The narrative presents a number of difficulties, which early commentators sought to solve with more ingenuity than success.
He has applied the theory with especial ingenuity to the interpretation of the circular bony plates in the carapace of the aberrant leather-back sea-turtles (Sphargidae) by prefacing an initial land phase, in which the typical armature of land tortoises was acquired, a first marine or pelagic phase, in which this armature was lost, a third littoral or seashore phase, in which a new polygonal armature was acquired, and a fourth resumed or secondary marine phase, in which this polygonal armature began to degenerate.
The peasants are described as intelligent, and the artizans are justly celebrated for their ingenuity and mechanical skill.
Ampere, Wollaston and others, the realization of the continuous rotation of the wire and the magnet round each other was a scientific puzzle requiring no mean ingenuity for its original solution.
All these might pass for religious wars, and they might really be so; it needed greater ingenuity to set forth the invasion of England as a missionary enterprise designed for the spiritual good of the benighted islanders.
But in his mode of forming ridges his practice seems to have been original; his implements, especially his drill, display much ingenuity; and his claim to the title of founder of the present horse-hoeing husbandry of Great Britain seems indisputable.
There are various systems of purging refined, or socalled refined, sugar in centrifugals, all designed with a view of obtaining the sugar in lumps or tablets, so as to appear as if it had been turned out from moulds and not from centrifugals, and great ingenuity and large sums of money have been spent in perfecting these different systems, with more or less happy results.
Mag., 1868, 35, p. 161, and the full account, which serves as an excellent example of the extraordinary care and ingenuity of Regnault's work, is given in the Memoires de l'academie des sciences, 1868, xxxvii.
The ingenuity of nature, however, in adapting animals is not infinite, because the same devices are repeatedly employed by her to accomplish the same adaptive ends whether in fishes, reptiles, birds or mammals; thus she has repeated herself at least twenty-four times in the evolution of long-snouted rapacious swimming types of animals.
Another series of instruments, introduced by Cooke and Wheatstone in 1840, and generally known as " Wheatstone's step-by-step letter-showing " or " ABC instruments," were worked out with great ingenuity of detail by Wheatstone in Great Britain and by Breguet and others in France.
His connexion with the university was made memorable by his defence of the doctrine of the Immaculate Conception, in which he displayed such dialectical ingenuity as to win for himself the title Doctor Subtilis.
Terada in a research remarkable for its completeness and the ingenuity of the experimental methods employed.
In like manner, after the French mathematicians had attempted, with more or less ingenuity, to construct a theory of elastic solids from the hypothesis that they consist of atoms in equilibrium under the action of their mutual forces, Stokes and others showed that all the results of this hypothesis, so far at least as they agreed with facts, might be deduced from the postulate that elastic bodies exist, and from the hypothesis that the smallest portions into which we can divide them are sensibly homogeneous.
The technical services, in which the mechanical skill and ingenuity of the American had full play, developed remarkable efficiency.
Other works are A Discourse concerning a New Planet (1640); Mercury, or the Secret and Swift Messenger (1641), a work of some ingenuity on the means of rapid correspondence; and Mathematical Magick (1648).
Before Lightfoot's time commentaries, especially on the epistles, had not infrequently consisted either of short homilies on particular portions of the text, or of endeavours to enforce foregone conclusions, or of attempts to decide with infinite industry and ingenuity between the interpretations of former commentators.
