To watch a curious young macaque explore and manipulate his immediate surroundings must surely delight and amaze us all. The monkey selects a particular objectfor scrutiny, reaches out and grasps it, handles it delicately with the fingers or more forcibly with the hand, scans the various surfaces with the fin ger pads, and finally identifies it. If we compare this monkey's adroitness and discriminative capacities with our own, at once we have a concise statement of important biological similarities and differences among primates. While there are species diffe rences in the functional anatomy of the hand, in tactile sensibi lity, and in the control of hand movements, these are relatively minor. The real difference in the dexterity of the two species relates to the complexity of the task that is executed: no monkey, and for that matter only one man in a century, paints a Guernica, although an astute investigator can readily teach the monkey to flourish a brush and paint a few strokes. The goal of the symposium, of which this book is a summary, was to examine current knowledge of those cortical mecha nisms that determine the sensorimotor functions of the hand that are common to man and the monkey - mechanisms accessible to analysis by recording the responses of single cortical neurons while the monkey explores and manipulates his surroundings."

The overall scope of this new series will be to evolve an understanding of the genetic basis of (1) how early mesoderm commits to cells of a heart lineage that progressively and irreversibly assemble into a segmented, primary heart tube that can be remodeled into a four-chambered organ, and (2) how blood vessels are derived and assembled both in the heart and in the body. Our central aim is to establish a four-dimensional, spatiotemporal foundation for the heart and blood vessels that can be genetically dissected for function and mechanism. Since Robert DeHaan's seminal chapter "Morphogenesis of the Vertebrate Heart" published in Organogenesis (Holt Rinehart & Winston, NY) in 1965, there have been surprisingly few books devoted to the subject of cardiovascular morpho genesis, despite the enormous growth of interest that occurred nationally and inter nationally. Most writings on the subject have been scholarly compilations of the proceedings of major national or international symposia or multi authored volumes, without a specific theme. What is missing are the unifying concepts that can often make sense out of a burgeoning database of facts. The Editorial Board of this new series believes the time has come for a book series dedicated to cardiovascular mor not only as an important archival and didactic reference phogenesis that will serve source for those who have recently come into the field but also as a guide to the evo lution of a field that is clearly coming of age.

A. W. Livingston (1821-98) was a Reynoldsburg, Ohio, tomato seedsman who was the best known developer of tomato varieties in the United States in the nineteenth century. First published in 1893, Livingston and the Tomato contains both descriptions and drawings of the tomato varieties he developed. Livingston discusses his methods and results and how to respond to tomato diseases and pests. In addition, the book features over sixty tomato recipes, including ones for slicing, frying, escalloping, baking, and broiling tomatoes; as well as for tomato toast, custard, soup, pie, preserves, figs, jam, butter, salad, sauce, and omelets.

Studies of the perception and transduction of hormonal signals in higher plants are relatively recent. Despite the rather small number of researchers involved in comparison, say, to those studying signalling in animals, plant scientists are becoming attracted to this important field because of the fascinating mechanisms being revealed and the recognition that any hope of understanding the ways in which the growth and development of the whole plant are controlled can only be based on an exploration of the physiology, biochemistry and molecular biology of these mechanisms. The Moscow symposium that gave rise to the present book drew many of the most active workers in the area, and many new developments were revealed. Audience: Important reading for all those interested in plant growth and development.
