There are no sudden transformations; all the operations of nature are on a gigantic and grand scale, invariably commencing from the most simple forms, which are aggregated into the most complicated. Even in the highest organic structure represented by man, we discover in the virile fluid an essential element of future life, represented by a microscopic monad or vital molecule, with a caudal appendage, having distinct independent existence; in fine, the lowest form of organic vitality being an essential element to propagate the highest; that too resembling a tadpole, only not being one thousandth, the size. This sperm monad varies in different classes of animals, and unquestionably is a necessary existence in order to insure the propagation of the species. When the female frog has spawned, this seed would not bring forth if the male did not impregnate it. The same process with plants; it is necessary that the pollen of the male should impregnate the female, otherwise there is no fruit. Here we have the universal law exemplified in the necessary presence of the two forces, negative and positive, or the attractive and repulsive. No operation in the whole arcana of nature, from the most simple to the most comprehensive, but demands the active presence of these forces.

Sterility, extinction, death, are the inevitable consequences when the forces cannot operate in unison; there are no products, no propagation of the species, and the race runs out.

Do not the seasons, on a large scale, represent this negative and positive principle, in the relative action of the solar influence on the earth, in accordance with its position?

In the spring of the year does not the positive state cause the sap to rise, the buds to come forth, the trees to be covered with leaves and flowers? The whole face of the vernal portion of the earth is decked in beauty and youthful vigour; at the same time the antipodean region is suffering the effect of a negative state.

The earth's magnetic state produces a direct effect on all the forms of creation, and materially modifies the powers or functions of reproduction. All bodies possess organized magnetism, and the phenomenon presented is in accordance with the special organization with which it is associated.

All forms of motion emanate from the operation of the two forces. It must be backward or forward, upwards or downwards, expansive or contracting; if there is a force to repel there must be one to attract.

All the forms and modifications that exist in the universe are the result of matter, force, and motion. The very component parts of the earth are a mixture of acids and alkalies. This condition enters largely into the composition of the vegetable and animal forms of matter, producing their alternate expansions and contractions. These mark the growth and decay of life; at the point where the attractive and contracting forces cease, the repelling and expansive forces commence. It is thus that the course of constant alternate destruction and reproduction is continued.

In conclusion, no one who attempts theorizing as to the origin of man or any other animal, must omit the fundamental principle, that the earth's telluric or electro-chemical state at special periods must have played a most important part in the special creation.

There is a constant correlation or harmony of the laws which have been directly instrumental in bringing into existence these special organizations. They are repeated in the embryological development, in the metamorphosis of ovum into the larva, and thence into the pupa and butterfly.

It is, however, no more difficult to conceive a special creation than that a state should exist which would cause one species to evolve another higher than itself; still, that the condition which produced this evolution should not have supplanted or rendered extinct the original source or progenitors from which the evolution took place. This difficulty at first appears to be an insuperable argument in favour or the theory that the various developments were distinct and special creations, in accordance with the earth's generative state.

Even supposing this to have been the case, we do not overcome the absolute necessity that the germ or ovum of the superior organization demanded a mother or receptacle, wherein gestation should be gradually accomplished, and even after birth that the future being should be nurtured and protected during its early period of helplessness.

We are not driven from this fact to adopt the hypothesis, that our immediate progenitors belonged to the quadrumana or superior Simiadae, which are now found on particular zones of the earth. It is more than probable that many important links in the zoological chain have been destroyed or become extinct. We have as many grades of the monkey as there are types of man, each possessing a particular geographical characteristic. Many lower types of man have disappeared, as also the animals which immediately preceded him.

In any case, we are forced to follow the natural law of production.

To imagine a perfectly matured being, created without having to pass through the various stages of embryonal development, infancy manhood, is to deny the evidence of our experience, and to make the creation of man an exception to the rest of the natural laws which surround us. If man did exist exceptionally as regards the laws which are essential to the rest of the animal world, then he might have had an exceptional creation; but we find him subject to all the contingencies and vicissitudes of the elements, like the lowest organizations. He only exists so long as he obeys the laws common to all created things.

The struggle of life over untold ages has been the lot of man. He has had to battle continually in his primate condition, not only with the elements; he had to seek refuge in caves and places inaccessible to the numerous powerful carnivora. Savage in his nature, he destroyed his own kind, or those closely resembling himself. At this period he did not possess the faculty of speech, except to the most limited extent.

It can be conceived how man, in this early period, should have occupied his whole thought with the preservation of his existence. His natural inherent faculties were brought into functional exercise by the imperative necessities with which he was surrounded. In this state he would have remained to the present hour, had not the physical condition of the earth itself become more favourable for his advance and development.

It is a notorious fact, that certain zones of the earth are at this day favourable for the healthy condition of specific races, who if they change locality become the victims of disease and early death. If this is the case at this period of the earth's existence, it is not difficult to imagine a state when even greater chemico-electrical changes were taking place, not suddenly, in a few centuries, but covering millions of* years; that man in certain zones was advanced in development, whilst others remained in the original state, whose zone of habitation was not similarly influenced. It is thus that we may account for the different races of man on the earth, whose physical characteristics are so pronounced that it is impossible to imagine that they ever originated from a single germ.

If we, however, admit the potent influence of the telluric or chemico-electric vibrations of the earth's "vital element" at particular zones, in combination with solar influence, and that man as a creature of the earth has been no exception to the rest of the universe, but brought into existence and developed in accordance with the creative function of the earth itself in special zones, we may reconcile and be enabled to account for apparent discrepancies and contradictions.

Whatever hypothesis is resorted to in the attempt to explain the original of man, it must essentially be surrounded with difficulties of such magnitude as to render the investigation one which will call forth all grades of criticism - from the pigmy critic, who indulges in invectives; the sectarian critic, who enlarges in a vainglorious style on "The ruler of the universe;" the pompous critic, who fancies himself a representative of man - "the wonder and glory of the universe;" the sarcastic critic, whose funny brain cannot get beyond the jellyfish; lastly, the gigantic critic, who mixes adroitly philosophy, science,, and nonsense: this is powerful, as it carries the public mind.
