Erratum

On page 518 of the recent article by Frederic E. Holmes (Closed-system apparatus for aeration-diffusion: Application to determination of blood ammonia. Clin. Chem. 10, 512 [1965]), a line of type was inadvertently dropped. The final sentences of the next-to-the-last paragraph should read as follows:

A possible explanation is that in a thick film more gas diffuses to-and-fro within the liquid, but in a thin film only a small amount can diffuse through the liquid in the very narrow cross area presented to it. Consequently a larger proportion is forced to diffuse across the interface into the space above the thin film.
