ADDENDUM 
After the above notes were in print, Mr. K. P. Rose of the 
Meteorological Bureau presented to the Museum a stone artefact 
with a cutting edge which he had found in Hughes’s sandpit, 
Keilor, where the fossil human skull was discovered. The imple- 
ment when found was lying on the floor of the pit, evidently not 
in situ, but it may have been discarded during excavation of the 
Pleistocene terrace deposit. It is approximately three and a 
quarter inches long, two and a half inches at its widest end, and 
an inch thick. Like the implement described above, it is a hornfels 
pebble flaked only on one side, the other side being the natural 
surface of the pebble ; and in technique, material and weathering 
the implements are similar.
