An Introduction to the Geometry of N DimensionsFor many years, this was the only English language book devoted to the subject of higher dimensional geometry. While that is no longer the case, it remains a significant contribution to the literature, exploring topics of perennial interest to geometers. In the first four chapters, author D. M. Y. Sommerville explains the fundamental ideas of incidence, parallelism, perpendicularity, and angles between linear spaces. Chapter V presents analytical

For many years, this was the only English-language book devoted to the subject of higher-dimensional geometry. While that is no longer the case, it remains a significant contribution to the literature, exploring topics of perennial interest to geometers.
In the first four chapters, author D. M. Y. Sommerville explains the fundamental ideas of incidence, parallelism, perpendicularity, and angles between linear spaces. Chapter V presents analytical geometry from the projective point of view, exploring some of the simplest ideas relating to algebraic varieties and offering a more detailed account of quadratics. Chapter VI examines analytic geometry of n dimensions from the metric point of view. The remaining four chapters deal with polytopes and address some of the elementary ideas in analysis situs. Chapter VIII treats the content of hyper-special figures, and the final chapter establishes the regular polytope.

Format: Paperback
Lame art and bad prose. This amateur effort deceived my by one good review. Writing this review to tell you not to waste your money.

Better then the competitors
Size: Medium Size
I bought these in both small and medium size. The small bag fits the Kitsch solid hair soap perfectly. They also fit a bar of Dove soap. Some types of soap, like Zest, are a tighter fit bit still work. If you want more of a washcloth style with extra suds, use the medium bag. The medium bag works well with those large bars of soap, like Duke Cannon Big Brick of soap. I hand these off little hooks in my shower so the bag dry faster and so I appreciate the loop they have on the corner. The folding top works way better then a drawstring. I also love the exfoliating texture. Overall, these are well worth the price.

Good exfoliating soap bag
Size: Small Size
Pretty good soap bag. Does take a while to get it to foam soap, maybe I'm doing it wrong? Great scrubbing.

Perfect for travel!
Size: Small Size
Love these and perfect for my bar soap. European hotels love their body wash refillable bottles but I like my soap! This keeps my bar soap clean and prevents me from dropping on the hotel shower floor. Also makes it nice for packing as it takes up less room than a soap dish. Last a long time! Use this all the time on monthly trips and is just like new. Good buy!
