Factors Influencing Myocardial Contractility

and water balance in insect eggs, ion and water transport across epithelia and the physiology of reproduction. This is an excellent volume, well edited and well documented with references useful to a wide range of basic biological scientists. The contributors have two things in common: they have accepted the eminent suitability of insects as vehicles to elucidate principles in cellular physiology and have shared, for varying periods of time, an association with Sir Vincent B. Wigglesworth who pioneered in the field of insect physiology at Cambridge.
