I determined the composition of the cultures of the 

 next year, 1899, in the same way; they were both raised 

 from the seeds of h'lac plants. One of them (5th gen- 

 eration) flowered partly in 1899 and partly in 1900; 

 but the other only in 1899. The result was as follows:

The first list is based on 1 55 flowering plants, and the 

 second on 219. 



The seeds of the whitish Hcspcris, therefore, in this 

 experiment, produce their like with a small percentage 

 of lilacs and violets. The seeds of lilacs, on the other 

 hand, give rise to the three types in about equal numbers, 

 though it must be remembered that the limit between 

 //':] and L\ is to a certain extent arbitrary. 



I have not yet made a sufficient number of observa- 

 tions on the inheritance of the violet color in this race. 

 In the only experiment which I have carried out, only 

 five plants flowered and they had the same color as their 

 parents. 



Let us now pass on to a detailed description of the
