I'm glad this book exists: "The Diamond Lens" is a magnificent short story and deserved to have been reprinted more (the others here I can take or leave), with an obsessed scientist and a strange new life-form. But this Obverse Books edition could have been done much better; there are many errors of typesetting, including that the type fluctuates in size between stories, and chapter headings are done inelegantly at best. The cover is attractive, but with these interiors, you should probably just stick to Project Gutenberg.
