Their hypothesis explains so many facts.
An unproven hypothesis of the existence of things can be useful.
There is no data to accept or refute this hypothesis.
The Chemistry of the Sun (1887) is an elaborate treatise on solar spectroscopy based on the hypothesis of elemental dissociation through the intensity of solar heat.
At any rate this hypothesis suggests an explanation of many hitherto inexplicable facts.
The original hypothesis of Baeyer suggested that the course of events is the following: the carbon dioxide is decomposed into carbon monoxide and oxygen, while water is simultaneously split up into hydrogen and oxygen; the hydrogen and the carbon monoxide unite to form formaldehyde and the oxygen is exhaled.
The schedule now called for hypothesis testing.
The special Darwinian hypothesis - natural " selection " - may or may not be true; it was at least a fruitful suggestion.
Whether or not further study of the scripts of these writers confirms this hypothesis, it cannot fail to throw light on the nature of the intelligence involved.
The atomic theory has been of priceless value to chemists, but it has more than once happened in the history of science that a hypothesis, after having been useful in the discovery Present and the co-ordination of knowledge, has been aban- position doned and replaced by one more in harmony with later of the discoveries.
It may be replied that there are such facts, and though they are but few as yet, they suffice to suggest an hypothesis that may eventually prove to be a law.
One hypothesis supplants the various principles of life; the rule of absolute mechanism is as complete in the animal as in the cosmos.
Finally, there is the hypothesis that marsupials are the descendants of placentals, in which case, as was suggested by its discoverer, the placenta of the bandicoots would be a true vestigial structure.
Modern naturalists consider that many of the problems of Australia's remarkable fauna and flora can be best explained by the following hypothesis: - The region now covered by the antarctic ice-cap was in early Tertiary times favoured by a mild climate; here lay an antarctic continent or archipelago.
On the latter hypothesis it has been generally assumed that the wild camels are the descendants of droves of the domesticated breed which escaped when certain central Asian cities were overwhelmed by sand-storms. This theory, according to Professor Leche, is rendered improbable by Dr Sven Hedin's observations on the habits and mode of life of the wild camel.
For it is almost impossible to prove that any structure, however rudimentary, is useless - that is to say, that it plays no part whatever in the economy; and, if it is in the slightest degree useful, there is no reason why, on the hypothesis of direct creation, it should not have been created.
Apart from the weighty arguments which the development furnishes against the theories of Allman and Mechnikov, it may be pointed out that neither hypothesis gives a satisfactory explanation of a structure universally present in medusae of whatever class, namely the endoderm-lamella, discovered by the brothers O.
He is indeed careful to keep right with the orthodox doctrine of creation by saying that he does not believe the world actually arose in this mechanical way out of the three kinds of elements which he here supposes, but that he simply puts out his hypothesis as a mode of conceiving how it might have arisen.
In the worst case scenario of the hypothesis, the model maker is forced just to formulate hypotheses about them.
The careful and complete collection, by Franke, of the philological evidence at present available, has raised this hypothesis into a practical certainty.
