This "theory of the organism," which holds so important a place in biology even at the present day, is developed by Schwann in the concluding pages of his book.
Almost his greatest service to biology was that he made biologists realise as they never did before the vast importance of environment.
It is in this return to the Cuvierian or functional attitude to the problems of form that we hold Roux's greatest service to biology to consist.
But this limitation of outlook, if carried over from morphology to general biology becomes harmful, since it wilfully ignores one whole side of life--and that the most important.
They had as good as no influence upon morphological theory, nor indeed upon biology in general.
But if any of these are destined to give the future direction to biology, they will in a measure only be bringing biology back to its pre-materialistic tradition, the tradition of Aristotle, Cuvier, von Baer and J.
He took biology into the open air, away from the museum and the dissecting-room.
Teleological explanations have long been banished from the physical sciences, and in biology they are only a last resort when physical explanations have proved incomplete (p.
But he brought to bear upon the central problems of biology an unbiassed and powerful intelligence, and his attitude to these problems, just because it is that of a cultivated layman, is singularly illuminating.

We shall treat in this place of the general biology and habits of the hominoxious forms and reserve for the systematic section the discussion of the characteristics of the different genera.
Strickland's (1914) studies on the biology of the rat flea, Ceratophyllus fasciatus, have so important a general bearing that we shall cite them in considerable detail.

Biology of Stomoxys calcitrans and other coprophagous flies.
The biology of Tabanus striatus Fabricius, the horsefly of the Philippines.
And at the same time another result may be that the science ofbiology shall come to be appraised publicly more nearly at its real value.
The ideals of biology and sociology need not coincide, often they do not, but they must not conflict.
Biology has learned much from Physics and Chemistry, but the biological applications of the laws of these sciences must be carried out with the greatest care.
The independent rediscovery of Mendel's formulas of heredity, about ten years ago, was probably the most important event in the history of biology and evolution since the publication of "The Origin of Species.
The coming together of biology and sociology, and their common search for guiding principles in their common endeavor is likely to have results of several kinds.
We might suggest here some of the topics upon which biology has information of value in this bio-social field; many of these we shall discuss later on from our present and special point of view.
And as one phase of this new partnership we have the subject of Eugenics--the science of racial integrity and progress, built upon the overlapping fields of Biology and Sociology.
For the solution of this problem biology will have to depend largely on experiments in which it is possible to influence the formation of sex characters and of the sex glands themselves.
Biology will be scientific only to the extent that it succeeds in reducing life phenomena to quantitative laws.
Some authors object to the tendency toward reducing everything in biology to mathematical laws or figures; but where would the theory of heredity be without figures?
The reader is referred to this book for the literature and main facts on the structure of the egg; it should also be stated that Conklin's book is one of the best introductions to modern biology in the English literature.
It is a summer college supported by a number of leading universities, to which graduate students come for courses in biology and marine life.
One of my instructors in biology is there," Colin said.
Alfred Fouillée says: “Since biology and sociology are so closely related, may not the laws that are common to them be expected to suggest still more universal laws of nature and thought?
Hutton, afterwards Professor of Biology and Geology at Canterbury, N.
Although social life is not so closely similar to animal life as was thought previously, the principles of biology are important to the sociologist because biology is the science of all life.
He put too much emphasis on biological resemblances in the opinion of present-day sociologists, but his emphasis on inductive study and his generalizations from biology were important contributions to the development of the new science.
Particularly did the method of evolution that had become so famous in biology appeal to students of sociology as the only satisfactory explanation of social change.
What teacher sees in biology all the grandeur of the evolution of the race, or imparts to his pupils the noble lessons of life that the study of this subject should suggest?
The study of geography in the school does not make travel particularly easier, nor does the study of biology tend to populate the earth.
In more recent years we have again seen the same method of reducing science to a variety show for the entertainment of the tired general reader applied to both biology and psychology.
Now, sir, there is in biology the thing known, as the sport.
There is a feeling abroad now, to which biology and Darwinism lend some colour, that theory is simply an instrument for practice, and intelligence merely a help toward material survival.
The point at issue between vitalism and mechanism in biology is whether the living processes in nature can be resolved into a combination of the material.
This vitalism is not a kind of biologymore prudent and literal than the mechanical kind (as a scientific vitalism would be), but far less legitimately speculative.
The writings of Bolsius on biology won for him a membership in the scientific societies of Russia, Belgium, Italy and Holland.
As already stated, page 40, the use of the method of experiment in the field of biology is, unfortunately, very limited.
The same principle applied in biology ought to establish the law of evolution, for it also explains all the facts of biology as no other law can.
I know full well that many think with Haeckel that biologywas kept back half a century by the baneful authority of Cuvier and Agassiz; but I can not think so.
Agassiz advanced biology to the formal stage; Darwin carried it forward, to some extent at least, to the physical stage.
The 'vestiges' and 'survivals' so common in Biology and Sociology are residuary phenomena.
The storage of effects is a fact of the utmost importance in all departments of nature, and is especially interesting in Biology and Sociology, where it is met with as heredity, experience, tradition.
But the hypothesis of special creation is not only a mere specious mask for our ignorance; its existence in Biology marks the youth and imperfection of the science.
Shall Biology alone remain out of harmony with her sister sciences?
And I am not aware that I spoke of biology or the cosmic urge!
But in biology and psychology quite different characteristics become essential; age and memory, heterogeneity of musical phases, irreversible rhythm "which cannot be lengthened or shortened at will.
The temptation was to make a kind of less severe and rigorous mathematics of biology itself.
The affirmative seems all the more inevitable inasmuch as the language of transformism is the only language known to the biology of today.
Biology will do the same for the world of life when biology is completed by a knowledge of the centre of all life, the brain.
II Now, Biology shows that plants and living creatures develop from a single microscopic cell, formed by the union of two half-cells, of which each half was contributed by one of the two parents.
If now, the reader has grasped these leading principles of Plant-biology, he is in a position to follow the new application of them to Human Biology which I now venture to present.
Its Biology is in the lives and loves, the hopes and fears, the throes and tears of human souls and stories.
For Biology recognises no Theology except its own--that of Evolution.
I told him I had spent some years at the Royal College of Science, and had done some researches in biology under Huxley.
I did my Biology at University College,--getting out the ovary of the earthworm and the radula of the snail, and all that.
