	Yesterday, somebody brought me a fuse (looking for a replacement)
from a piece of laboratory equipment which has me puzzled.  It looks on the
outside like an ordinary fuse (the small glass cylinder type, about an inch
long, with metal ends), but inside had a small (1/8 W?) 22-ohm resistor in
series with the fuse wire.  It was an 1/8A fuse.  Didn't say slow-blow on
it, so I assume it wasn't.

	Anybody have any idea why it contains an internal resistor?  Why
not simply have the same resistor mounted externally in series with the
fuse holder?
