Extract

For two years, from June, 1927, the writer held a Research Scholarship in Sanitary Science from the Grocers' Company, the terms of reference including a biological study of the fauna of sewage-treatment plants. Special attention was paid to the free-living nematodes since in mere quantity they form an important section of the fauna in many treatment units, and they have been much neglected as a group in comparison with the protozoa and bacteria.
