    Description: Growth of isolated Phycomyces blakesleeanus sporangiophores was not promoted relative to growth on water either by a synthetic medium with two concentrations of dextrose or by concentrated and dilute potato dextrose solutions. A range of sucrose and dextrose concentrations also failed to promote growth. On the contrary, the more concentrated nutrient media and the pure sugar solutions at 0.08 M and higher reduced the final sporangiophore length measured after 64h. The inhibition on dextrose was directly proportional to concentration up to about 0.7 M and increased more sharply at higher concentration, becoming complete at close to 1 M . At 0.9 M the incidence of branching was greatly increased. Sucrose caused almost the same inhibition as dextrose up to 0.3 M . On complete nutrient media, but not on water, considerable regeneration of mycelium occurred at the sporangiophore base, and the amount regenerated was greater on potato than on synthetic media. Sporangiophore growth was not influenced by the regenerated mycelium. Differences between the submerged regenerated mycelium and surface mycelium are pointed out. Growth of isolated sporangiophores was not affected by pH between 3 and 7.6, but pH 2 caused limited inhibition. The evidence suggests that a factor limiting the growth of the deficient isolated sporangiophores is normally supplied by the mycelium but is not a nutrient or growth factor present in media which support growth of mycelium with sporangiophores.

    Description: The charge‐transfer spectra of MnCl 2 , FeCl 2 , CoCl 2 , and NiCl 2 molecules isolated in argon matrices near 4.2°K have been measured. The results are consistent with the d ‐configuration ground states 6 Σ , 5 Δ , 4 φ , and 3 π deduced in earlier work from gas‐phase Laporte‐forbidden absorption spectra of these molecules.

    Description: An optical cell used in obtaining absorption spectra at temperatures up to 500°C and pressures up to 2100 kg cm −2 is described. The cell can be characterized as a ``null‐pressure'' device. The solution is contained in a sealed quartz cuvette and the pressure exerted by the solution within the cell is balanced by an external pressure of argon gas. The near ir spectra of water below and above the critical temperature are presented.

    Description: This article discusses some major trends in food marketing in the United States, as revealed in a detailed study of food distribution undertaken by the National Commission on Food Marketing. Attention is focused on the growing industrialisation of farming and the consequent decline in terminal auction markets; the increasing role of new product development in ensuring profitability of food processors. Trends in the food retailing industry are also discussed and compared with conditions prevailing in Australia.
