a column of mercury, from across the lab. In this case, the "thing"
you are looking at has a scale attached... Joel in Florida
I thought that 1614 was a surveyor's level but now I'm thinking you might be
right about it being a cathetometer, I'll send an email to the owner and see
what he has to say.
