Several examples are given, including an example of a woman whose skin turned black after she experienced grief and a hen that laid a black egg. Notes are taken from journals including the Edinburgh Medical Journal, the Lancet and Archives de Physiologie Normale et Pathologique. One note was written on the back of a printed letter from John Hutton Balfour written on 29 October 1860.

Another sheet of paper has been stamped with the seal of the Royal College of Physicians of Edinburgh. |
