What is MACHE again?

I'm going back through my notes and I remember TACE... it's TASSE or TASSET which is thigh armor.  And DACE is a kind of fish.

But what is MACHE again?  I'll have to look it up...

Wait for it..

Oh, yes, MACHE is a European herb.

Although I think I will find it easier if I try to remember that it is also unit of measurement:

MACHE (symbol ME from German Mache-Einheit, plural MACHES) is an obsolete unit of volumic radioactivity named for the Austrian physicist Heinrich Mache.It was defined as the quantity of radon (ignoring its daughters; in practice, mostly radon-222) per litre of air which ionises a sustained current of 0.001 esu (0.001 StatAmpere).
