Mark R. Sullivan, San Francisco, president and director of the Pacific Telephone & Telegraph Co., said in an address Thusday night:

"Just what form the future telephone will take is, of course, pure speculation. Here is my prophecy:

"In its final development, the telephone will be carried about by the individual, perhaps as we carry a watch today. It probably will require no dial or equivalent, and I think the users will be able to see each other, if they want, as they talk.

'Who knows but what it may actually translate from one language to another?"
