THE author has very ably dealt in 268 pages with nearly all the important plant products of the world. Short explanatory notes to each of the products mentioned are authentic, accurate and up to date. Eleven pages of bibliography at the end of the book is a valuable addition. Those interested in further information on any one of the products discussed in the book can consult the particular literature relating to that product. Common vernacular names used generally in different countries might have been added for the advantage of local dealers in plant products. Short notes on the marketing of those products would also have been encouraging to the producers. With the progress of research on various plant products, and the discovery of the uses of many hitherto unknown plants in different countries, particularly in India, Burma and Africa, the list of plant products is growing so rapidly that it is to be hoped a second edition will be quickly necessary ; slight discrepancies in some places might then be rectified also.
