Several of the pressed specimens were sketched to scale for permanent record. The fresh weights of the samples were recorded immediately following the collection, after which the material was dried in an electric oven, with circulating air, at a temperature of 70° C. When thoroughly dry, the samples were finely ground, bottled, and tightly stoppered. After the analyses of the samples were completed an aliquot part of each sample was dried at 100° C to constant weight; the analytical data were then ex- pressed on this moisture-free Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Gordon, Aaron, 1894-1975; Sampson, Arthur W.
