at the feet of Professor Mohs, of Freiburg: a subject on which he had already made communications to the Royal Society and to the Cambridge Philosophical Society. This was his first introduction to Germany, in whose language and literature he thenceforward took the greatest interest. He even modified his way of writing English in accordance with German custom, as is shown by the plentiful scattering of capitals through his sentences, and by a certain ponderosity of style which savours of German originals. The dissensions as to the mode of election to the Mineralogical chair caused it to remain vacant for three years; so that Whewell, about the choice of whom there never seems to have been any doubt, had no immediate opportunity of turning to account his newly-acquired knowledge. He therefore, with even more than characteristic energy, turned his attention to two most opposite subjects, Theology, and the Density of the Earth.

      In the summer of 1826 he commenced a series of investigations on the latter subject at Dolcoath Mine, Cornwall, in conjunction with Mr. Airy. The essential part of the process was to compare the time of vibration of a pendulum at the surface of the earth with the time of vibration of the same pendulum at a considerable depth below the surface. Unfortunately the experiments, which were renewed in 1828, failed to lead to any satisfactory result, partly through an error in the construction of the pendulum, partly through a singular fatality, by which, on both occasions, they were frustrated by a serious accident. The account he gives of himself, and of the way in which the researches were regarded by the Cornishmen, is too amusing not to be quoted. It is contained in a letter to his friend Lady Malcolm, and is dated ‘Underground Chamber, Dolcoath Mine, Camborne, Cornwall, June 10, 1826:

      ‘I venture to suppose that you never had a correspondent who at the time of writing was situated as your present one is. I am at this moment sitting in a small cavern deep in the recesses of the earth, separated by 1,200 feet of rock from the surface on which you mortals tread. I am close to a wooden partition which has been fixed here by human hands, through which I ever and anon look, by means of two telescopes, into a larger cavern. That larger den has got various strange-looking machines, illumined here and there by unseen lamps, among which is visible a clock with a face most unlike common clocks, and a brass bar which swings to and fro with a small but never-ceasing motion. I am clad in the garb of a miner, which is probably more dirty and scanty than anything you may have happened to see in the way of dress. The stillness of this subterranean solitude is interrupted by the noise, most strange to its walls, of the ticking of my clock, and the chirping of seven watches. But besides these sounds it has noises of its own which my ear catches now and then. A huge iron vessel is every quarter of an hour let down through the rock by a chain above a thousand feet long, and in its descent and ascent dashes itself against the sides of the pit with a violence and a din like thunder; and at intervals, louder and deeper still, I hear the heavy burst of an explosion when gunpowder has been used to rend the rock, which seems to pervade every part of the earth like the noise of a huge gong, and to shake the air within my prison. I have sat here for some hours, and shall sit five or six more, at the end of which time I shall climb up to the light of the sky in which you live, by about sixty ladders, which form the weary upward path from hence to your world. I ought not to omit, by way of completing the picturesque, that I have a barrel of porter close to my elbow, and a miner stretched on the granite at my feet, whose yawns at being kept here so many hours, watching my inscrutable proceedings, are most pathetic. This has been my situation and employment every day for some time, and will be so for some while longer, with the alternation of putting myself in a situation as much as possible similar, in a small hut on the surface of the earth. Is not this a curious way of spending one’s leisure time? I assure you I often think of Sir John’s favourite quotation from Leyden, “Slave of the dark and dirty mine! What vanity has brought thee here?” and sometimes doubt whether sunshine be not better than science.

      ‘If the object of my companion and myself had been to make a sensation, we must have been highly gratified by the impression which we have produced upon the good people in this country. There is no end to the number and oddity of their conjectures and stories about us. The most charitable of them take us to be fortune-tellers; but for the greater part we are suspected of more mischievous kinds of magic. A single loud, insulated, peal of thunder, which was heard the first Sunday after our arrival, was laid at our door; and a staff which we had occasion to plant at the top of the cliff, was reported to have the effect of sinking all unfortunate ships which sailed past.

      ‘I could tell you many more such histories; but I think this must be at least enough about myself, if I do not wish to make the quotation from Leyden particularly applicable.’

      Whewell had been ordained priest on Trinity Sunday, 1826, and this circumstance had probably directed him to a more exact study of theology than he had previously attempted. The result was a course of four sermons before the University in February 1827. The subject of these, which have never been printed, may be described as the ‘Relation of Human to Divine Knowledge.’ They attracted considerable attention when delivered; and it was even suggested that the author ought to devote himself to theology as a profession, and try to obtain one of the Divinity Professorships; but the advice was not taken. A theological tone may, however, be observed in most of his scientific works; he loved to point out analogies between scientific and moral truths, and to show that there was no real antagonism between science and revealed religion.

      In 1828 the new Professor of Mineralogy entered upon his functions, and after his manner rushed into print with an Essay on Mineralogical Classification and Nomenclature, in which there is much novelty of definition and arrangement. He was conscious that he had been somewhat precipitate; for he writes to his friend, Mr. Jones, who was trying to make up his mind on certain problems of political economy, and declined to print until he had done so:

      ‘I avoid all your anxieties about authorship by playing for lower stakes of labour and reputation. While you work for years in the elaboration of slowly-growing ideas, I take the first buds of thought and make a nosegay of them without trying what patience and labour might do in ripening and perfecting them^[3].’

      At the beginning of the year 1830 there appeared an anonymous publication entitled Architectural Notes on German Churches, with Remarks on the Origin of Gothic Architecture. The author need not have tried to conceal his name; in this, as in other similar attempts, his style betrayed his identity at once. The work went through three editions, in each of which it was characteristically altered and enlarged, so that what had appeared as an essay of 118 pages in 1830, was transformed into a work of 348 pages in 1842. Architecture had been from the first one of Whewell’s favourite studies. In a letter to his sister in 1818 he speaks of a visit to Lichfield and Chester for the purpose of studying their cathedrals; many of his subsequent tours were undertaken for similar objects; and his numerous note-books and sketch-books (for he was no mean draughtsman) contain ample evidence of the pains he bestowed on perfecting himself in architectural details. The theory, or ‘ground-idea,’ as his favourite Germans would have called it, which he puts forward, is, that the pointed arch, even if it was really introduced from the East, which he evidently doubts, was improved and developed through the system of vaulting, which the Gothic builders learnt from the Romans. This theory has not been generally accepted; but the mere statement of it may have been of value, as the author suggests, ‘in the way of bringing into view relations and connexions which really exerted a powerful influence on the progress of architecture’; and the sketch of the differences between the classical and the Gothic styles is certainly extremely good. It has been sometimes suggested that the whole book was written in a spirit of rivalry to the Remarks on the Architecture of the Middle Ages, by Professor Willis. A glance at the dates of publication is enough to refute this view; for the work of Professor Willis was published in 1835, the first edition of Dr. Whewell’s in 1830. In the course of this summer he made an architectural tour with Mr. Rickman in Devon and Cornwall; and, as if in order that his occupations might be as sharply contrasted as possible, investigated also the geology of the neighbourhood of Bath.

      In 1831 we find Whewell reviewing three remarkable books: Herschel’s Discourse on the Study of Natural Philosophy; Lyell’s Principles of Geology, vol. i.; and Jones On the Distribution of Wealth. As Mr. Todhunter remarks, scarcely any person but himself could have ventured on such a task. These reviews are not merely critical; they contain much of the author’s own speculations, much that went beyond the interest of the moment, and might
