MONOGRAPH OP THE FALCONILLE 
The first subkingdom consists of the classes — 
I. Mammalia. II. Ayes. III. Reptiles. IV. Pisces. 
Y. Mollusc a.* 
I. Class Mammalia. — I call them, with good reason, nerve-ani- 
mals ; because in man, being the only ideal of a nerve-animal, we 
observe the most perfect and largest brain, and the most complete 
eye. Man, in whom reason has arrived at its highest possible per- 
fection, and who in his highest race, the Caucasian, has attained 
to self-consciousness, which reflects the universe, claims to himself 
the first rank as family to the primates as order, and to all ma- 
malia as Class. 
Ghent calls the mammalia, eye-head, or by my researches, nerve- 
animals. 
If we look in the class of birds for an order in which the largest 
brain, the most perfect eye, and the greatest sagacity of bird is 
to be found, and which have most analogies to man and to the 
primates, we shall find no other family than that of the Psitta- 
cidee. As man gives to all primates the first rank as an order, so 
the Psittacidce give to the Zygodactylce ( Scansores ) the first 
rank as an order. J It is not in the root or stem, but in the flower 
and fruit that we best recognise a plant. 
The family of Psittacidce , which give to the Zygodactylce the 
first rank as an order, represent the type of mammalia or nerve- 
animals in the clearest way ; they therefore represent one of the 
five types of the class of birds. Hence, if only speaking of birds, 
we may translate the denomination of nerve-head or eye-bird into 
that of parrot- type, which implies the same. 
Let us now resume the characteristics, which, with respect to 
body and intelligence, are inherent in this type, and let us inquire 
whether in other orders we find forms of which we may say, that 
Tlie reader will not be startled at my having comprehended the Mollusca 
among the higher animals ; it is not for the sake of the quinary system, but from 
reasons which will clearly appear to the reader from the further perusal of my 
researches. 
t Oken called the mammalia, sense ; the birds, nerve ; the reptiles, muscle ; and 
the fish, bone — animals. 
+ That Vigors and others classify a part of the Zygodactylce with the Passeres, 
anses from an erroneous application of analogies.
