| Title | Copy letter from Robert William Frederick Harrison, to Willliam H Carder, Secretary of the Staffordshire Iron and Steel Institute, Burnt Tree, Tipton |
| Date | 5 October 1906 |
| Description | With further reference to Carder's letters of 28 September and 2 October, on examining the illustrations to Mr Rosenhain's paper in the 'Philosophical Transactions [of the Royal Society]' Harrison finds the plates were reproduced by the photo-collotype process and that it is therefore not possible to obtain electros for Carder to use. It is open to Carder to copy the illustrations and Rosenhain might be able to lend the negatives for this purpose. |
