[…] According to this book, the public image of Poe as this ghoulish creepazoid is inaccurate. His work was creepy, but he wasn't."

Ferguson's sin consisted in his oracular 'unmasking' of a 'second-rate sort of society, full of second rate citizens, pursuing comparatively worthless objects.'

Four-to-a-room is living in close quarters.

If f(x)∈ Z [x], the ring of polynomials with coefficients in Z , then the content of f, denoted by c(f), is the greatest common divisor of the coefficients of f. The polynomial f(x) is called a primitive polynomial if c(f)=1. Since c(fg)=c(f)c(g), by Gauss's lemma [Hungerford, 74], the set S of primitive polynomials in Z [x] is a multiplicatively closed set. Define 𝛬= Z [x]_S, the localization of Z [x] at S, a subring of the field of quotients Q (x) of Z [x]. Elements of 𝛬 are of the form f(x)/g(x) with f(x),g(x)∈ Z [x] and g(x) a primitive polynomial.
