Item 135 - James David Forbes to William Whewell

4 pp

Pitlochry, N.B. - JDF will shortly submit to WW his reply to John Tyndall [Reply to Professor Tyndall's Remarks in his Work 'On the Glaciers of the Alps' re. Rendu's 'Theorie des Glaciers', 1860]: 'If you find anything redundant, or unsatisfactory or out of temper, you will do me a favour by marking freely'. Did WW receive his letter in Paris, in which 'I ventured to suggest your writing an article on the glacier theory in the Quarterly, where the question is still open' [see JDF to WW, 31 July 1860]. He has received surprise support from John Moore Heath, 'with whom a year ago I had a rather unsatisfactory correspondence on the subject. He was then apparently on Tyndall's side. He now writes that Tyndall's own Book has fully convinced him that I am entirely in the right and he gives in his letter a masterly refutation of some of his alleged demonstrations against viscosity'.
