sary, and the professor, with characteristic liberality, lost no opportunity of increasing the collection at his own expense. In 1866 he resigned the professorship, the duties of which had for some years been discharged by a deputy, on the creation of a second chair of zoology and comparative anatomy, a scheme which he had pressed upon the university commission in 1852, thinking it desirable that the two chairs should be filled simultaneously.
Clark took holy orders in 1818, and in 1824 was presented by the master and fellows of his college to the small vicarage of Arrington in Cambridgeshire. This he exchanged in the following year for the vicarage of Wymeswold in Leicestershire. Neither of these pieces of preferment entailed residence. In 1826 he was presented by the same society to the valuable rectory of Guiseley, near Leeds. Though nonresident, except for about three months, on an average, in each year, he kept a watchful eye on all that was going forward in the parish, took infinite pains to select a really good curate, restored the church, built schools, made the rectory-house habitable, and in all ways allowed his zeal for the place. He held this living until 1869, when failing health compelled him to resign it. He died on 15 Sept. 1869. He married in 1827 Mary, daughter of Robert Darling Willis, M.D., by whom he left one son.
Besides the 'Analysis of a Course of Lectures on the Anatomy and Physiology of the Human Body' (1822), above referred to, Clark published: 'A Case of Human Monstrosity, with a Commentary,' in the 'Trans. Camb. Phil. Soc.' (1831); 'Report on Animal Physiology,' 1834, in the 'Trans. Brit. Assoc.;' a 'Handbook of Zoology,' translated from the Dutch of J. Van der Hoeveu (1856-8); and 'Catalogue of the Osteological Portion of Specimens contained in the Anatomical Museum of the University of Cambridge,' 1802.

CLARK, WILLIAM (1821–1880), civil engineer and inventor, was born at Colchester, 17 March 1821. He went to King's College, London, in 1842, and was elected an associate of the college in 1845. Soon afterwards he became a pupil of, and subsequently an assistant to, J. Birkinshaw, M. Inst. C.E., under whom he was employed for three years on the works of the York and North Midland railway system. In 1850 he was connected with Sir Goldsworthy Gurney in the warming and ventilation of the houses of parliament. In 1851 he entered into partnership with A. W. Makinson, M. Inst. C.E., the firm devoting special attention to the warming and ventilating of public buildings. He shortly afterwards obtained the appointment of surveyor to the local board of health of Kingston-upon-Hull, and devised a complete system of drainage for that town. In 1854 he entered the service of the East Indian Railway Company, and, after acting for a year as resident engineer on a portion of the East India railway, became the secretary and subsequently the engineer to the municipality of Calcutta. Clark devoted himself with zeal to his work, and very soon proposed a complete scheme for the drainage of the city, only imperfectly carried out owing to the expense. He also devised a system of waterworks, comprising three large pumping stations, with their filter beds and settling tanks. He returned to England in 1874, when he entered into partnership with W. F. Batho, M. Inst. C.E., and in the same year received the appointment of consulting engineer to the Oudh and Rohilkund Railway Company. In December 1874 he visited Madras, where he remained four months planning a system of drainage for that city. He was selected by the colonial office in 1876, in concert with the government of New South Wales, to advise and report upon the water supply and drainage of Sydney. During a residence of two years in the Australian colonies he prepared schemes of a like description for Port Adelaide, Newcastle, Bathurst, Goulburn, Orange, Maitland, and Brisbane, and afterwards for Wellington and Christchurch in New Zealand. Among Clark's inventions was his tied brick arch, of which examples exist in Calcutta and in other places in India; and he was joint patentee with Batho of the well-known steam road roller. Among his schemes was a proposal for reclaiming the salt-water lakes in the neighbourhood of Calcutta. He was elected a member of the Institution of Civil Engineers 2 Feb. 1864, and a member of the Institution of Mechanical Engineers in 1867. He died from an affection of the liver, at Surbiton, 22 Jan. 1880. He was the writer of ‘The Drainage of Calcutta,’ 1871.
