In the then state of knowledge, it appeared that all the species of animals and plants could be arranged in one series, in such a manner that, by insensible gradations, the mineral passed into the plant, the plant into the polype, the polype into the worm, and so, through gradually higher forms of life, to man, at the summit of the animated world.

We cannot trace the gradations of this political revolution, but we know that it met with determined opposition from the crown, which resulted in the utter destruction of the Arpads, who, while retaining to the last their splendid physical qualities, now exhibited unmistakeable signs of moral deterioration, partly due perhaps to their too frequent marriages with semi-Oriental Greeks and semi-savage Kumanians.

- It is obvious that the Linnaean binomial terminology and its subsequent trinomial refinement for species, sub-species, and varieties was adapted to express the differences between animals as they exist to-day, distributed contemporaneously over the surface of the earth, and that it is wholly inadapted to express either the minute gradations of successive generic series or the branchings of a genetically connected chain of life.
Such gradations, termed " mutations " by Waagen, are distinguished, as observed, in single characters; they are the xx.
The minute gradations observed by Hyatt, Waagen and all invertebrate palaeontologists, in the hard parts (shells) of molluscs, &c., are analogous to the equally minute gradations observed by vertebrate palaeontologists in the hard parts of reptiles and mammals.
The distinction between electi and auditores, however, does not exhaust the conception of the Manichaean Church; on the contrary, the latter possessed a hierarchy of three ranks, so that there were altogether five gradations in the community.
Similar gradations occur in the compensations paid for various injuries and insults, in fines and, among some tribes, in the value attached to a man's oath.
Between these two classes of gardens there are many gradations, but our remarks will chiefly apply to those of larger extent.
Similar gradations are observed in the direct effect of the parasite on the host, which may be local (Hemileia) when the mycelium never extends far from the point of infection, or general (Phytophthora) when it runs throughout the plant.
Buffon, in a cautious, tentative fashion, suggested rather than stated the mutability of species and the influence of the forces of nature in moulding organisms. Immanuel Kant, in his Theory of the Heavens (1755), foreshadowed a theory of the development of unformed matter into the highest types of animals and plants, and suggested that the gradations of structure revealed by comparative anatomy pointed to the existence of blood relationship of all organisms, due to derivation from a common ancestor.
It is part of Hegel's plan to remedy this one-sided character of thought, by laying bare the gradations of ideas.

If the effort varies by insensible gradations, the energy exerted is the integral or limit towards which that sum approaches continually as the divisions of the path are made smaller and more numerous, and is expressed by JPds.
It was not only by the formation of ever new endogamous castes and sub-castes that the system gained in extent and intricacy, but even more so by the constant subdivision of the castes into numerous exogamous groups or septs, themselves often involving gradations of social status important enough to seriously affect the possibility of intermarriage, already hampered by various other restrictions.
From the labours of his pupil Miotto sprang that branch of the glass trade which is concerned with the imitation of gems.

Above this tropical zone in the mountainous regions are to be found all the varying gradations of climate which we are accustomed to associate with changes in latitude.
Cases in which the variation is most extreme some botanists would prefer to consider as forming distinct species; but others, as De Vilmorin, having regard to the general facts of the case and to the numerous intermediate gradations, look upon all the forms as derivatives from one.

The fatty (fixed) oils and fats form a well-defined and homogeneous group of substances, passing through all gradations of consistency, from oils which are fluid even below the freezing-point of water, up to the hardest fats which melt at about 50° C. Therefore, no sharp distinction can be made between fatty oils and fats.

The picture thus presented by Hindu society - as made up of a confused congeries of social groups of the most varied standing, each held together and kept separate from others by a traditional body of ceremonial rules and by the notion of social gradations being due to a divinely instituted order of things - finds something like a counterpart in the religious life of the people.
A series of the apes, arranged from lower to higher orders, shows gradations from a brain little higher that that of a rat, to a brain like a small and imperfect imitation of a man's; and the greatest structural break in the series lies not between man and the manlike apes, but between the apes and monkeys on one side, and the lemurs on the other.
