That caught my eye as well! No mention in the article, but on the scribbled out page of Emma Darwin's diary, she's describing how she's been ill, and what she's been eating (interestingly, I suspect she was trying to see if what she ate helped/harmed how she felt).

Starting on Sunday, it says:

Sick from half-past 12 to 5. 9 or 10 __ ___ copiously ___ ...

Took only ____ 2 raw eggs ...

Eliza __.. afternoon

slept tolerably but much flatulence.

had an egg + toast this morning.

feels [sic?] pretty well.

I saw that too, and LOL'd.
