It also inhibits investigations and makes for an early Christmas present for defense attorneys.
His investigations on vinegar-making revolutionized that industry, and he showed how, instead of waiting two or three months for the elaboration of the process, the vinegar could be made in eight or ten days by exposing the vats containing the mixture of wine and vinegar to a temperature of 20 to 25° C., and sowing with a small quantity of the acetic organism.
His investigations on the synthesis of organic compounds were published in numerous papers and books, including Chimie organique fondee sur la synthese (1860) and Les Carbures d'hydrogene (1901).
Of lost works by Archimedes we can identify the following: (I) investigations on polyhedra mentioned by Pappus; (2) Archai, Principles, a book addressed to Zeuxippus and dealing with the naming of numbers on the system explained in the Sand Reckoner; (3) Peri zygon, On balances or levers; (4) Kentrobarika, On centres of gravity; (5) Katoptrika, an optical work from which Theon of Alexandria quotes a remark about refraction; (6) Ephodion, a Method, mentioned by Suidas; (7) Peri sphairopeoia, On Sphere-making, in which Archimedes explained the construction of the sphere which he made to imitate the motions of the sun, the moon and the five planets in the heavens.
Bent's account of the Ruined Cities of Mashonaland, but the popularity of that work disseminated a romance concerning their age and origin which was only dispelled when scientific investigations undertaken in 1905 showed it to be wholly without historical warrant.
Medical science further owes to him the classification of new growths on a natural histological basis, the elucidation of leucaemia, glioma and lardaceous tumours, and detailed investigations into many diseases - tuberculosis, pyaemia, diphtheria, leprosy, typhus, &c. Among the books he published on pathological and medical subjects may be mentioned Vorlesungen fiber Pathologic, the first volume of which was the Cellular-pathologic (1858), and the remaining three Die Krankhaften Geschwiilste (1863-67); Handbuch der speziellen Pathologic and Therapie (3 vols., 1854-62), in collaboration with other German surgeons; Gesammelte Abhandlungen zur wissenschaftlichen Medizin (1856); Vier Reden fiber Leben and Kranksein (1862); Untersuchungen fiber die Entwicklung des Schlidelgrundes (1857); Lehre von den Trichinen (1865); Ueber den Hunger-typhus (1868); and Gesammelte Abhandlungen aus dem Gebiete der afentlichen Medizin and der Seuchenlehre (1879).
His optical investigations are perhaps the subject in which he most contributed to the progress of science; and the lucidity of exposition which marks his Dioptrics stands conspicuous even amid the generally luminous style of his works.
The investigations of Lord Rayleigh and Sir William Ramsay had shown that indifference to chemical reagents did not sufficiently characterize an unknown gas as nitrogen, and it became necessary to reinvestigate other cases of the occurrence of "nitrogen" in nature.
Lucian's own close investigations into Alexander's methods of fraud led to a serious attempt on his life.
4, containing a history and bibliography of Black Hills investigations); also R.
He carried out a number of magnetic investigations which resulted in the discovery of many interesting phenomena, some of which have been rediscovered by others; they related among other things to the effect of mechanical strain on the magnetic properties of the magnetic metals, to the relation between the chemical composition of compound bodies and their magnetic properties, and to a curious parallelism between the laws of torsion and of magnetism.
From Stolze's investigations it appears that at least one of these, the castle built by Xerxes, bears evident traces of having been destroyed by fire.
His experimental investigations are carried out with plain and usually home-made apparatus, the accessories being crude and rough, but the essentials thoughtfully designed so as to compass in the simplest and most perfect manner the special end in view.
Lord Rayleigh had an interest in abnormal psychological investigations, and became a member and vicepresident of the Society for Psychical Research.
This theory has been supported by the investigations of Dr Klaatsch, of the university of Heidelberg, who would, however, date Australian ancestry still farther back, for his studies on the spot have convinced him that the Australians are " a generalized, not a specialized, type of humanity - that is to say, they are a very primitive people, with more of the common undeveloped characteristics of man, and less of the qualities of the specialized races of civilization."
The fact that a question of which Smith had given the solution in 1867, as a corollary from general formulae governing the whole class of investigations to which it belonged, should have been set by the Academie as the subject of their great prize shows how far in advance of his contemporaries his early researches had carried him.
He was also the author of important papers in which he extended to complex quadratic forms many of Gauss's investigations relating to real quadratic forms. After 1864 he devoted himself chiefly to elliptic functions, and numerous papers on this subject were published by him in the Proc. Lond.
1861), who made important investigations concerning clouds, and attracted attention by his use of kites for obtaining meteorological data.
They number twenty, according to Japanese investigations, and have a coast-line of 174.65 m.
In spite of the investigations of Volkmar and Hilgenfeld, we are still somewhat in the dark as to the authorities he used.
There he began his investigations into the geography, history and antiquities of the district.
His writings include: Mathematical Investigations in the Theory of Value and Prices (1892); Elements of Geometry (with A.
Extending his investigations to the currents produced by batteries, he found that the total voltaic heat generated in any circuit was proportional to the number of electrochemical equivalents electrolysed in each cell multiplied by the electromotive force of the battery.
For a long time the final result deduced by Joule by these varied and careful investigations was accepted as the standard value of the mechanical equivalent of heat.
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.
Of course he does not suppose that his conclusions are in all respects final; but his investigations show that the time has not yet come when a biography of St Francis could be produced answering to the demands of modern historical criticism.
