This is a most important volume resulting from an intensive psychiatric study made at the Yale Clinic of Child Development. The embryologist and anthropologist have long been making scientific studies of physical growth from birth to maturity. Medicine has long needed scientific studies correlating physical growth with behavior growth. In this volume, as well as in a number of other works produ...

of the conventional kind; one can make operations on the developing wings, using fine glass needles and the other micro-surgical instruments of experimental embryology. A considerable series of such operations has been made by Lees 6 who was able to confirm, and in some cases to extend, many of the previous deductions. For this particular organ there remains very little of that gap between gene...

In spite of sophisticated development in assisted reproductive techniques (ART) in the past three decades from birth of the first IVF baby, Louise Brown, in 1978, and increase in the success rate of infertility treatment up to 50%–60% in well-designed centers using standard protocols and intensive total quality management , these treatments face a few difficulties including multiple pregnancy a...

An understanding of the physiological and structural development of an embryo requires a knowledge of the precise state that development has reached. Without this knowledge it is not possible to compare findings from experiments performed on different embryos or to relate them to structural changes during development. In previous work on Acridid embryos two methods have been used in estimating ...

HE events that take place in the development of the mammalian T embryo have not been subjected to an extensive causal analysis so far. The reasons for this are“to be found mainly in the lack of suitable methods. It is not possible yet to use transplantation, isolation or vital staining techniques on mammalian embryos as they have been used on amphibian embryos. In the course of time it probably...
