"Although it would seem as if we had already furnished sufficient proofs that modern science has little or no reason to boast of originality, yet before closing this volume we will adduce a few more to place the matter beyond doubt... In the famous and recent work of Christna et le Christ, we find the following tabulation: [...]"Mathematics.--They invented the decimal system, algebra, the differential, integral, and infinitesimal calculi. They also discovered geometry and trigonometry, and in these two sciences they constructed and proved theorems which were only discovered in Europe as late as the seventeenth and eighteenth centuries[...] [...]"Chemistry.--They knew the composition of water, and formulated for gases the famous law, which we know only from yesterday, that the volumes of gas are in inverse ratio to the pressures that they support. They knew how to prepare sulphuric, nitric, and muriatic acids; the oxides of copper, iron, lead, tin, and zinc; the sulphurets of iron, copper, mercury, antimony, and arsenic; the sulphates of zinc and iron; the carbonates of iron, lead, and soda; nitrate of silver; and powder. "Medicine.--Their knowledge was truly astonishing. In Tcharaka and Sousruta, the two princes of Hindu medicine, is laid down the system which Hippocrates appropriated later. Sousruta notably enunciates the principles of preventive medicine or hygiene, which he places much above curative medicine--too often, according to him, empyrical. Are we more advanced to-day? It is not without interest to remark that the Arab physicians, who enjoyed a merited celebrity in the middle ages--Averroes among others--constantly spoke of the Hindu physicians, and regarded them as the initiators of the Greeks and themselves. [...]"Surgery.--In this they are not less remarkable. They made the operation for the stone, succeeded admirably in the operation for cataract, and the extraction of the foetus, of which all the unusual or dangerous cases are described by Tcharaka with an extraordinary scientific accuracy. [...]"Architecture.--They seem to have exhausted all that the genius of man is capable of conceiving. Domes, inexpressibly bold; tapering cupolas; minarets, with marble lace; Gothic towers; Greek hemicycles; polychrome style--all kinds and all epochs are there, betokening the origin and date of the different colonies, which, in emigrating, carried with them their souvenirs of their native art." Such were the results attained by this ancient and imposing Brahmanical civilization.... Beside the discoverers of geometry and algebra, the constructors of human speech, the parents of philosophy, the primal expounders of religion, the adepts in psychological and physical science, how even the greatest of our biologists and theologians seem dwarfed! Name to us any modern discovery, and we venture to say, that Indian history need not long be searched before the prototype will be found of record."
