We are grateful to Dr Robert A. Goldstone of Paterson, New Jersey, for pointing out an error in the article by M. R. Colwill and R. H. Maudsley on "The Management of Gas Gangrene with Hyperbaric Oxygen Therapy" in this Journal of November 1968, 50-B, 732. On page 742, the second line should read "They recommend the use of/ow molecular weight dextran (dextran 40, Rheomacrodex) to prevent the sludging and thrombosis that also occur . . ." The correction is important because high molecular weight dextran (dextran 70, Macrodex) would not be expected to have the desired effect.

1. The management of gas gangrene by hyperbaric oxygen is described.

2. The mode of action, administration and risks of hyperbaric oxygen are discussed.

3. A series of seventeen cases, with one death, is recorded from a hospital unit with a small chamber, using two atmospheres in pure oxygen.
