Solar Wind Electric Fields in the Ion Cyclotron Frequency Range

Measurements of fluctuations of electric fields in the frequency range from a fraction of one Hz to 12.5 Hz are presented, and corrected for the Lorentz transformation of magnetic fluctuations to give the electric fields in the plasma frame. The electric fields are large enough to provide the dominant force on the ions of the solar wind in the region near the ion cyclotron frequency of protons, larger than the force due to magnetic fluctuations. They provide sufficient velocity space diffusion or heating to counteract conservation of magnetic moment in the expanding solar wind to maintain nearly isotropic velocity distributions

Native Dye-Plants and Tan-Plants of Iowa, with Notes on a Few Other Species

In early days, dyers depended almost entirely upon the vegetable kingdom as the source of their supply of coloring materials, the most important exceptions being sepia from a species of cuttle fish and Tyrian purple from the Murex. Feral plants were the chief reliance but the uncertainty of obtaining a sufficient amount of the raw material, as well as the inferior quality of much of that brought to the market together with the development of the science of organic chemistry led to the replacing of natural dyes with synthetic or artificial dyes

The Flora of the Rainy River Region

There is no evidence accessible to the writer that a critical study of the flora of this region has ever been made, although several of the early explorers must have passed over this part of Minnesota
