Transcriber's Notes: The original spelling and minor inconsistencies in the spelling and formatting have been maintained. The following words have been variably hyphenated in the original: oxy(-)cumarin, tri(-)saccharides, sugar(-)like, mono(-)saccharides, sea(-)weeds, di(-)sodium, foam(-)like, di(-)basic, aldo(-)hexoses, chromo(-)proteins, galacto(-)octose, gluco(-)octose, keto(-)hexoses, ligno(-)celluloses, manno(-)octose, para(-)pectic, di(-)saccharides, poly(-)saccharides. The variable hyphenation has been retained in this version. Formatting: Text in italics was marked using underscores (_text_) and bold text using equals (=text=). The greek characters alpha and beta were marked as [alpha] and [beta] Triple bonds were marked as [trb] in order to keep the lt1-text. On page 120 the illustration of the decomposition of chlorophyll a and chlorophyll b could not be displayed due to its complex structure. On page 147 the incorrect formulas of sitosterol, C_{27}H_{43}OH and stigmasterol, C_{30}H_{49}OH were not changed due to the fact that the pure compounds were first isolated in 1926 after this book was published. The table below lists all corrections applied to the original text.
