wrought upon the sterner nature of his colleague that, when Sir 

 James left for Europe two years ago, the parting was a severe trial 

 to Mr. Lutwyche, who was extremely affected at bidding good-bye 

 to a friend whom he rightly divined he was never to see again." 



The Chief Justice was Senior Commissioner for the consolidation 

 (effected in 1867) of the statute law of Queensland. He was 

 knighted by patent in 1869. In 187-4 the Legislative Assembly of 

 Queensland showed their appreciation of his services by passing an 

 Act giving him a substantial increase of salary. 



Sir James Cockle's professional occupations at this period were 

 numerous and exacting, yet he did not neglect his favourite science. 

 He turned to mathematics as a relaxation, and devoted the intervals 

 of official labour to researches in algebra and differential equations, 

 embodying his results in papers which appeared from time to time 

 in the ' Manchester Memoirs,' the ' Quarterly Journal of Mathe- 

 matics,' the ' Philosophical Magazine,' and other periodicals in 

 England, and in the ' Proceedings ' of the Royal Societies of New 

 South Wales and Victoria, in Australia. He also wrote and pub- 

 lished a number of presidential addresses delivered before the 

 Queensland Philosophical Society (now incorporated into the Royal 

 Society of Queensland) in which he dealt with questions in philo- 

 sophy, logic, and mathematics. 



In 1879 he resigned his position as Chief Justice of Queensland, 

 having a few months before returned to England with his wife and 

 children. The remainder of his days was given to mathematical 

 writing, the businees of several learned bodies, and the society of 

 his friends ; but he was never really strong after his return home, 

 his health suffering perhaps from the change of climate. 



He was elected a Fellow of the Royal Astronomical Society in 

 1854, and served on its Council from 1888 to 1892. He was elected a 

 Fellow of the Royal Society in 1865, a Corresponding Member of the 

 Manchester Literary and Philosophical Society, and a Member of the 

 London Mathematical Society in 1870 ; he filled the Presidential 

 Chair of the latter Society from 1886 to 1888. He was President of 

 the Queensland Philosophical Society from 1863 to 1879, and was 

 elected an Honorary Member of the Royal Society of New South 

 Wales in 1876. He was a Commissioner for the Queensland Section 

 of the Colonial and Indian Exhibition held in London in 1886 ; and 

 was nominated to represent the Australian Colonies at the Washing- 

 ton Prime Meridian Conference in 1884, but was unable to accept the 

 position. 



Of his personal and social qualities the writer may be permitted 

 to speak from personal knowledge. He looks back with pleasure to 

 an acquaintance begun nearly fifty years ago, which soon ripened 

 into a friendship, never clouded even for a moment by the slightest
