No, of course not! Something must be wrong. I didn't
mean that. Wait, I'll take a look. Say, it does seem as if

and soon Tom saw the clearest image he had yet observed on his
telephone photo plate.
"Switch me on now, Ned," he called to his chum, and Ned reported
that he could see Tom very plainly.
"So far--so good," observed Tom, as he came from the booth. "But

a friend, and then switch on the picture plate, so he can see his
friend as well as talk to him. I want this plate to be like a
mirror, so that any number of images can be made to appear on it.
In that way it can be used over and over again. In fact it will be
