Wallace Line connected islands on the west (Sumatra, Java, etc.) with the Asian continent and with similar wildlife, and islands on the east such as New Guinea were connected to Australia and were characterised by the presence of marsupials. Wallace used his extensive travel in the region to propose a line to the east of Bali since "all the islands eastward of Borneo and Java formed part of an Australian or Pacific Continent, from which they were separated." The name 'Wallace's Line' was first used by Thomas Huxley in an 1868 paper to the Zoological Society of London, but showed the line
Dwane Wallace After the war, Wallace quickly developed an all-metal replacement of the C-34—the Cessna 190 / Cessna 195, a speedy 6-seat, single-engine, executive aircraft, powered by a large, traditional radial engine. Wallace then guided Cessna away from the pioneering un-braced "cantilever"-wing design concepts of Clyde Cessna, towards more conservative-and-traditional, "strut-braced," high wings—producing the world's most successful line of single-engine light aircraft, ranging through numerous variants from the Cessna 120/Cessna 140 to the Cessna 207—despite the industry's move towards cantilever wings. The 120/140 also was the beginning of Cessna's conversion to smaller-cabin aircraft with streamlined, flat, horizontal-cylinder engines. The 120/140's distinguishing feature,
