Industrial waste waters are often discharged into rivers in which the concentration of dissolved oxygen varies considerably, and it is therefore important to know how this will affect the toxicity to fish of poisons that may be present. In 1933, South-gate, Pentelow & Bassindale found that when fish were placed in a fixed volume o
