Nägeli does not produce such reasons, but considers the metamorphosis of the idioplasm in ontogeny as mere differences in the ‘conditions of tension and movement.
Nägeli further assumes that organisms contain forces which cause periodical transformation of the species, and he imagines that the organic world, as a whole, has arisen in a manner similar to that in which a single individual arises.
But it is obvious that Nägeli goes too far in this respect, although it may be conceded that innate individual differences in plants are much more difficult to distinguish from those which are acquired, than in animals.
Footnote 292: Compare on this point Nägeli in his ‘Theorie der Abstammungslehre.
Could not idioplasm be built up in a manner entirely different from that which Nägeli supposes?
Curiously enough, Nägeli mentions the formation of galls in plants among his instances of purposeful reactions under external stimuli.
Nägeli attempts to explain certain selected cases of adaptation as the direct results of external stimuli.
In order to explain adaptation Nägeli assumes that, under certain circumstances, external influences may cause slight permanent changes in the idioplasm.
It is with sincere admiration and real pleasure that we read the exposition in which Nägeli gives, as it were, the result of all his researches which bear upon the great question of the development of the organic world.
Nägeli has very ingeniously worked out his conception of idioplasm, and this conception is certainly an important acquisition and one that will last, although without the special meaning given to it by its author.
Having convinced himself of this, Nägeli [1879] suggested a new explanation of the facts based on molecular-physical grounds.
In my last letter I referred to the works of Jordan and Nägeli for any number of 'facts in Nature of varieties arising among the type forms.
Passing now to singing and music, it happened very luckily for me that just at this time Nägeli and Pfeifer brought out their "Treatise on the Construction of a Musical Course according to the Principles of Pestalozzi.
Nägeli thought that there exists in living material an innate power to grow and expand.
Nägeli compared the process of evolution to the growth of a tree, whose ultimate twigs represent the living world of species.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "geli" in a variety of sentences. We hope that you will now be able to make sentences using this word.
