    Notes: Synaptosomes incubated in a physiological saline extrude sodium and take up potassium. As would be expected this process is completely blocked by metabolic inhibitors such as cyanide and iodoacetate. However, when metabolic inhibitors are replaced by ouabain (100 μM) there is an increase in the steady state intrasynaptosomal sodium and chloride content even though there is no change in the potassium content. The increases are prevented when synaptosomes are incubated with metabolic inhibitors in addition to ouabain. There is therefore a ouabain-insensitive process that transports sodium, chloride and concomitantly water into synaptosomes. It appears not to function when the supply of metabolic energy is inhibited. The diuretic furosemide (1 mM) in the presence of ouabain inhibits the entry of sodium and chloride without affecting the intrasynaptosomal potassium concentration. Ethacrynic acid (1 mM) has a somewhat similar effect but in addition appears to damage the synaptosome membrane.Kinetic measurements were made of the uptake of sodium, potassium and chloride under conditions of metabolic inhibition and the permeability constants of the membrane determined. Values of 0.068, 0.117 and 0.032 × 10-6 (cm s-1) were found for the permeability constants of the membrane to (respectively) sodium, potassium and chloride. Measurements of the rate of uptake in the presence of ouabain revealed an inwardly directed sodium and chloride flux of 5-20 pmol cm-2 s-1. Calculation of the fluxes from the steady state ion concentrations also reveals an inwardly directed sodium and chloride flux, though of lesser magnitude. The influx of water is less than would be expected to preserve osmotic equality suggesting that the translocation of sodium and chloride is the primary event. Although its function remains uncertain the flux has a considerable effect on the ion content of synaptosomes.

    Notes: With a career that began at the University of Missouri in the early 1880s and culminated at the USDA in the 1930s, Beverly Galloway devoted his life to practical botany and agriculture. He became a driving force in the movement for "New Botany" during a period that stressed an experimental approach as well as new disciplines such as plant pathology. As administrator and scientist, he was arguably the single, most influential figure involved in the early growth and development of plant pathology and the plant sciences generally in the USDA. From assistant mycologist in the Section of Mycology to Chief of the Bureau of Plant Industry to Assistant Secretary of the USDA, Galloway displayed exceptional administrative acumen. His administrative and scientific skills were instrumental in laying the foundations for the science of plant pathology during its formative period in the United States.

    Notes: The problem of suffering is essentially a problem in philosophical theology. For many philosophical systems the phenomena of suffering set no special problem at all. The most influential philosophies of the present age, for example, have almost nothing to say on the subject—and there is no reason why, on their metaphysical; principles, they should say anything. The problem is a relevant one only for those philosophies which claim to be in at least general accord with the “religious interpretation of the universe.” But for them it is crucial. Given a Weltanschauung like that of Absolute Idealism, for which the ultimate principle from which all things derive their being is an Infinite and Perfect Spirit, and it becomes at once a clear obligation to offer some explanation of how we are to reconcile the Goodness of God with the existence in the world of so much suffering which is prima facie just bad. As we all know, the problem is an extraordinarily hard one to solve. But, inasmuch as the religious interpretation of the universe demands its solution as a condition of its own possibility, its importance is proportionate to its difficulty.
