To quickly assess the difficulty of the text, read a short excerpt:
An aliquot portion of the filtrate was titrated with standard alkali. The total extracted material and ash were determined in another portion of the filtrate. The muci- laginous material was precipitated from a fresh portion of the aqueous solution. The nitrate from the mucilaginous material strongly reduced Fehling's solution, indicating, therefore, according to Dragendorff, the presence of glucoses, acids, and extractives. A portion of the residue obtained by evaporation of the aqueous extrac...t to dryness was also given to a cat, and, as before, no evident ill effects were produced. The dilute alkali and dilute acid extracts were obtained by succes- sively extracting the plant material with 200 cc of the cold menstruum in each case. After the dilute acid extraction the material remaining was dried and weighed. From the results of the physiological tests given in the previous paragraphs, it may be concluded that Tecoma mollis contains no con- stituents capable of powerful action, and it also appears probable that the plant contains no ingredient of exceptional medicinal virtue.
