Amos was throughout life a persistent student, and published various books of importance on legal, constitutional, and literary subjects. His first book was an examination into certain trials in the courts in Canada relative to the destruction of the
Earl of Selkirk's
settlement on the
Red River. It had been alleged that in June 1816 the servants of the
North West Company had destroyed that settlement and murdered Governor Temple and twenty of his people. A few accused persons were brought to trial before the courts of law in
Upper Canada, and they were all acquitted. Amos reproduced and criticised the proceedings at some of these trials, and denounced the state of things as one "to which no British colony had hitherto afforded a parallel, private vengeance arrogating the functions of public law; murder justified in a British court of judicature, on the plea of exasperation commencing years before the sanguinary act; the spirit of monopoly raging in all the terrors of power, in all the force of organisation, in all the insolence of impunity".

De Laudibus Legum Angliæ: The Translation into English Published A.D. MDCCLXXV (1825), which Amos edited In 1825 Amos edited for the
syndics of the University of Cambridge
John Fortescue's
De Laudibus Legum Angliæ, appending the English translation of 1775, and original notes, or rather dissertations, by himself. These notes are full of antiquarian research into the history of English law. His name is familiar in the legal world through the treatise on the
law of fixtures, which he published in concert with Joseph Ferard in 1827 when the law on the subject was wholly unsettled, never having been treated systematically. He found a congenial part of his task to consist in the examination of the legal history of heirlooms, charters, crown jewels, deer, fish, and "things" annexed to the freehold of the church, such as mourning hung in the church, tombstones, pews, organs, and bells. He had shared with
Samuel March Phillipps the task of bringing out a treatise on the law of evidence, and had taken upon himself the whole charge of the preparation of the eighth edition, published in 1838; when, in 1837, he went to India, he had not quite finished the work. In 1846 he wrote
The Great Oyer of Poisoning, an account of the trial of
Robert Carr, 1st Earl of Somerset, for poisoning Sir
Thomas Overbury, a subject bearing on the constitutional aspects of state trials. In the same year he dedicated to his lifelong friend,
William Whewell,
Four Lectures on the Advantages of a Classical Education, as an Auxiliary to a Commercial Education. Among his purely constitutional treatises may be mentioned ''Ruins of Time exemplified in Sir Matthew Hale's Pleas of the Crown
(1856). The object of this was to advocate the adoption of a code of criminal law. In 1857 followed The English Constitution in the Reign of King
Charles the Second, and in 1859 Observations on the Statutes of the Reformation Parliament in the Reign of King Henry the Eighth'', in which he presented a different view of the subject from that of the corresponding chapters of Mr. Froude's History, which had then lately appeared. Among his purely literary works may be mentioned
Gems of Latin Poetry (1851), a collection, with notes, of choice Latin verses of all periods, and illustrating remarkable actions and occurrences, "biography, places, and natural phenomena, the arts, and inscriptions". In 1858 he published
Martial and the Moderns, a translation into English prose of select epigrams of Martial arranged under heads with examples of the uses to which they had been applied. He published various introductory lectures on diverse parts of the laws of England, and pamphlets on various subjects, such as the constitution of the new county courts, the expediency of admitting the testimony of parties to suits, and other measures of legal reform. Amos's political and philosophical convictions were those of an advanced liberalism qualified by a profound knowledge of the constitutional development of the country and of the sole conditions under which the public improvements for which he longed and lived could alone be hopefully attempted. Though he was in constant communication with the leading reformers of his day, and was a candidate for
Kingston upon Hull on the passing of the
Reform Bill in 1832, he concerned himself little at any time with strictly party politics. ==Selected works==
