```Hi Justin,

Thanks for coming back. I discovered by the way today that in addition to
Sraffa being out of print in London, Steedman's Marx after Sraffa is out of
print.

Although I suspect magic is hidden in this table, I am seeking an
elementary explanation of what are the rows and columns and how they
relate to each other.

An explanation line by line as if I was an intelligent child would be
helpful to establish if there is something robust in Sraffa's model and
I am being over sceptical, or whether the obscurity of the mathematics
is impressive, but it is just a variant of the theories of economics
that are limited to circular descriptions of prices of production.

Thanks,

Chris B
