from the normal route taken by the pronephric duct can be the cause of a deviation of the duct from its normal course. The pronephric duct grows towards the secondary protodæum, whereas the duct is lacking in the part of the body behind the secondary proctodæum. It seems that the proctodæum exercises an attractive effect on the growing pronephric duct.

The results of the experiments, at any rate, are in favour of the conception ofO'Connor (1938) andVan Geertruyden (1942), who found that the pronephric duct develops by its own independent growth. I cannot agree withVan Deth's opinion (1946), according to which the pronephric duct developsin situ out of the dorsal parts of the lateral plate.
