When we know more of the skeletons of the various species 

 of Aepyornis I believe several of those at present recognised will 

 prove to have been founded on sexual characters but at present 

 the measurements of the few parts known do not permit of this 

 being definitely settled. I personally think eventually the case 

 will prove to be as follows.
