He also called the attention of the meeting to the ravages of 
insects (apparently Anobia ) upon the pictures in the National 
Gallery, and read an extract from the parliamentary Report upon 
this subject;* and suggested that it might be serviceable to satu- 
* The parliamentary Report relative to the state of the pictures in the National 
Gallery contains the following evidence : 
Mr. Seagur states that the Sebastian del Piornbo has been occasionally eaten 
round the edge by a little worm, which is confined to a particular spot merely at 
the edge. He thinks the worms of very little importance. 
Mr. Jno. Peel states that the Sebastian del Piornbo is in the worst state of any 
in the collection, that it is going to decay, as fast as it possibly can. owing to 
the worms which have got into it, both the meal worm and the woud worm. He 
thinks the worms are now eating very fast, and in fact they are destroying the pic- 
ture piecemeal. They are encroaching 6 to 18 inches from the edges towards the 
centre. 
When asked whether relining would remove the insects, &c. ? Yes, it would 
completely. 
Mr. E. Solly confirms Mr. Peel’s statements with respect to the worms to be 
found in the Sebastian del Piornbo, and states that he had in his possession last 
year two of the small beetle kind: they were given to him by a foreign professor, 
who took them off the picture himself.
