Ozone soundings at the
French Antarctic Base Dumont d'Urville, 1958;
before the use of Chlorofluorocarbons.
The following copy of a 1990 Letter to the Editor of "Annales Geophysicae" by P. Rigaud and B. Leroy was faxed to me in 1993, saved on thermal fax paper and unfortunately the image quality has deteriorated, particularly on the Comment by D. de Muer which is page 4. I do not know if there were more pages to the Comment.

Comment by D. de Muer
Peter (in October 2005) has sent in the following comment, quoting
from the abstract of Paul Newman's paper (not to be confused with the
Hollywood actor of the same name!) in Science, vol. 294, 1994,
pages 543-7 ("Antarctic total ozone in 1958").
"These [Antarctic Dumont d'Urville] measurements were derived from spectrographic plates of the blue sky, the moon, and two stars. These Dumont plate data are inconsistent with 1958 Dobson spectrophotometer ozone measurements, inconsistent with present-day Antarctic observations, and inconsistent with meteorological and theoretical information. There is no credible evidence for an ozone hole in 1958."
