I remember many years back in HemePath using B3, B4, and B5 and they were
different formulations, and I think the number had to do with the
concentration of mecuric chloride, as I recall, B3 had less mercuric
chloride than B5.

		"B" was for buffered sublimate, meaning a buffered mercuric
fixative.

		"5" because it was the 5th formulation that was the best. As
opposed
		to B-12 or B-17.

		(Wouldn't that have been fun - having a fixative that people
think
		was named after a vitamin or an bomber! That would have
added
		to the confusion!)
