Sometime ago Mr. Brock informed me when discussing the question of variations in capacity of paper condensers, that he had been able, by building up a condenser with varnish interposed between the layers of paper and pressing it, to eliminate the variation in capacity which seemed to be characteristic of the paper condenser. As to whether it eliminated variations in temperature as well as variations due to periods of time, I do not remember, but if either of the variables could be eliminated it would certainly be a distinct gain. Whilst bringing the matter before you I fully appreciate the fact that any change in condenser manufacture requires very careful and extended testing to prove the change either satisfactory or faulty. I would like to have your views in regard to the proposal in question, as if it appears likely to be successful it would be desirable to make up a number of condensers and run same on the experimental cars in order to test out the question of reliability.
