BOLLS OF PERJUGATE HYBRIDS 



They represent the second generation from a cross of Egyptian and Hindi cottons. The six 

 specimens represent six consecutive sister plants raised from seeds from the same boll 

 of the conjugate parent, produced from a self -fertilized flower. Compare the diversity 

 of these bolls with the relative uniformity shown by the conjugate generation in the preced- 

 ing illustration. Photograph natural size. (Fig. 2.)
