[page 63] Kalle concluded that dissolved yellow substances contribute substantially to any deviation from the blue colour of pure water into the longer wavelengths region of the visible spectrum. […] Chemically the material defied unequivocal characterization, a situation which has remained essentially unchanged. Thus, for want of a systematic designation Kalle called the material Gelbstoff, the German word for yellow material. […] Marine Gelbstoff is a material formed in the sea wit certain spectral characteristics. It is not derived from terrestrial sources and appears to be composed of fulvic and humic components both of which are structrally different from their terrestrial counterparts. […] [page 67] These are more indications of an autochthonous origin of marine Gelbstoff supported by the interesting observation that Gelbstoff from a bog water precipitated within a week at room temperature when an equal amount of seawater was added to its solution.

A general method of studying the Witt group of a smooth variety is through the graded group associated to the filtration induced by the filtration of the Witt group of the function field by powers of the fundamental ideal of even rank forms.

They went to the Six Hickories church—tithed—and behaved themselves.
