The elderly gentleman - his hair was quite white now - slowly shook his head, as he murmured again: "It can't be done, Tom It can't be done I admit that you've made a lot of wonderful things - things I never dreamed of - but this is too much. To transmit pictures over a telephone wire, so that persons cannot only see to whom they are talking, as well as hear them - well, to be frank with you, Tom, I should be sorry to see you waste your time trying to invent such a thing."
