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 extract 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.
