x WILD AND CULTIVATED COTTONS 



drawings have been reproduced in colour and half life size : namely, 

 Plates nn. 30 and 48. I take this opportunity to acknowledge the 

 untiring efforts of Miss Smith to secure accuracy in detail combined 

 with artistic delineation. In this connection also I may explain that 

 the photographs of types given have been made from dried botanical 

 specimens, collected many years (or even centuries) ago, some of 

 which are, unfortunately, not in the best state of preservation, and 

 moreover were dried and mounted long before it was realised what 

 should constitute a botanical specimen. In some cases the types 

 are glued on to sheets of paper or pages of books, in others held 

 in position by narrow bands of silk gummed across them (see Plates 

 36, 37, 38, and 39). It is, however, believed that the reproduction of 

 the authentic types of the species of Gossypium may prove of value 

 to botanists, planters, and seed-producers throughout the world.
