shearing teeth cuts bearing a striking resembhince to the 

 notches made by civilised man in severing certain materials 

 with the aid of a knife or axe. There is admittedly, as regards 

 size, a srreat difference between the Myall bone and the Colon- 

 o^ulac bone, and moreover, in the latter instance we have no 

 corroborative evidence of the work of Thylacoleo in the pre- 

 sence of markings or cuts of any kind which might safely be 

 attributed to him. At the same time it throws much doubt 

 upon Avhat might otherwise unhesitatingly be accepted as the 

 handiwork of man, more especially when we know that that 

 work is not of a nature practised by the natives of Australia in 

 historical tim'es.
