Thing 9

Flickr was interesting - I always like looking at good photographs. I searched on "Charles Darwin" and found a few interesting things, though no previously unknown letters even after 35 pages. Still, there was a page from CD's botanical specimen book about a rust disease in wheat in South America: John Stevens Henslow had used this when he published an article in \Gardener's Chronicle\ 28 Sep. 1844 p. 659, but Duncan Porter (\Bulletin of the British Museum of Natural History (hist. ser.)\ 14(2): 145-223) described it in 1986 as missing. Apparently the photo was taken at the New York Academy of Sciences. And there's a photo of Charles Lyell's \Principles of geology\ annotated by CD that apparently was photographed here. However, I don't know what cd be done to stop people taking photographs in the building, unless people had to go through the same procedures that they use at airports.
