4pp., 12mo. Bifolium. Very good, on lightly-aged paper. He begins by commending the recipient's 'interesting paper': 'Of the justice of your remarks there can of course be no doubt, and even the small amount of knowledge that I have been able to acquire of the nature of rocks, has for some time past convinced me of the importance of what you '. He explains that he did his best 'in getting specimens of the Lafoten rocks, but the tast was very difficult and very unsuccessful, owing to the great hardness of the rocks. Quarries of course were absent'. When he 'wrote a short paper which I sent to the Geological Society I had not got book - I have since looked at the part about the Lafotens but it appears to me that he is by no means clear about the nature of the rocks there, although it is evident that he regarded many parts as metamorphic. Forbes calls mempanite and Mr Dahl in conversatino with myself maintained that they were, so knowing that he was a geologist of some repute and finding it almost impossible to get hold of Norwegian books I concluded that the opinion expressed by Travellers was generally held'. He concludes by stating that 'Since asking the question about Dolomite' he has 'come upon Mr Sorby's paper. [Henry Clifton Sorby (1826-1908)] He is doubtless right - Mr Hunts speculations seem to me very wild.'
