The Island of the Colour-Blind
1996, Pan Macmillan, Sydney
This is two books in one - the first is about Sacks' journey to a small Pacific island where a high percentage of the population is totally colour blind; the second is about Guam where a neurological disease causes muscular weakness.
I expected this to be more about the neurology and science of the diseases, but it read more like a travel diary which just happened to centre around a neurologist's study travels. It was interesting to read about these places and conditions which I'd never heard about before but I would have liked a little bit more in-depth.
