SKETCH OF PROFESSOR TYNDALL. 105 



not being satisfactory, he rejoined, " You have five hours a day at 

 your disposal, and this time ought to be devoted to systematic study. 

 Had I, when at your age, had a friend to advise me, as I now advise 

 you, instead of being in a subordinate position, I might have been at 

 the head of the Survey." Next morning Tyndall was at his books be- 

 fore five o'clock, and for twelve years never swerved from the pratice. 



In 1844, seeing no definite prospect before him, Mr. Tyndall re- 

 solved to go to America, whither, in the early part of the present cen- 

 tury, some members of his father's family had emigrated, and who now 

 reside in Philadelphia. 1 This was, however, opposed by his friends, and, 

 an opening occurring, he entered upon the vocation of a railroad en- 

 gineer. To five years upon the Ordnance Survey succeeded three 

 years of railway experience. But, this proving unpromising, and ani- 

 mated by a strong desire to augment his knowledge, Mr. Tyndall re- 

 signed his position, and accepted an appointment in Queenswood Col- 

 lege, Hampshire a new institution devoted partly to a junior school 

 and partly to the preliminary technical education of agriculturists and 

 engineers. Prof. Tyndall here developed a remarkable capacity as a 

 teacher. Although totally inexperienced in this field, such was his 

 magnetic influence over the students, that he was invariably called 

 upon to compose their disturbances, which he did by moral influences 

 and pure force of character. It was his experience in this institution 

 that gave him the groundwork of his masterly address on education 

 before the Royal Institution. 2 



In 1848, in company with his friend Frankland (now Prof. Frank- 

 land, of the Royal School of Chemistry), Tyndall quitted England, 

 and, attracted by the fame of Prof. Bunsen, repaired to the University 

 of Marburg, in Hesse-Cassel. Prof. Tyndall had the free use of the 

 laboratory and cabinets of this institution, with the instructions of 

 Bunsen, Gerling, Knoblauch, and Stegman. His first scientific paper 

 was a mathematical essay on screw-surfaces, which formed the subject 

 of his inaugural dissertation when he took his degree. But the investi- 

 gation which first made him known to the scientific world was " On the 

 Magne-optic Properties of Crystals, and the Relation of Magnetism 

 and Diamagnetism to Molecular Arrangement." This investigation 

 was executed in connection with Prof. Knoblauch, and was published 

 in the Philosophical Magazine for 1850. 



In 1851 Mr. Tyndall went to Berlin, and continued his researches 

 in the laboratory of Prof. Magnus. He soon, however, returned to 

 London, and was elected Fellow of the Royal Society in 1852. He 

 was invited to give a Friday evening discourse at the Royal Institu- 

 tion, which he delivered February 14, 1853, and was so successful that 



1 One of these is Hector Tyndale, who distinguished himself as an officer in the late 

 war. At Antietam he fought as major, and for his gallant behavior was subsequently 

 made brigadier-general.
