So do I as I already confessed. :-))

As for that, I have been out of fluid mechanics for half a century but  
back then, at least as I recall, we used an overline for coordinate- 
free notation of vectors and a double overline for second order  
tensors etc but I can't remember how we distinguished contravariance  
from covariance. In any case, the overline circle n was, I think, my  
generalization so as to deal in a uniform way with mass, momentum and  
energy as well as with both the Lagrange and Euler descriptions.

And here, Ladies and Gentlemen, is the only extant LaTexed page of the  
historical document---which I had certainly not meant to inflict on  
this list. That it was mentioned on this list was the result of a  
comedy of errors.
