sheep and tigers. Commencing, then, with the creatures most like man, 

 we arrange our orders in a descending scale. The technical Latin 

 names will be explained at the beginning of our account of each order.

The above arrangement is in accordance with the conclusions of the 

 most eminent naturalists of the present da}', and is undoubtedly the most 

 convenient for a popular exposition of the Natural History of the Mam- 

 malia. We may mention, however, that many scientific writers separate 

 the Rtiviinantia from the Ungjilata, that some form Ruminantia, Ungiilaia 

 and Probosddca, and some only the two latter, into an order called 

 Pachydekmata.
