506 RETROSPECTIVE VIEW OF THE RODENT ANIMALS. 
is short and marked, and the claws are rather small. The peculiar head is of an egg-like 
form. 
THERE are several other genera belonging to this curious family, among which may be 
noticed the genus Ctenomys, containing the TucuTuco, a native of Magellan Straits. This is 
also a burrowing animal, and the peculiar name by which it is known has been given to it on 
account of the curious cry which it utters as it is engaged in its subterranean labors, and which 
is said to resemble the word ‘‘'Tucutuco.” 
On taking a retrospective view of the rodent animals, the reader will not fail to observe 
the frequency with which they reproduce some idea which is more fully manifested in other 
orders of the animal kingdom. The destructive idea is not more strongly developed in the 
lion than in the rat, which will attack and kill animals of much greater strength and bulk 
than itself. It is a truly bloodthirsty being, and will kill many a rabbit or fowl for the mere 
sake of sucking the hot blood as it pours from the fatal wound. . 
The tree-loving and agile squirrel plays the same part among the rodents as the monkey 
among the quadrumana ; the flying squirrels have a close analogy to the colugo and the petau- 
rists, and they again to the bats, which in their turn partake Jargely of the bird character and 
formation. The beaver and ondatra are evident reproductions of the aquatic idea, which is 
more thoroughly developed in the seals and whales, and is carried out to its greatest perfection 
in the fishes. The rodent capybara again, with its thick, coarse, bristly hair, heavy form, 
hoof-like claws, and water-loving propensities, is no indifferent representation of the pachy- 
dermatous water hog, which also may be looked upon as corresponding to the dugong and 
manatee. Lastly, the aspalacide, or rodent mole rats, are wonderfully similar to the true 
insectivorous moles, both in habit and formation of body. 
In many instances this phenomenon is exhibited in the reverse order, the members of other 
groups exhibiting a tendency towards the rodent type. The aye-aye, for example, a quadru- 
manous animal, displays so strong a resemblance to the squirreis, that it was long ranked 
together with those animals by systematic naturalists. The hyrax again, or klip-daas, a 
pachydermatous animal, and allied closely to the hippopotamus, is externally, and even in the 
arrangement of its teeth, so rabbit-like in form, that it was as a matter of course placed among 
the rodents, until Cuvier’s accurate eye discovered its true character. The insect-eating 
tupaias of Java, with their arboreal habits and long bushy tails, are so like the squirrels that 
the popular name of a squirrel and a tupaia is identical in the countries where they reside. 
All external objects are, in their truest sense, visible embodiments or incarnations of 
Divine ideas which are roughly sculptured in the hard granite that underlies the living and 
breathing surface of the world above ; pencilled in delicate tracery upon each bark flake that 
encompasses the tree-trunk, each leaf that trembles in the breeze, each petal that fills the air 
with fragrant effluence ; assuming a living and breathing existence in the rhythmic throbbings 
of the heart-pulse that urges the life-stream through the body of every animated being; and 
attaining their greatest perfection in Man, who is thereby bound, by the very fact of his exist- 
ence, to outspeak and outact the Divine ideas, which are the true instincts of humanity, before 
they are crushed or paralyzed by outward circumstances. Only thus can man be truly the 
image and likeness of God, only thus can the Divine ideas be truly manifested in him to the 
world. For just in proportion as he shrinks from speaking the truth that is in him, or from 
acting the good that is in him, so far he stifles the commencing outbirth of Divine power, and 
becomes less and less godlike. 
Hence the necessity for the infinitely varied forms of animal life. Until man has learned 
to realize his own microcosmal being, and will himself develop and manifest the god-thoughts 
that are continually inbreathed into his very essential nature, it needs that the creative ideas 
should be incarnated and embodied in every possible form, so that they may retain a living 
existence upon earth,
