Abstract
PROF. P. PASQUINI has provided Italian readers with a clear and well-illustrated introduction to modern experimental embryology. He opens with a historical chapter, in which the seventeenth-century controversy between epigenesis and preformation gives him an opportunity to define the fundamental problems. The next chapter, on the maturation of the gametes, gives a good, if elementary, account of the cytoplasmic organisation of the ovum ; but, as so often in embryological works, is old-fashioned in its treatment of meiosis. After these preliminaries, we come on to experimental embryology proper. Although there is nothing very original in the author‘s treatment, he covers the ground adequately, bringing his book right up to date by accounts of such new developments as Holtfreter‘s studies on the mechanism of gastrulation and the various theories of organiser action. The Italians are fortunate in having such a text-book for university students in their early years ; there is nothing similar available in Great Britain.
