of microbes was welcome and admirably explored. He noted few errors, but objected to Postgate's assertion that AIDS "originated by transmission from a primate", for which there was at that time no evidence. Schneider would have liked a "better and longer" account of molecular biology. His chief criticism, however, was that by the 1990s the book no longer had an audience, since "the Victorial ideal of the educated middle class has vanished into the wasteland of broken families, double digit unemployment and a damaged educational system". All the same, he found the book "of value and beauty (except perhaps to the publisher)". Charles W. Kim, reviewing the 3rd edition for The Quarterly Review of Biology, stated that "If the author's intent was to present the impact of the ubiquitous microorganisms on the environment and humans, he has succeeded admirably", describing Postgate's style as "unique". D. Roy Cullimore, in his Practical Atlas for Bacterial Identification, comments that all four editions were "easy reading", addressing the challenges that microbes presented to human society. He suggests that "ideally" all four books be read in sequence for an overview of the development of microbiology in half a century.
