explained.  No doubt organic beings, like all other objects, can be classed in many 
ways, either artificially by single characters or more naturally by a number of characters.  We know, for instance, that minerals and the elemental substances can be thus arranged; 
in 
this case there is of course no relation to 
genealogical succession, and no cause can at present 
be assigned for their falling into groups.  But with organic beings the case is different, and the view above given explains 
their natural arrangement in group under group; and no other explanation has ever been attempted.  |

to arrange the species, genera, and families in each class, on what is called the Natural System.  But what is meant by this system?  Some authors look at it merely as a scheme for arranging together those living objects which are most alike, and for separating those which are most unlike; or as an artificial means for 
enunciating, as briefly as possible, general propositions,— that is, by one sentence to give the characters common, for instance, to all mammals, by another those common to all carnivora, by another those common to the dog-genus, and 
 then, | then, 1866 1869 1872 |  | then 1859 1860 1861 |  
  
by adding a single sentence, a full description is given of each kind of dog.  The ingenuity and utility of this system are indisputable.  But many naturalists think that something more is meant by the Natural System; they believe that it reveals the plan of the Creator; but unless it be specified whether order in time or space, or 
 both, or what | both, or what 1861 1866 1869 1872 |  
| what 1859 1860 |

Linnæus, and 
which we often meet with in a more or less concealed form, that 
the characters do not make the genus, but that the genus gives the characters, seem to imply that something more 
is included in our 
 classification | classification 1861 1866 1869 |  | classification, 1859 1860 |  | classifications 1872 |
