Copy letter from Robert William Frederick Harrison to Dr E F Bashford 'Will you kindly look at the enclosed figures. The one marked Russell is evidently a pull of a block. Can we have this block, or the use of it, for the paper in Proceedings. The two marked Woglom - Fig 1 is a print from a block. Can we have the use of this block also. Fig 2, a bromide print, perhaps you have the block of this by now, as your letter of the 14th said you were preparing blocks. These half-tone blocks of yours seem to have a very fine screen, much too fine for printing on our text paper. We shall therefore probably have to make a plate of them.' 26 March 1912
