Brown-Sequard records an instance produced by injury to the sciatic nerve. Doyle gives an account of the production of epilepsy from protracted bathing in a pond. Duncan cites an instance of epilepsy connected with vesical calculus that was cured by lithotomy. Museroft mentions an analogous case. Greenhow speaks of epilepsy arising from an injury to the thumb. Garmannus, early in the eighteenth century, describes epilepsy arising from fright and terror. Bristowe in 1880, and Farre speak of similar instances. In Farre's case the disease was temporarily cured by an attack of acute rheumatism.英文原著 · 《Anomalies and Curiosities of Medicine》
In order to realise the magnitude of the revolution which Hamilton has wrought in the application of symbols to mathematical investigation, it is necessary to think of what Hamilton did beside the mighty advance made by Descartes. To describe the character of the quaternion calculus would be unsuited to the pages of this work, but we may quote an interesting letter, written by Hamilton from his deathbed, twenty-two years later, to his son Archibald, in which he has recorded the circumstances of the discovery:--英文原著 · 《Great Astronomers》
It was ten years after the discovery that the great volume appeared under the title of "Lectures on Quaternions," Dublin, 1853. The reception of this work by the scientific world was such as might have been expected from the extraordinary reputation of its author, and the novelty and importance of the new calculus. His valued friend, Sir John Herschel, writes to him in that style of which he was a master:--英文原著 · 《Great Astronomers》
In 1858 a correspondence on the subject of Quaternions commenced between Professor Tait and Sir William Hamilton. It was particularly gratifying to the discoverer that so competent a mathematician as Professor Tait should have made himself acquainted with the new calculus. It is, of course, well known that Professor Tait subsequently brought out a most valuable elementary treatise on Quaternions, to which those who are anxious to become acquainted with the subject will often turn in preference to the tremendous work of Hamilton.英文原著 · 《Great Astronomers》
Alike for the memory of Hamilton, for the credit of his University, and for the benefit of science, let us hope that a collected edition of his works will ere long appear--a collection which shall show those early achievements in splendid optical theory, those achievements of his more mature powers which made him the Lagrange of his country, and finally those creations of the Quaternion Calculus by which new capabilities have been bestowed on the human intellect.英文原著 · 《Great Astronomers》
