595. The author pronounces ex cathedra for the spontaneous generation of the 
lower forms of animal life, with a tone of condescending wonder at the prejudices 
opposed to the universal admission of the principle, which may provoke a smile, 
when we remember the inherent difficulties of the investigation, whether of the or¬ 
ganization or the functions in the more minute and obscure tribes, but he has 
brought neither argument nor evidence to bear upon that question. The Doctor 
Guitton seems more at home when the Yertebrata come under consideration. Here 
the physiological grounds of his classification realise a possibility already remotely 
suggested by comparative anatomy. Thus, the class resolves itself into three sub¬ 
classes, the Amphibia receding one way to join the fishes, while the Reptiles pass 
over on the other side to the birds. The Mammalia alone are treated in some de¬ 
tail, and the families sketched in a rapid review, striking and comprehensive, if 
somewhat superficial in its generality. While the higher tribes, which most ap¬ 
proach the human structure, are handled with peculiar predilection, that highest 
type is reserved; only a chapter on the structure of the arm, and the relation of this 
to the degree of intelligence, replacing the more usual topics of brain and scull in 
the materialistic view. The system is exhibited in dichotomous analysis, not as a 
convenient artifice, but as most conformable to nature ; and a scheme of u inoscu¬ 
lations ” serves to account for the seeming anomaly of retrogressive transitions in a 
constantly ascending scale. We have given, on the opposite page, a specimen table 
exhibiting the grand sub-divisions of the animal kingdom according to Guitton’s 
views. For some of the technical terms, see Burdach’s Physiology.
