The production of an electronic edition of this translation, ten years after its printed version, puts it within reach of anyone with an internet connection. This does not totally remove all barriers to access, but we hope that this free online version will now be available to many more descendants of the people whom Parkinson described.
We thank Sydney University Press and Agata Mrva-Montoya in particular for their help in creating this new version.
