Editor's Notes
Notes on Short's telephone. Drawings & calcs on geometry of button, diaphragm, followed by vague sketches. Exploring Short's claim that positioning of diaphgram supporting arms increase diaphragm's range of motion. (Interference test being taken about now.) FR 998 BEGINS APRIL 2 ENTRY Short's analogy between motion of diaphragm and of fixed beam is in now wise correct. More expts with Short trans. Fr 1003 begins ELight stuff, with lots of calcs, at least some concerned with photometric expts.
