NOTE. 



An interesting and instructive use of the " Chart of the Animal King' 

 dom " will be to employ the method of CLASSIFICATION, which it embodies, 

 in tracing an individual of any species, through the successive gradations, 

 to the Sub-Kingdom to which it belongs. 



1. In the VERTEBRATES, take, for example, the Common Dog, Canisfamil- 



iaris; and it may be traced as follows: The generic term (which is 

 always placed before the specific, or stands alone when the specific 

 term is omitted) is Canis; familiaris is the specific term. ."Genera 

 are formed into families ; the family name is Canidce ; families are 

 formed into sub-orders or orders (the orders are in larger or capital 

 letters) ; Canidce belongs to the sub-order DIGITIGRADA ; to the order 

 Carnivora. Orders are formed into classes. CARNIVORA belongs to 

 the sub-class UNGUICULATA ; to the class MAMMALS. Classes (denoted 

 by larger letters) are formed into SUB-KINGDOMS. The MAMMALS 

 belong to the Sub-Kingdom VERTEBRATES, denoted by letters next in 

 size to those of the "ANIMAL KINGDOM." 



2. In the ARTICULATES, take the Lobster, Astacus marinus. Marinus de- 



notes the species; Astacus, the genus of the order (or sub-class) 

 MALACOSTRACA, of the class CRUSTACEA, of the Sub-Kingdom ARTICU- 

 LATES. 



3. In the MOLLUSKS, take the Shell, Mitra episcopates. Episcopalis is the 



name of the species : Mitra, of the genus. This genus belongs to the fam- 

 ily Volutidce. The family Volutidae belongs to the order PECTINIBRAN- 

 CHIA ; this order to the class GASTEROPODS ; this class to the UNI- 

 VALVES, the first grand division of the Sub-Kingdom MOLLUSKS. 



4. In the RADIATES, take the Portugese Man of War, Physalis pelagica. 



The generic term is Physalis ; the specific term, pelagica; Physalis 

 belongs to the order SIPHONOPHORI, to the class ACALEPHS, to the Sub- 

 Kingdom RADIATES. 



The above are given as specimens in the several sub-kingdoms, showing 

 the manner in which the species named in the Chart, may in conformity 

 with the system of Classification, be followed up to their respective places.
