Copy letter from Herbert Rix, to the Editor, "Pharmaceutical Journal", 17 Bloomsbury Square, W.C. 'Dear Sir, I am afraid that you do not understand that the card sent out on Monday, which would reach you by Tuesday morning, is the announcement of papers to be read the same week, namely, the very day you go to press, I fear, therefore, the card would be of no use to you; still, if you care to have it, of course you can. I am, yours truly, H Rix Asst. Sec. R.S. Assistant Secretary, Royal Society]'. 28 April 1894
