You mean at Denmark Hill?--Yes; that deterioration on pictures of the class I refer to is not to be afterwards remedied--the thing suffers forever--you cannot get into the interstices. _Professor Faraday._ You consider that the picture is permanently injured by the dirt?--Yes. That no cleaning can restore it to what it was?--Nothing can restore it to what it was, I think, because the operation of cleaning must scrape away some of the grains of paint. Therefore, if you have two pictures, one in a dirtier place, and one in a cleaner place, no attention will put the one in the dirtier place on a level with that in the cleaner place?--I think nevermore. 119. _Chairman._ I see that in your "Notes on the Turner Collection," you recommended that the large upright pictures would have great advantage in having a room to themselves. Do you mean each of the large pictures or a whole collection of large pictures?--Supposing very beautiful pictures of a large size (it would depend entirely on the value and size of the picture), supposing we ever acquired such large pictures as Titian's Assumption, or Raphael's Transfiguration, those pictures ought to have a room to themselves, and to have a gallery round them. Do you mean that each of them should have a room?--Yes. _Dean of St. Paul's._ Have you been recently at Dresden?--No, I have never been at Dresden. Then you do not know the position of the Great Holbein and of the Madonna de S. Sisto there, which have separate rooms?--No. _Mr. Cockerell._ Are you acquainted with the Munich Gallery--No. Do you know the plans of it?--No. Then you have not seen, perhaps, the most recent arrangements adopted by that learned people, the Germans, with regard to the exhibition of pictures?--I have not been into Germany for twenty years.
