✦ Synopsis

Water exchange has been studied in ovarian and body cavity eggs of three Anuran species ( R a m esculenta, R. pipiens and R. temporaria) with the isotope exchange method using the automatically recording diver balance. In order to estimate the rate of water diffusion in egg cytoplasm (D), a factor required to determine the rate of water permeation (= the exchange coefficient, E), three different chemical treatments (digitonin, ethanol and formaldehyde) have been used to remove the

## Abstract In contrast to previously published observations of constant daily water loss during incubation in some large, precocial eggs, daily rates of water loss increase approximately 42% between days 1–4 in redwinged blackbird eggs and conductance to water vapor increases 47 and 48% during the
