derivatives, on nitrogen chlorophosphide, on the so-called nitrogen 

 iodides, and on pyrophosphoric acid and its amides, mostly alone, but 

 partly in conjunction with Mr. J. D. Holmes. After Mr. Holmes' 

 death, he worked in collaboration with Mr. Alfred Tribe. The 

 discovery of the copper-zinc couple in 1872, and the study of its action 

 on organic substances, constitute, perhaps, the most important result 

 of this co-operation. For these researches he was awarded, in 1897, 

 the Davy Medal. 



Dr. Gladstone was well acquainted with Faraday. Indeed, there 

 was much in common between the two men, and their intimacy 

 developed into a firm and lasting friendship. After Faraday's death, 

 Dr. Gladstone put together his reminiscences of his friend in the form 

 of a biographical notice, " The Biography of Michael Faraday, London, 

 1872," which was one of the most popular and most widely read 

 accounts of the career of that illustrious philosopher. 



Although ardently attached to science, and keenly interested in its 

 progress, much of Dr. Gladstone's intellectual energy was spent in 

 other pursuits. Throughout the whole of his life he was engaged in 

 philanthropic, educational, and religious movements. Very early in 

 his career he became connected with the British and Foreign School 

 Society, and soon after the formation of the Young Men's Christian 

 Association he joined the parent Society, and served on the Committee 

 for some years, and when the first World's Conference met in Paris in 

 1855, he was one of the representatives of the London Associations, 

 and also at the first British Conference, held at Leeds in 1858. He 

 was a Vice-President of the National Council from the time of its 

 formation, and took a great interest in its work at home and 

 abroad. 



Members of the British Association for the Advancement of Science 

 will remember that Dr. Gladstone, who was a constant attendant at 

 its gatherings, annually convened a religious meeting, as a practical 

 expression of his views concerning the relation of science to religion. 

 As a Member of the Christian Evidence Society, in whose work he 

 continued to take the liveliest interest to the very day of his death, 

 he published two lectures, one on " Points of Supposed Collision 

 between the Scriptures and Natural Science," and the second, on 

 " Miracles as Credentials of a Revelation." 



Dr. Gladstone, who was an ardent Liberal in politics, was frequently 

 solicited to enter Parliament, and in 1868 he unsuccessfully contested 

 the borough of York. If returned, he had intended to throw himself 

 into the educational struggle which was to culminate in the passage of 

 Mr. Forster's measure in 1870. Indeed, he will long be remembered 

 for his services to the cause of education. 



From 1873 to 1894 he was a Member of the School Board for
