The International Biological Programme (IBP) was a cooperative effort on the part of scientists throughout the world, whose goal was an integrated study of the basic processes of biological productivity.

There are few achievements of modern man which can compare to the Suez Canal.

The scanning electron microscope (SEM) has been used with increasing frequency in recent years to study the surface mor- phology of normal, transformed and malignant leukocytes.

Agrometeorology is a comparatively young science.

The acid metabolism of certain succulent plants, now known as Crassulacean Acid Metabolism (CAM) has fascinated plant physiologists and biochemists for the last one and a half centuries.

Dynamic Morphology is the attempt to correlate surface architec- ture and shape of fixed cells, as visualized by scanning electron microscopy (SEM), with the behavior of living cells, recorded by microcinematography (MCM).

The establishment of the morphologically and physiologically intimate contact be- tween two genetically different individuals, mother and embryo, which takes place during implantation, has always exerted a fascination on researchers in biology and medicine.

One aim of the physical sciences has been to give an exact picture of the material world.

Cytological techniques have greatly improved in the last twenty years, largely as a result of further development of the microscope.

A considerable amount of information on the retinal morphology in fishes has been accumulating during the past century.

Scientific investigation of the retina began with extensive studies of its anatomical structure.

The problems associated with the movement of water and solutes throughout the plant body have intrigued students of plants since Malpighi's conclusions in 1675 and 1679 that nutrient sap flows upward and downward in stems through vessels in both wood and bark.

One of the points clearly stressed in the beginning of this book is that the essential feature of any dynamic system is change and that, where there is change, there may also be growth and evolution.
