It has been found that humic acids in aqueous solution, as previously found with their sodium salts, behave as linear polyelectrolytes.
A possible explanation in terms of intermolecular associative forces is suggested.

## Abstract Hyaluronic acid (HA) is a naturally occurring polysaccharide with unique biomedical applications. We have studied the cohesive and rheological properties of HA of three molecular weights (0.35 Γ 10^6^ β1.80 Γ 10^6^ Da) and found that the cohesive nature of HA was highly dependent on mol
The ultimate analyses, u.v.-visible absorption spectra, fluorescence spectra and i.r. spectra of five humic acids have been studied. One was obtained commercially from peat, two from organic-rich soils, one from an estuary and one from a marine sediment. The U.V. spectra were used to compare average
results were interpreted in terms of an oxygen transfer mechanism involving oxidation and reduction of a copper-cupric oxide system. ## 108. Oxidation of graphite powder in carbon dioxide oxygen and air K. Seibold (Lonza Ltd., Sins, Switzerland). Oxidation of graphitized coke and anthracite in COZ
