This extraordinary little book's dramatic title is expanded in a lengthy subtitle, reading "A Report on the Strange Findings in Undergarments Washed with Soap and Water, and Popularly Supposed to be Clean, Fresh and Wholesome". Appearing in the inter-war period, it offers an insight into the early 20th century's slow realisation that the world is full of unseen dangers, many of them present in the day-to-day life of any normal household - a concept that has of course resulted in our 21st century obsession with cleanliness and 'germ-free' environments (and the related profusion of allergies and other conditions associated with poor immune systems).
We have no information about the author, who was evidently a scientist working in Leicester on behalf of Leicester Royal Infirmary, who were perhaps particularly concerned about cleanliness within their wards.
The book is unassuming in appearance, bound in dull, darkened buff-coloured boards, with a brownish cloth strip protecting the spine. The title etc are in black print on the front. Inside, the binding is firm and the pages clean. There are more than 130 illustrations (micrographs) to enforce the general message that what you see is not necessarily what you get.... A fascinating little book, interesting as a piece of scientific history.
