This small book is largely a review and summary of Professor Lopashov's various publications and those of his colleagues dealing with experiments on embryonic eyes of amphibians. It is an attempt to throw light on some general problems of causality in development. It embraces the results of studies chiefly on species of three urodeles and five anurans in which the embryonic eye at different early stages in development are placed in various environments such as the brain cavity, body cavity, and saline solution. The eye was implanted or explanted either with or without the lens and surrounding mesenchyme.
The varying embryonic ages in the status of the experimental eye and the sometimes different results from different species of eyes provide the complicated background out of which Professor Lopashov makes his conclusions. Often there is much detail and repetition which makes slow progress for the reader. However, there are special headings
