Science historian Dr John van Wyhe and his fellow researchers at the National University of Singapore have compiled the entire collection of Alfred Russel Wallace’s documented life and discoveries from his scientific travels. The memoir includes 28,000 pages of historical manuscripts and 22,000 magnificent illustrations. All these documents, published and unpublished, are now freely available on their website Wallace Online.
Flying frog
During his visit to Borneo, Wallace observed what he described in his letters as "one of the most curious and interesting reptiles [sic]". Flying frogs (Rhacophorus nigropalmatus) live in the trees of the dense tropical jungles of Malaysia and Borneo. Using their large webbed feet, the amphibians are able to leap from tree to tree, creating the illusion of flying. Image: Wallace Online
