An unusual mode of distribution of low‐molecular‐weight n‐alkanes (C 11 ‐C 15 ) with a slight even carbon‐number predominance has been observed in the gas Chromatographic analysis of the paraffin fraction which was extracted from the wool of live sheep. This is in addition to the other two modes of medium‐, C 15 ‐C 24 , and high‐, C 24 ‐C 33 , molecular‐weight alkanes usually present in wool wax which have also been found in sheep's manure. The high‐molecular‐weight hydrocarbons (predominantly odd carbon‐numbered) are presumed to be derived from the diet (pasture plants) whereas the other two hydrocarbon distributions probably result from the combined action of animal and microbial metabolism.
