Rh named in honour of John Fitch, a citizen who did much to secure incorporation; it was chartered as a city in 1872.

FITTIG, RUDOLF (1835–&emsp;&emsp;), German chemist, was born at Hamburg on the 6th of December 1835. He studied chemistry at Göttingen, graduating as Ph.D. with a dissertation on acetone in 1858. He subsequently held several appointments at Göttingen, being privat docent (1860), and extraordinary professor (1870). In 1870 he obtained the chair at Tübingen, and in 1876 that at Strassburg, where the laboratories were erected from his designs. Fittig’s researches are entirely in organic chemistry, and cover an exceptionally wide field. The aldehydes and ketones provided material for his earlier work. He observed that aldehydes and ketones may suffer reduction in neutral, alkaline, and sometimes acid solution to secondary and tertiary glycols, substances which he named pinacones; and also that certain pinacones when distilled with dilute sulphuric acid gave compounds, which he named pinacolines. The unsaturated acids, also received much attention, and he discovered the internal anhydrides of oxyacids, termed lactones. In 1863 he introduced the reaction known by his name. In 1855 Adolph Wurtz had shown that when sodium acted upon alkyl iodides, the alkyl residues combined to form more complex hydrocarbons; Fittig developed this method by showing that a mixture of an aromatic and alkyl haloid, under similar treatment, yielded homologues of benzene. His investigations on Perkin’s reaction led him to an explanation of its mechanism which appeared to be more in accordance with the facts. The question, however, is one of much difficulty, and the exact course of the reaction appears to await solution. These researches incidentally solved the constitution of coumarin, the odoriferous principle of woodruff. Fittig and Erdmann’s observation that phenyl isocrotonic acid readily yielded -naphthol by loss of water was of much importance, since it afforded valuable evidence as to the constitution of naphthalene. They also investigated certain hydrocarbons occurring in the high boiling point fraction of the coal tar distillate and solved the constitution of phenanthrene. We also owe much of our knowledge of the alkaloid piperine to Fittig, who in collaboration with Ira Remsen established its constitution in 1871. Fittig has published two widely used text-books; he edited several editions of Wohler’s Grundriss der organischen Chemie (11th ed., 1887) and wrote an Unorganische Chemie (1st ed., 1872; 3rd, 1882). His researches have been recognized by many scientific societies and institutions, the Royal Society awarding him the Davy medal in 1906.

FITTON, MARY (c. 1578–1647), identified by some writers with the “dark lady” of Shakespeare’s sonnets, was the daughter of Sir Edward Fitton of Gawsworth, Cheshire, and was baptized on the 24th of June 1578. Her elder sister, Anne, married John Newdigate in 1587, in her fourteenth year. About 1595 Mary Fitton became maid of honour to Queen Elizabeth. Her father recommended her to the care of Sir William Knollys, comptroller of the queen’s household, who promised to defend the “innocent lamb” from the “wolfish cruelty and fox-like subtlety of the tame beasts of this place.” Sir William was fifty and already married, but he soon became suitor to Mary Fitton, in hope of the speedy death of the actual Lady Knollys, and appears to have received considerable encouragement. There is no hint in her authenticated biography that she was acquainted with Shakespeare. William Kemp, who was a clown in Shakespeare’s company, dedicated his Nine Daies Wonder to Mistress Anne (perhaps an error for Mary) Fitton, “Maid of Honour to Elizabeth”; and there is a sonnet addressed to her in an anonymous volume, A Woman’s Woorth defended against all the Men in the World (1599). In 1600 Mary Fitton led a dance in court festivities at which William Herbert, later earl of Pembroke, is known to have been present; and shortly afterwards she became his mistress. In February 1601 Pembroke was sent to the Fleet in connexion with this affair, but Mary Fitton, whose child died soon after its birth, appears to have simply been dismissed from court. Mary Fitton seems to have gone to her sister, Lady Newdigate, at Arbury. A second scandal has been fixed on Mary Fitton by George Ormerod, author of History of Cheshire, in a MS. quoted by Mr. T. Tyler (Academy, 27th Sept. 1884). Ormerod asserted, on the strength of the MSS. of Sir Peter Leycester, that she had two illegitimate daughters by Sir Richard Leveson, the friend and correspondent of her sister Anne. He also gives the name of her first husband as Captain Logher, and her second as Captain Polwhele, by whom she had a son and daughter. Polwhele died in 1609 or 1610, about three years after his marriage. But Ormerod was mistaken in the order of Mary Fitton’s husbands, for her second husband, Logher, died in 1636. Her own will, which was proved in 1647, gives her name as “Mary Lougher.” In Gawsworth church there is a painted monument of the Fittons, in which Anne and Mary are represented kneeling behind their mother. It is stated that from what remains of the colouring Mary was a dark woman, which is of course essential to her identification with the lady of the sonnets, but in the portraits at Arbury described by Lady Newdigate-Newdegate in her Gossip from a Muniment Room (1897) she has brown hair and grey eyes.

