Who were "Dawson and Wilson" (mentioned as authors of an embryonic postmortem examination method)?
This article (A Note on the Staining of the Skeleton of Cleared Specimens with Alizarin Red S) looks to be the one by Dawson.

Update: I think the Wilson your text is referring to is James G. Wilson, an important researcher on terathology. I can't find any reference to a single article, though.
