Item 173 - Letter from John Tyndall to Henry Sidgwick

Writes in reply to Sidgwick's plea for a recommendation of a teacher. Observes that Sidgwick's difficulty is enhanced by the range of subjects which he requires the teacher to undertake. Suggests that he limit himself for the present 'to such subjects as can be taught in a real and healthy manner'. Claims that the back-bone of modern science is formed by chemistry and physics. Announces that he knows of one man who is likely to suit Sidgwick's requirements: a German, Dr Debus, who is a chemist, has a thorough knowledge of physics and is a good mathematician. He is a Fellow of the Royal Society and an examiner of the University of London. He has been teaching boys in England for the previous fifteen years. Explains that he recommended him some time ago to a professorship at Sandhurst 'but they preferred an Englishman.'
