good reason for believing: for Captain Short, in the 
account of his recent expedition into the interior of 
Australia, mentions the fact of two Emus swimming 
across the Morumbidgee, in a part of considerable 
width and rapidity, w T hich they would never have 
ventured to attempt, so peculiarly are they in body 
and limb unfitted for swimming, without some inter- 
nal capacity, similar to the above*. 
Of the last bird in this list, the Dodo, no particulars 
are known; for although there is no doubt of its 
having been in former times abundant in some of the 
islands of the Indian Ocean,, it has long ceased to 
exist, and must now be considered as extinct a species 
as those extraordinary animals whose bones are oc- 
casionally found in a fossil state in rocks and caves.
