pain. Tindale states that the Dieri 
tribe called them ooga and mura- 
mura, meaning ‘‘eyes that stared 
hard at you/’ while the Wadikali 
tribe called them rnindjimindjil- 
para , with something of the same 
meaning. 
This graph (Fig. 3) is included 
in support of the writer’s theory 
of the genesis of Australite forms. 
The group (A2h, lenses and lens 
cores) is the largest in the South 
Australian Museum collection. 
The series was firstly arranged 
according to weights, from the 8 
that averaged 39 grams, then to 
the maximum number of 613 
averaging 5.3 grams, down to the 
minimum of the 54 smallest speci- 
mens, averaging 2 grams. 
The graph of weights is a gently 
curved line. That of sizes in milli- 
metres is an almost straight line. 
The significant fact is that the line 
showing the numbers of each 
weight-size group is a normal dis- 
tribution curve, as found in the 
graphs of varying factors in most 
natural objects. The largest known 
specimen is 218 grams, and the 
smallest .15 grams. 
Assuming that they all started as 
spherical or oval forms, still hot, 
spinning as shown in Figure 2A, 
the forward part may have been 
further melted by the friction of 
the air, flowing backward to form 
a flange. All Australites show 
evidence of two distinct periods of 
melting. 
Where the flange was developed, 
it later, in most cases, melted and 
disappeared, and thus we get the 
lens, the commonest form. The
