of the restorer. While not prepared to give a final 

 opinion as to the safest methods of cleaning, Prof. 

 Laurie suggested that where alcohol is used castor-oil 

 should be laid on the surface with a soft brush, and 

 then a mixture of castor-oil and alcohol dabbed on 

 with a soft brush, and removed by diluting with 

 turpentine and sopping up with a large dry brush. 

 Where alcohol is not a sufficiently powerful solvent 

 copaiba balsam emulsified with ammonia might be 

 used, a preparation of copaiba balsam thinned with a 

 little turpentine being laid on the surface first. If any 

 friction is to be applied it should be done with a soft 

 rubber point, and at every stage examined under a 

 powerful magnifying glass. No important public pic- 

 ture should be cleaned until it has been authorised 

 by a committee of experts, and the cleaner himself 

 should be present and explain exactly what he is 

 going to do, while everything he does should be under 

 the direct supervision of the head of the Public Gallery.
