SUMMARY Permethylation has been applied to the polysaccharide in soil, which has been oxidized with 0.2 m NaIO 4 and treated with 0.1 m Na 2 B 4 O 7 . The amounts and types of methylated sugar obtained on hydrolysis have been compared with those from unoxidized soil. As well as a number of derivatives corresponding to 1 ‐3 linked glucose, arabinose and xylose, considerable proportions of 1‐4 linked glucose and xylose also persisted. The polysaccharides appear to persist for both chemical and physical reasons.
