Description | Rix clarifies a small mistake, stating that he had written to Dr Waller to pass on Michael Foster's doubts about the suitability of the meisenbach process for this subject, and asking him to try one sample before proceeding with the rest. The fact of their having received only one negative shows that Waller received Rix's note. He therefore asks that they proceed with the one they have, and wait for approval before proceeding any further. |
