Description | 'Dear Sirs, Prof. Worthington is not content with the specimen reproduction which you sent us. The "coarseness of the Graining" he thinks fatal for the particular purpose of the prints, and the pictures to be of us will have to stand examination with a lens. Will you, therefore, let us have an alternative estimate for reproduction by collotype? and if you will send here for six negatives which Prof. Worthington has selected, you might do one as a specimen. Yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. |
