 gen in relation to rice soils. Mem. Dept. Agric. India Chem. Ser.5: 181-194. 1920. — Carbon 

 dioxide and H do not exist in association in paddy rice soils. Carbon dioxide is apparently 

 reduced by H as fast as .t is formed, resulting in the formation of marsh gas and organic 

 matter. This reaction is said to be an important factor in the conservation of the oxygen, 

 which remains available for root aeration. — J. J. Skinner.

1073. Britton, N. L. Investigations of the flora of northern South America. Science 

 53: 29. 1921. — In 1918 a cooperative effort was made by the New York Botanical Garden, 

 the United States National Museum, and the Gray Herbarium to investigate the botany and 

 plant products of northern South America. The investigation has made good progress 

 through the study of specimens already obtained in Dutch and British Guiana, Trinidad, 

 Tobago, Venezuela, Curagao, Colombia, and Ecuador. This undertaking has been furthered 

 by the heartiest cooperation on the part of leading men in the countries concerned. A wealth 

 of material hitherto unknown to science has already been identified, and many facts are being 

 added to our knowledge of the flora and its geographic distribution. — A. H. Chivers.
