  <dc:title>Copy letter from Robert William Frederick Harrison, to Sidney R J Smith, 14 York Buildings, Adelphi </dc:title>
  <dc:description>'Dear Sir, 
With further reference to your letter of the 8th instant. I am informed that the phenomenon you refer to is a very well known one, it is an instance of the so-called 'contrast' effect.
I am, 
faithfully yours,
Robt Harrison
Assistant Secretary, R.S. [Royal Society]'.</dc:description>
