Jan.. 1894. TYNDALL. II 



ment as one of the Civil Assistants in the Ordnance Survey, and was 

 at first quartered at Carlow. He was, however, soon moved to Lanca- 

 shire, and then continued his studies at the evening classes of the 

 Mechanics' Institute at Preston ; he at this time intended to become 

 a civil engineer, and contemplated emigrating to America. Some 

 experiments, however, which he saw one evening during a lecture at 

 Preston, roused in him a keen interest in pure science apart from its 

 practical applications. 



He remained on the Ordnance Survey for five years and, as he 

 had had experience of most branches of the work, became a well- 

 trained surveyor. When the railway mania burst upon the country, 

 this meant money, and Tyndall in 1844 entered the employment of a 

 Manchester firm ; for three years he was kept very hard at work on 

 various surveys, but the excitement and strain and wild unrest of 

 this life were too much for him. He had saved about three hundred 

 pounds, so he threw up his appointment and in 1847 joined the staft 

 of Queenswood College in Hampshire. 



This step was probably induced not so much by the fact that the 

 toil of the railway survey was too severe : he had no interest in the 

 work : he was never avaricious and he had already come to feel an 

 enthusiasm for science and had fallen under the influence of Carlyle. 

 He had intended to devote his leisure here to research, but he felt the 

 need of further scientific education before he could seriously commence 

 this. In company, therefore, with his friend and colleague, Dr. Edward 

 Frankland, he left England in 1848. 



It was probably due to the teaching of Carlyle that they decided 

 to study in Germany, and there the fame of Bunsen drew them 

 both to Marburg. There they studied chemistry under the great 

 master, and worked at physics under Gerling and Knoblauch. With 

 the latter he wrote one of his earliest papers, " On the Deportment of 

 Crystalline Bodies between the Poles of a Magnet," which was pub- 

 lished in the Philosophical Magazine for 1850, and was republished in 

 the Annales de Chemie, the Archives of the Bibliotheque Universelle, and 

 Poggendorf 's Annalen. At the same time he was a constant reader 

 of Carlyle ; and Tyndall has himself told us that it was thus he 

 derived the inspiration which kept him hard at work, and made him 

 face his early morning tub through the cold of a German winter. 



From Hesse-Cassell Tyndall moved to Berlin, where he worked 

 at diamagnetism in the laboratory of Professor Magnus, and gained the 

 friendship of Helmholtz and others of the ablest of the younger school of 

 German physicists. He came to London in 1850, and there made the 

 acquaintance of Faraday. Of his first meeting with the man of whom 

 he has often spoken as "my master "he has given us a charming account 

 in his life of Faraday. Immediately on his return to England he 

 received an appointment at the Royal School of Mines, where he 

 found among his colleagues his life-long friend. Professor Huxley. 

 In 1852 he was appointed Professor of Physics at this school, then
