Almost by accident, I just came across this photograph on Flickr of the figurehead of HMS Rattlesnake, the ship on which Darwin's Bulldog, Thomas Henry Huxley, voyaged as assistant surgeon from 1846–50.
Rattlesnake was to Huxley what HMS Beagle was to Darwin. It's fantastic that her figurehead still exists.
Finally I have a reason to visit Farnborough!
