No sensitivity given for coherers (perhaps too  many types?)
Magnetic detector:
	'more sensitive than coherer'
		estimated 0.0025 erg for a dot
(' R A Fessenden proposed to construct a 'recording detector'
hmmmmm.  Wire Recorder?)
Electrolytic Detector:
		estimated 0.001 erg for a dot
etc...

	magnetic detector ... more sensitive than coherer,
	less sensitive than electrolytic or some contact
	detectors (crystal).
