All these older methods have, however, been thrown into the background and rendered antiquated by inventions which have grown out of Hertz's scientific investigations on the production of electric waves.
Another group of investigations that seems to play an important part in the future development of the theory of evolution relates to the study of what is known as organic symmetry.
The weakness of the NeoLamarckian view lies in its interpretation of heredity; its strength lies in its zealous study of the living world and the detection therein of proximate empirical laws, a strength shared by very many bionomical investigations, the authors of which would prefer to call themselves Darwinians, or to leave themselves without sectarian designation.
The results of these investigations show that in Ceylon from the 3rd century B.C. onwards there has been a continuous succession of teachers and scholars.
His first original paper (1799) was on the compounds of arsenic and antimony with oxygen and sulphur, and of his other separate investigations one of the most important was that on the compound ethers, begun in 1807.
Investigations carried out by Blackman, and by Brown and Escombe, have shown clearly that the view put forward by Boussingault, that such absorption of gases takes place through the cuticular covering of the younger parts of the plant, is erroneous and can no longer be supported.

Investigations of every kind which have been based on original sources of knowledge may be styled "research," and it may be said that without "research" no authoritative works have been written, no scientific discoveries or inventions made, no theories of any value propounded; but the word also has a somewhat restricted meaning attached to it in current usage.
Again, the practical engineers who are building aeroplanes, and those who are making practical tests by actual flight in those machines, cannot be called "researchers"; that term should be confined to the members, for example, of the scientific committee appointed by the British Government in 1909 to make investigations regarding aerial construction and navigation.
Recent investigations have recalled attention to the work of Lowthian Green, but the question is still in the controversial stage.'
Very important are also the investigations which show how, for instance in such fundamentally different groups as petrels and gulls, similar bionomic conditions have produced step by step a marvellously close convergence, not only in general appearance, but even in many details of structure.
This interval was diligently devoted to the pursuit of classical and historical studies, to preparing himself for ordination, and to searching investigations, under the stimulus of continual discussion with a band of talented and congenial associates, of the profoundest questions in theology, ecclesiastical polity and social philosophy.
In June 1835 Airy was appointed Astronomer Royal in succession to John Pond, and thus commenced that long career of wisely directed and vigorously sustained industry at the national observatory which, even more perhaps than his investigations in abstract science or theoretical astronomy, constitutes his chief title to fame.
The chloride SC1 2 according to the investigations of 0.
Recent investigations in the government of Moscow have revealed that 40% of the peasant households possessed no horses, and similar inquiries in 41 governments elicited the fact that 28% of the peasant households were without horses, although of the total number of horses in the country 82% belong to the peasantry.

About the same time appeared his elaborate memoir, " On Faraday's Lines of Force," in which he gave the first indication of some of those extraordinary electrical investigations which culminated in the greatest work of his life.
The instruments which he devised for these investigations were simple and convenient, but could not have been thought of for the purpose except by a man whose knowledge was co-extensive with his ingenuity.

Davy, Count Rumford, all concerned themselves with thermochemical investigations of such processes.
After the investigations of Hess and Andrews, a great deal of excellent experimental work was performed by P. A.
Greatest among modern Asiatic explorers (if we except Prjevalsky) is the brave Swede, Professor Sven Hedin, whose travels through the deserts of Takla Makan and Tibet, and whose investigations in the glacial regions of the Sarikol mountains, occupied him from 1894 to 1896.
One of the results of these investigations was to extend the meaning of the word mechanism, and comprise under it all laws which obtain in the phenomenal world, not excepting the phenomena of life and mind.
