CHECAGP ay LV): 
EXTRA-LIMITAL PETROGLYPHS. 
Phe term ‘‘extra-limital,” familiar to naturalists, refers in its present 
connection to the sculptures, paintings, and drawings on rocks beyond 
the continents of North and South America, which are now introduced 
for comparison and as evidence of the occurrence throughout the world 
of similar forms in the department of work now under examination. 
SECTION 1. 
AUSTRALIA. 
Mr. Edward G. Porter (a), in “The Aborigines of Australia,” says: 
“Their rock carvings are only outline sketches of men, fish, animals, 
etc., sometimes seen on the top of large flat rocks. Two localities are 
mentioned, one on Sydney common ou EUROS on a rock between 
Brisbane water and Hawkesbury river.’ 
Much more detailed information is given by Thomas Worsnop, viz: 
At Chasm island, which lies 1} miles from ‘‘Groote Eylandt,” in the steep sides of 
the chasms, were deep holes or caverns undermining the cliffs, upon the walls of 
which are found rude drawings, made with charcoal and something like red paint, 
upon the white ground of the rock. These drawings represented porpoises, trrtle, 
kangaroos, and a human hand, and Mr. Westall found the representations of a kan- 
garoo with a file of thirty-two persons following after it. 
In the MacDonnell ranges, 6 miles from Alice springs, in a large cave, there were 
paintings made by the aborigines, well defined parallel lines, intersected with foot- 
prints of the emu, kangaroo rat, and birds, with the outlines of iguana, hands of 
men, well sketched and almost perfect. 
The parallel lines were of deep red and yellow colors, with brown and white bor- 
ders; the footprints of light red, light yellow, and black; the outlines of the ani- 
mals and hands were of red, yellow, white, black, wonderfully (considering it was 
done by savages) displayed and blended. All] the paintings were in good preserva- 
tion and evidently touched up occasionally, as they looked quite fresh. 
I can only conjecture that these paintings were left as a record, a life-long charm, 
against the total destruction of the above animals. The paintings were seen by Mr. 
S. Gason, of Beltana, in the year 1873. 
Very interesting groups of native drawings are to be seen in the caves of the 
Emily gorge in the MacDonnell ranges. Many of these drawings represent life-size 
objects.
