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 be considered to possess a permanent value. Herschel was delighted with his own share. He writes to Whewell, thanking him for ‘the splendid review,’ and declaring that he ‘should have envied the author of any work, if a stranger, which could give occasion for such a review.’ Lyell wrote in much the same strain; and we are rather surprised that he did so; for his reviewer not only stubbornly refused to accept his theory of uniformity of action, in opposition to the cataclysmic views of the Huttonians, but treated the whole question in a spirit of good-humoured banter, in which even Herschel thought that he had gone too far. The article on his friend Mr Jones’ work—which appeared in the _British Critic_—is rather an exposition of his views, which were original, than a criticism. It was Whewell’s first appearance in print on any question of political economy, except a short memoir in the Transactions of the Cambridge Philosophical Society, called a _Mathematical Exposition of some Doctrines of Political Economy_; and therefore marks a period when he had added yet one more science to those which he had already mastered. In this year he gave much time to a controversy which was agitating the University on the question of the best plans to be adopted for a new Public Library; and contributed a bulky pamphlet to the literature of the subject, in opposition to his friend Mr Peacock. The whole question is a very interesting one; but our space will not allow us to do more than mention it, as another instance of the diversity of Whewell’s interests.
The next year (1832) was even a busier one than its predecessor; he was occupied in revising some of his mathematical text-books; in drawing up a Report on Mineralogy for the British Association, described as ‘an example of the unrivalled power with which he mastered a subject with which his previous studies had had but little connexion’; and in writing one of the Bridgewater Treatises, a work which, with most men, would have been enough to occupy them fully during the whole of the three years which had elapsed since the President of the Royal Society had selected him as one of the eight writers who should carry out the intentions of the Earl of Bridgewater. The subject of his treatise is _Astronomy and General Physics considered with reference to Natural Theology_. It is one of Whewell’s most thoughtful and justly celebrated works, on which he must have bestowed much time. During the intervals, however, of its composition, he had not only written the reviews we have mentioned, and others also, to which we can only allude, but had commenced those researches on the Tides, which are embodied in no fewer than fourteen memoirs in the Transactions of the Royal Society, and for which he afterwards received the Royal Medal. No wonder that even he began to feel overworked, and resigned the Professorship of Mineralogy early in the year. He writes to his friend Mr Jones, whom he was always striving to inspire with some of his own restless activity of thought and composition:
