82 Mr. Moncax's Description 
upon the living marsupial animal will be found sufficiently 
ample, and our opportunities for making anatomical examina- 
tions upon the dead subject are by no means rare. With such 
advantages therefore, I trust that the time is not far distant 
when we shall be furnished with a full and distinct account of 
the object of. our researches ; and that by a detail of connected 
facts, the pheenomena attending the changes which occur during 
the foetal life of marsupial animals will be as clearly under- 
stood as those which take place during the progress of genera- 
tion in other mammiferous quadrupeds.
