National Nature Reserves. All this is illustrated with good colour photographs and paintings. I particularly admire those by Helmut Diller. The last section of the book is devoted to an illustrated list, with notes, of all the extinct and endangered birds and mammals of the world as known to ICUN at the end of 1969. I am sure every serious-minded person will find this book of absorbing interest, and it is comforting to know that royalties from its sale will go to the World Wildlife Fund.
