He travelled and wrote a lot with Walter Rothschild. Some of their writing included "New mammals from Dutch New Guinea" (which was published in 1932) and a book about tree kangaroos which was called "The Genus Dendrolagus" (which was published in 1936). He was also a very good artist, showing pictures at the Royal Academy. He also drew pictures for his own scientific writings.
