Even these figures jirobably give an exaggerated idea of 

 the amount of crossing which takes place between one field 

 of jute and another. The excessive number of red plants in 

 plot 55 is probably due to accidental contamination of the seed 

 before sowing. 



Conclusions. 



From the data in this paper we conclude that : — 



(1). When a pure green jute, i.e., one containing no red 

 colour, is crossed with a fixed red plant, or vice versa, Mendel's 

 law is obeyed, the red acting as a simple dominant. 



(2). The Fi generation of hybrids appears to consist entirelj' 

 of plants of one tint of redness, which, it should be noted, is 

 less dense than the colour of the red parent. The red plants 

 of the Fj generation, on the other hand, vary widely in the 

 amount of red colour thej^ contain. Moreover, seed from red 

 plants of the Fj generation has produced progeny of the F3 

 generation which, though apparently quite fixed as regards 

 possession of red colour, shews, in most cases, the same varia- 

 tion between individuals in regard to the intensity of red colour- 

 ing, as characterized the red plants of the Fj generation. 



(3). The facts [a), that one result of these experiments 

 has been to produce examples, fixed or unfixed, of all the inter- 

 mediate colour types of jute hitherto met with, including a 

 pure fixed culture of one of the commonest of these ; {h) that
