Fig. 61 is an illustration of Brazilian seed cotton. These seeds have 

 a brownish-black colour ; they are oblong in form, finely fluted, and the 

 seeds cohere together in the masses of cotton in the form of a kidney, 

 as shown in the six examples. This character has given rise to the terra 

 Kidney Cotton, which is peculiar to the Brazils.

Fig. 62 shows the Brown Egyptian or black-seeded cotton. The fibres 

 are long in staple, but slenderly attached to the seeds. They are mostly 

 cleaned by the "Roller" or the "Macarthy " cotton gins. 



The Egyptian, Sea Islands, and the Australian cottons are sometimes 

 called " the black-seeded cottons." They are all of long staples, and are 

 the product of G. Barbadense. 



East Indian or Surat cotton seeds have a dense downy covering and 

 shorter than the seeds of other species. As a rule, the fibres of East 

 Indian cottons are short in staple, but strongly attached to the membrane 

 of the seeds, and are therefore much harder to gin, particularly in the 

 variety known as Scinde cotton.
