coal, and in 1846 he issued a "Plan of part of the Yorkshire 

 Coalfield.' He reported (1863) on M. de Lesseps's proposed Suez 

 Canal, and his report, which contains numerous observations of 

 geological interest, decided Said Pasha in favour of the scheme. 

 Prom 1862 until its completion in 1871, he was engineer to the 

 Amsterdam Ship Canal, the most important work of its kind now 

 completed, with the exception of the Suez Canal. 



His professional avocations led him to plan or report upon many- 

 engineering projects involving some acquaintance with geological 

 structure, such as water-supply, arterial drainage, canalization, 

 docks, harbours, and the improvement of river-channels. 



Sir J. Hawkshaw was Consulting Engineer for the Severn Tunnel. 

 When great trouble arose from the enormous quantities of water 

 met with, he was appointed Chief Engineer, and under his direction 

 the work was successfully completed. The Brighton Intercepting 

 Sewer, 7 miles long, was also a work of his in which considerabh^ 

 quantities of water had to be encountered. 



To the general public he became well known from his advocacy 

 of the Channel Tunnel. In 1865 he employed Mr. H. Day to make 

 a detailed geological survey of the shores of the adjacent country, 

 and Mr. H. M. Erunel to ascertain the nature of the bottom and 

 the outcrops of strata under the sea. Puller investigations were 

 afterwards undertaken by the Erench engineers, and still later by 

 the South Eastern Eailway. Whilst fully convinced of the feasi- 

 bility of the scheme from an engineering point of view. Sir J. Hawk- 

 shaw in later years was much impressed by the military and political 

 objections urged against it, and he ultimately declined to take 

 further part in the work. 



In 1836 Sir John became an Associate of the Institute of Civil 

 Engineers, and in 1838 was elected Member. He was President of 

 the Institution in 1861, was knighted in 1873, and was President 

 of the British Association in 1875. He was elected a Eellow of 

 this Society in 1837, and of the Eoyal Society in 1855. 



The name of S. Collett Homeesham will be chiefly remembered 

 by geologists for his services in connexion with the deep boring for 

 water at Eichmond. Under his father, who was engineer to the 

 Eichmond Waterworks, he devoted himself with great enthusiasm 

 and care to the preservation of specimens of all the rocks passed 

 through in the operations, and by so doing provided a body of infor- 

 mation such as exists in the case of no other deep boring in the
