B.T.W. What Flower is that?, by E. M. Barrand. 10s. 6d. Worcester, Littlebury and Co. Ltd. Identification of flowers is in three sections, the first being subdivided into (a) flowers everyone knows, (b) common, (c) easy, (d) difficult flowers. The second section deals with identification by colour, and the third is a list of flowers in alphabetical order, with a description of the parts of the plant and its scientific name. To find out more about the plant families, readers are told to consult more advanced text-books. As a book for town visitors to the country or for children, it is useful, especially by reason of its arrangement in sections. It should quickly whet the appetite of readers to consult the text-books. The black and white drawings are clear and give a good impression of the appearance of the flowers E.M.J. It is our sad duty to report the death of Percy Cr. Thompson, F.L.S., who played a leading part in the affairs of the Club for so many years. He passed away very peacefully on April 7th, 1953, aged 86, at the home of his daughter, Mrs. Doris Newbury. The funeral service was held at Bt. John's Church, Loughton, on April 11th, when the Club was represented by four members. As this number of The Essex Naturalist is already in the hands of the printers, an appreciation of Mr. Thompson's life and work must await the publication of the next issue.
