    Notes: Abstract This paper describes a field study to assess the effect of increasing the frequency of split applications of N fertiliser on the pattern of plant uptake, soil N availability, and microbial biomass C and N. Measurements were taken during the growing season in different positions relative to young trees (Prunus avium L.) in an upland silvopastoral system in its first year after establishment. At fertiliser rates of 72 and 144 kg ha-1 N applied as NH4NO3, increasing the number of split applications increased N uptake by the pasture. Mineral forms of soil N measured 2 weeks after application indicated that residual NH inf4 sup+ -N and total mineral N were also greater in this treatment on certain dates. Soil NO inf3 sup- -N was positively correlated with the soil moisture content, and nitrification reached a maximum in early May and declined rapidly thereafter except within the herbicide-treated areas around the trees where soil moisture had been conserved. Results of the study suggest that high NO inf3 sup- -N in herbicide-treated areas was probably caused by mineralisation of grass residues and low uptake by the tree rather than by preferential urine excretion by sheep sheltering beside the trees. Mean microbial biomass C and N values of 894 and 213 kg ha-1, respectively, were obtained. Microbial C was slightly increased by the higher frequency of split applications at 144 kg ha-1 N and was probably related to the greater herbage production with this treatment. Microbial N was not significantly affected by the N treatments. Both microbial biomass C and N increased during the growing season, resulting in the net immobilisation of at least 45 kg ha-1 N which was later released during the autumn.

    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: A case of tinea nigra occurring in a Caucasoid girl aged 10 is described. The infection was probably contracted in Malaya where she had lived between the ages of 2 and 4½. The course of the infection was chronic and protracted, with a tendency to recur after apparent cure. The mycological features are described and the aetiology is discussed.

    Notes: Summary Mice treated with divinyl ether-maleic anhydride (DVE/MA) 7 days before, 2 days before, or simultaneously with foot-and-mouth disease (FMD) viral antigens (aqueous or oil emulsified) were more resistant to virus infection and released antibody earlier than mice treated with antigen alone. Simultaneous treatment of swine with these antigens plus DVE/MA resulted in a slightly enhanced early antibody response, which, in a test with oil-emulsified antigen, was not associated with an early induced antiviral resistance to FMD. In general, the primary and secondary antibody responses to oil antigen plus DVE/MA were the same as in control swine receiving the antigen alone. However, swine sensitized with aqueous antigen plus DVE/MA responded faster and developed higher antibody titers after a secondary treatment with aqueous antigen than swine treated similarly but without DVE/MA.

    Notes: Summary The mechanism of resistance to foot-and-mouth disease virus (FMDV) which occurs 2 days after divinyl ether-maleic only anhydride (pyran copolymer) treatment but diminishes by the 7th day was investigated. Adsorption of virus by minced infant mouse spleen, muscle, kidney, heart or liver was not affected either at 2 days or 7 days after treatment of the mice with pyran. However,in vitro multiplication of FMDV in minced kidney was affected by pyran at both times. The resistance of mice 2 days after treatment was related to absence of virus in muscle, kidney, and spleen tissues. Seven days after pyran administration, however, FMDV was recovered from muscle and spleen but not kidney. Interferon was recovered from various tissues 2 days but not 7 days after mice were injected with pyran. Other unknown polymer-induced antiviral factors as well as interferon may have been related to the resistance mechanism.
