of the Royal Society on 7 June 1860 and was a fellow of the Royal Society of Edinburgh, the Royal Geographical Society, the Geological Society, the Society of Arts, and the Royal Institution. Early works In 1834 Bateman investigated the causes of flooding on the River Medlock, which led to a study of hydraulic engineering. In 1835, in association with Sir William Fairbairn, he laid out the reservoirs on the River Bann in Ireland. From that time he was almost continually employed in the construction of reservoirs and waterworks. In all his undertakings he advocated soft water in preference to hard, and favoured gravitation schemes where they were practicable to avoid the necessity of pumping. He devoted much attention to methods of measuring rainfall, accumulated a quantity of statistics on the subject, and wrote several papers describing his observations. Manchester water supply The greatest waterworks project undertaken by Bateman was that connected with supplying water to Manchester and Salford from a chain of reservoirs in Longdendale. He was consulted about such a scheme in 1844 and by 1846 had devised ta project for obtaining water from the Pennine hills. Work commenced in 1848 and was not finished until spring 1877. The Longdendale Chain scheme was designed to supply a population less than half that of Manchester in 1882, and additional sources of supply had to be found. At Bateman's suggestion the corporation decided to extract water from Thirlmere in the Lake District. A bill introduced into parliament in 1878 was rejected but passed in 1879. Bateman superintended the works, assisted by George Hill. In 1884 Bateman published a History and Description of the Manchester Waterworks. Loch Katrine and Milngavie waterworks In 1852 Bateman was consulted by Glasgow Council in regard to its water supply. In 1854–85, on Bateman's advice, a bill was obtained to supply water to Glasgow from Loch Katrine. Work commenced in spring 1856 and was completed by March 1860. The works extend over 34 miles, and were described by James Morris Gale as worthy to "bear comparison with the most extensive aqueducts in the world, not excluding those of ancient Rome". Other works In 1855 he wrote a paper for the British Association, On the present state of our Knowledge on the Supply of Water to Towns, enunciating the nature of the problem, outlining previous measures, enumerating sources from which towns could be supplied, and discussing their
