If you will have a number of brushes prepared in this way (larger radius) we should first like to have these, in order to perform the experiment on the amount of bedding that is required for different radii, as it may not be easy in the first instance to obtain the most suitable radius. We would also be prepared to make experiments on the polished brushes, when they return from Mr. Lawrence of the Le Carbone Company - if experiment is considered necessary in this instance. EFC. {E.
