| Contd. -2- EFC3/T23.5.23. It is thought that an intermediate instrument giving 0 to 5000v and 0 to 15,000 volts would be most generally suitable. Before proceeding further we should be glad to have your confirmation in the case of the oscillograph expenditure, and your views as to the value of results which might be obtained with the other apparatus.
