NATURAL HISTORY. 



To me be Nature s volume broad displar d ; 



And to peruse its all-instructing page, 



Or, haply catching inspiration thence, 



Some easy passage, raptur d to translate.&quot; THOXSON. 



III. AMPHIBIA (from two Greek words, meaning both and life), 

 Animals with cold red blood, breathing by lungs, capable of 

 subsisting for a time either on laud or in water. 



IV. PISCES (fishes). Animals with cold red blood, breathing by 

 gills, and not by lungs. 



V. INSECTA (insects). Animals with cold white blood, having 

 antennae (feelers) on the head, and articulated (jointed) horny 

 organs of motion. 



VI. VERMES (worms). Animals with cold white blood, without 

 antennas, for the most part with tentacula (having simple thread 

 like organs for protrusion around their mouths), and without 

 articulated organs of motion. 



165. According to the SYSTEM of CUVIER, a leading grand divi 

 sion prevails over the whole of these, viz., the vertebrated, from the 

 invertebrated (from the Latin verto, to turn) ; the first being dis 

 tinguished by having a back-bone, the latter by the absence of this 

 organ. The vertebrated animals are divided into four da&Si^ 

 thus : 



DIVISION L VERTEBRATA. 



Class L Mammalia. II. Aves. III. Eeptilia. IV. Pisces 



DIVISION II. MOLLUSCA. 



[This is the commencement of the invertebrated division, but the 

 fcerm is disused.] 



Class 1. Cephcdapoda. II. Oteropoda. III. Gasteropoda. 

 IV. Acephala. V. Bradiiopoda. VI. Cirrhopoda. 



DIVISION III. ARTICULATA. 



Class I. Annelides. II. Crustacea. III. Aradinidet. 

 IV. Insect. 



SUB-DIVISION IV. RADIATA. 



Class I. Echinodermata. II. EntozocL III. Acalepha 

 IV. Polypi. V. In/usoria.
