I want to know how the devil they can tell if the blood comes from a bull,
steer, or cow--OR if they even know the difference?

BTW:  Camille, I love your middle name, where is it from?  Ruth



"We can look at a masons work to see if its good how in the hell can I look
at a lab 's work and see if its good "



Py, I'll give a quick answer.  I think judging a mason and a lab are really
not that different.



1)       Instead of just asking for a mortar analysis decide what kind of
questions you have.  Ask all of those things you mentioned (e.g.; can you
identify hot-mixed tabby and bull's blood?).  If two labs answer your
questions differently than challenge them on each other's answers.