The identity of the Arbury portrait with Mary Fitton was challenged by Mr Tyler and by Dr Furnivall. For an answer to their remarks see an appendix by C. G. O. Bridgeman in the 2nd edition of Lady Newdigate-Newdegate’s book.

The suggestion that Mary Fitton should be regarded as the false mistress of Shakespeare’s sonnets rests on a very thin chain of reasoning, and by no means follows on the acceptance of the theory that William Herbert was the addressee of the sonnets, though it of course fails with the rejection of that supposition. Mr William Archer (Fortnightly Review, December 1897) found some support for Mary Fitton’s identification with the “dark lady” in the fact that Sir William Knollys was also her suitor, thus numbering three “Wills” among her admirers. This supplies a definite interpretation, whether right or wrong, to the initial lines of Sonnet 135:— Arguments in favour of her adoption into the Shakespeare circle will be found in Mr Thomas Tyler’s Shakespeare’s Sonnets (1890, pp. 73-92), and in the same writer’s Herbert-Fitton Theory of Shakespeare’s Sonnets (1898).

FITTON, WILLIAM HENRY (1780–1861), British geologist was born in Dublin in January 1780. Educated at Trinity College, in that city, he gained the senior scholarship in 1798, and graduated in the following year. At this time he began to take interest in geology and to form a collection of fossils. Having adopted the medical profession he proceeded in 1808 to Edinburgh, where he attended the lectures of Robert Jameson, and thenceforth his interest in natural history and especially in geology steadily increased. He removed to London in 1809, where he further studied medicine and chemistry. In 1811 he brought before the Geological Society of London a description of the geological structure of the vicinity of Dublin, with an account of some rare minerals found in Ireland. He took a medical practice at Northampton in 1812, and for some years the duties of his profession engrossed his time. He was admitted M.D. at Cambridge in 1816. In 1820, having married a lady of means, he settled in London, and devoted himself to the science of geology with such assiduity and thoroughness that he soon became a leading authority, and in the end, as Murchison said, “one of the British worthies who have raised modern geology to its present advanced position.” His “Observations on some of the Strata between the Chalk and the Oxford Oolite, in the South-east of England” (Trans. Geol. Soc. ser. 2, vol. iv.) embodied a series of researches extending from 1824 to 1836, and form the classic memoir familiarly known as Fitton’s “Strata below the Chalk.” In this great work he established the true succession and relations of the Upper and Lower Greensand, and of the Wealden and Purbeck formations, and elaborated their detailed structure. He had been elected F.R.S. in 1815, and he was president of the Geological Society of London 1827–1829. His house then became a meeting place for scientific workers, and during his presidency he held a conversazione open on Sunday evenings to all fellows of the Geological Society. From 1817 to 1841 he contributed to the Edinburgh Review many admirable essays on the progress of geological science; he also wrote “Notes on the
