    Notizen: [Auszug] WE, Wager in St. Kilda and a little later Bailey at Slieve Gullion, have recently been led, quite independently, to a novel conclusion concerning local inter-relations of certain basic and acid igneous rocks belonging to the British Tertiary province. Evidence from opposite ends of the province, ...

    Notizen: [Auszug] I have fed measured numbers of spores of Nosema apis to individual bees and watched the progress of infection under various conditions of treatment by sampling bees daily and counting the ventricular content of spores by means of a hsemocytometer. Group of individually infected bees (fed 1,000,000 ...

    Beschreibung: 1. The effect on cow health of galactopoietic stimulation with thyroactive materials was determined from a statistical study of the results of a large field experiment involving 2000 cows over a 3-year period.2. The same experimental procedure was followed on thirty-seven farms scattered over England, Scotland and Wales. This procedure was planned to ensure that half the cows in each herd would receive a course of treatment with iodinated casein or thyroxine, and that the other half would constitute a suitable set of controls. Cows that remained in the herds received second and third treatments in successive lactations.3. The galactopoietic stimulation was started at a fixed interval after calving, irrespective of the season of the year.4. The use of the thyroactive materials in successive lactations did not have any serious adverse effects on the health of cows. The effect on productivity was less than had been expected, since the increase in milk yield resulting during the period of hormonal treatment was often largely or completely negatived by a shortening of the lactation period.5. The incidence of disease was somewhat greater in the treated than the control group, the principal contribution to this difference being from the diseases described as digestive disorders. There were some other differences of lesser significance.6. The rate of disposal of treated and control groups was almost identical.7. There were no adverse effects on the reproductive life of treated cows; factors studied were the efficiency of coitus, interval between parturitions, length of gestation and incidence of abnormalities at parturition.

    Beschreibung: As is well known the northern face of Garbh Bheinn, which rises from Loch Leven east of Caolasnacon farm, is occupied by a “very obvious asymmetric downfold” of inversion Eilde Quartzite (Hardie, 1952, p. 273; Bailey, 1934, p. 485). The inversion is established by current bedding and is unquestioned. The Eilde Quartzite here floats on Eilde Schist, younger than itself. The occurrence marks the western end of the Kinlochleven Inversion, one of the most remarkable geological structures known to science.
