rations and extensions of many private mansions. Among his works, the 

 single-arched iron bridge over the River Cam, at St. John's College, Cam- 

 bridge, has been much admired ; and the church of St. Mark's, Clerken- 

 well, met with considerable approval at the period of its erection, forty 

 years since. 



Mr. Mylne in later years was much occupied in Government references, 

 and acted as surveyor for fifty years to the Stationers' Company, having 

 succeeded his father in that office. He was also extensively engaged 

 before Parliamentary Committees on Water, Dock, and Drainage Works, 

 and was consulted in continental works of similar character. 



From the date of his entering on the direction of the New River Works 

 to his retirement, two years before his death a period of fifty years he 

 had the satisfaction to witness a very great advance in the income of the 

 Company, and a great extension of their works, consequent on the increased 

 demand caused by the further growth of the metropolis and awakened 

 attention to its salubrity. In 1852 new works were undertaken to the 

 extent of three quarters of a million sterling, and executed by him, with 

 the assistance of his son, R. W. Mylne, F.R.S. 



Mr. Mylne was a man of a peculiarly kind and conciliatory disposition, 

 a peace-maker in all professional strife, of strict integrity and high honou- 

 rable feeling. He was for many years the guiding hand, as Treasurer, to the 

 Society of Engineers styled " Smeatonians," in which, as in all other Asso- 

 ciations, he won the respect, esteem, and almost affection of those with 

 whom he was connected. His retiring disposition caused him seldom to 

 take part in scientific discussions ; but he took a keen interest in all ques- 

 tions of progress, and during his long career judiciously availed himself 

 of the opportunities offered him of adopting the new inventions of the age. 



Mr. Mylne was elected a Fellow of the Royal Society on the 16th of 

 March, 1826. 



Major-General JOSEPH ELLISON PORTLOCK, son of Captain Nathaniel 

 Portlock, a distinguished officer of the Royal Navy, was born at Gosport 

 in September 1/94. He received his early education at a school in his 

 native town and at Tiverton, from which he went to the Royal Military 

 Academy at Woolwich. In 1813 he took his first commission in the 

 Royal Engineers, and was sent in the following year to Canada, where he 

 remained actively employed in military service or exploring expeditions 

 until 1822. He was present at the siege of Fort Erie ; and, on the retire- 

 ment of the troops, he constructed the lines and bridge-head at Chippewa, 

 at which Sir Gordon Drummond made his successful stand, and saved 

 Upper Canada. 



In 1824, on the extension of the Ordnance Survey to Ireland, Lieut. 

 Portlock was one of the officers first selected by Colonel Colby to take part 

 in the work ; and his earliest duty in connexion therewith, conjointly with 

 Lieuts. Drummond and Larcom, lay in working out the preliminaries of
