to the circumference.* The circular incised sculpture is very 
common on many petroglyphs, particularly in America, such as 
Bald Friar Bock, in Maryland ; Girao, in Brazil; Cipreses, in 
Chili, and on the Colorado River, Utah,! and it is certainly 
curious to find this form of ornamentation whether on implements, 
as pictographs on the walls of Cave-shelters, or as petroglyphs, 
so widely distributed. It is curious and even startling to find 
the close general resemblance there is between this circular and 
spiral incised ornament on our Black’s weapons, and in their 
Cave-shelters, and those curious petroglyphs found in odd quarters 
of the globe, and known as “cup-sculptures,” both with and 
without a radial groove. Many of these were described by the 
late Mr. George Tate, occurring on Northumbrian (England) 
rocks, both circles and ovals, mostly with a radial groove.} Mr. 
Tate regarded them as the work of a Celtic race, and “symbolical 
most probably of a religious nature.” Dr, B. Seemann has 
figured precisely similar closed concentric circles from the rock 
surfaces in Yeraguas, New Granada, and believes them to have 
been produced by a very ancient people of that country, and to 
be “symbols full of meaning” to those who executed them. 
I have lately seen a number of single circles on the petroglyphs 
of the Hawkesbury country around Narabine Lagoon, between 
Manly and Pittwater, both separately incised and forming portions 
of compound figures. 
A SPEAR with INCISED ORNAMENT from ANGELDOOL, 
NEW SOUTH WALES. 
By R. Etheridge, June., Curator. 
A remarkably ornamented spear has been received from 
Angeldool, on the Narran River, by Dr. James C. Cox, who has 
been kind enough to present it to the collection. It is made 
from a sapling of light coloured hardwood, eleven feet nine inches 
long and two and a-half inches in its greatest circumference, 
tapering at both ends to a point. Unlike a very large number
