The purpose of this book is twofold: it is meant to serve both as a practical manual for the study of animal development and as a general introduction to the subject. Central to our en deavour is the belief that developmental biology is best taught

The meaning of some terms used in describing the development of embryos is discussed in the light of their historical origin and current usage. Attention is focused on the terminology associated with the early development of animals, particularly tha

The ultrastructure of the mitochondrial cloud (Balbiani body) of the pre-vitellogenic oocytes of Xenopus laevis has been examined using transmission and stereoscan electron microscopy. Examination of conventional thin sections confirm previous observ

An estimate has been made of the numbers of mitochondria in the mitochondrial cloud (Balbiani body) of Xenopus laevis oocytes ranging in size from 50 to 250 μm. The mito-chondrial number is expressed in terms of a ‘standard’ organelle measuring

A stereoscan electron microscope has been used to survey the epidermis of axolotl embryos as it becomes ciliated. The observations are consistent with much earlier ones that ciliated cells first occur on the surface of the epidermis at about the time
