Copy letter from Herbert Rix, to W G Spencer, 35 Brook Street, W. 'Dear Sir, We have had a specimen done for your tracings, and I am now in a position to give the order if you are satisfied with the result. Messrs Edkins & Co. inform me that they have already submitted the specimen to you, but I should be glad to have from yourself confirmation that you are satisfied with the result, as the order will, of course, he rather a large one. Please return copy and proof. I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 27 April 1894
