He worked hard at his book on refraction, and dissected the heads of animals in order to explain imagination and memory, which he considered physical processes.'
6), from the bases of which arise contractile muscular processes lying in the plane of the transverse section of the body.
One result of this is that mobilization and concentration are much slower processes than they are in Germany.
But whilst all the organic processes in man go on mechanically, and though by reflex action he may repel attack unconsciously, still the first affirmation of the system was that man was essentially a thinking being; and, while we retain this original dictum, it must not be supposed that the mind is a mere spectator, or like the boatman in the boat.
Past events, " happening " to be what they were, have fixed subsequent processes to their channels.
The difficulty is in accounting for the continuance in extensive fine weather districts of large positive charges in the atmosphere in face of the processes of recombination always in progress.
WoolIn 1901, 161,000 persons were engaged in the spinning and other preparatory processes and in the weaving of wool.
The three subjects to which Smith's writings relate are theory of numbers, elliptic functions and modern geometry; but in all that he wrote an "arithmetical" made of thought is apparent, his methods and processes being arithmetical as distinguished from algebraic. He had the most intense admiration of Gauss.
Materia, matter), in philosophy, the theory which regards all the facts of the universe as explainable in terms of matter and motion, and in particular explains all psychical processes by physical and chemical changes in the nervous system.
Von Liebig (1823), who heated a mixture of alcohol, nitric acid and mercuric nitrate; the salt is largely manufactured by processes closely resembling the last.
It makes excellent charcoal, especially for metallurgic processes; the Sussex iron, formerly regarded as the best produced in Britain, was smelted with oak charcoal from the great woods of the adjacent Weald, until they became so thinned that the precious fuel was no longer obtainable.
The body-cavity is largely occupied by processes from the large muscle cells of the skin.
These processes stretch across the body cavity to be inserted in the dorsal and ventral middle lines.
Similarly the giant cells are produced at their periphery into a number of branching processes which bear similar end-organs on their surface and in some cases terminate in them.
The scientific study of electric wave telegraphy has necessitated the introduction of many new processes and methods of electrical measurement.
An immense mass of information has been gathered on the scientific processes which are involved in electric wave telegraphy.
But there are gaps in Kant's system - a imperfect gap between sensation and the sense-forms of time and space; a gap between sense-forms and thought; a gap between the lower but practicable processes of the Understanding and the higher but unrealizable ideas of Reason.
On one side, the world we know by valid processes of thinking cannot, we are told, be the real world.
Atoms swerved as they fell endlessly downwards, and thus introduced an indeterminate or irrational element into the processes of the world.
Nature exists over against Him; but its forces or processes are His own power in immediate exercise, except in so far as God has.
The muscular tissue consists primarily of processes from the bases of the epithelial cells, processes which are contractile in nature and may be distinctly striated.
The muscle-fibres arise as processes from the bases of the epithelial cells; such cells may individually become sub-epithelial in position, as in the polyp; or, in places where muscular tissue is greatly developed, as in the velum or sub-umbrella, the entire muscular epithelium may be thrown into folds in order to increase its surface, so that a deeper sub-epithelial muscular layer becomes separated completely from a more superficial bodyepithelium.
M, Muscular processes of the ectoderm-cells in cross section.
Each such sporosac has two long tentacle-like processes thickly ciliated.
These processes have been studied in detail by A.
The various grades of life on our planet are the natural consequences of certain physical processes involved in the gradual transformations of the earth.
From this point of view the processes of nature from the inorganic up to the most complex of the organic become stages in the self-realization of nature.
The detailed exhibition of the organizing activity of nature in the several processes of the organic and inorganic world rests on a number of fanciful and unscientific ideas.
All these processes are regarded as a series of manifestations of a vital principle in higher and higher forms. Oken, again, who carries Schelling's ideas into the region of biological science, seeks to reconstruct the gradual evolution of the material world out of original matter, which is the first immediate appearance of God, or the absolute.
BM- Within quite recent years, however, a special school q Y P has arisen with the main object of treating the processes of evolution quantitatively.
An exact and conscientious worker, he did much to improve and systematize the processes of analytical chemistry and mineralogy, and his appreciation of the value of quantitative methods led him to become one of the earliest adherents of the Lavoisierian doctrines outside France.
The organism is largely dependent for its vital processes upon gaseous interchanges.
There is no need for cuticularization here, as the external dangerous influences do not reach the interior, and the processes of absorption which Boussingault attributed to the external cuticularized cells can take place freely through the, delicate cell-walls of the interior, saturated as these are with water.
This serves a double purpose, bringing up from the soil continually a supply of the soluble mineral matters necessary for their metabolic processes, \vhich only enter the plant in solutions of extreme dilution, and at the same time keeping the plant cool by the process of evaporation.
Brown and Escombe have shown that the amount of solar energy taken up by a green leaf may often be fifty times as much as it can utilize in the constructive processes of which it is the seat.
What is not used in the constructive processes is employed in the evaporation of the water, the leaf being thus kept cool.
Even in the higher flowering plants, in which the processes of the absorption of substances from the environment has been most fully studied, there is a stage in their life in which the nutritive processes approximate very closely to those of the group last mentioned.
The differences between the nutritive processes of the animal and the plant are not therefore fundamental, as they were formerly held to be.
While we know little of the processes of proteid-construction, we are almost completely in the dark also as to what are the particular proteids which are first constructed.
As this is not the incorporation of either into the living sobstance, but is only its manufacture into the complex substances which we find in the plant, it seems preferable to limit the term assimilation to the processes by which foods are actually taken into the protoplasm.
The discovery of the widespread occurrence of this mycorhizal symbiosis must be neld to be one of the most important results of research upon the nutritive processes of plants during the closing decade of the 19th century.
The processes of putrefaction may be alluded to as affording an instance of such a power in the vegetable organisms. At the same time it must be remembered that the secretion of enzymes by Bacteria is of widespread occurrence.
