In a paper appearing in a recent issue of this journal(!) GoLD- 
SCHMIDT reviews the main results which I have obtained in the course 
of a prolonged series of breeding experiments on the inheritance of 
the double character in Stocks (Matthiola), and incidentally also, 
certain results regarding the inheritance of plastid colour in the same 
plants. The chief data which form the subject of discussion are set 
forth in my paper in the Journal of Genetics (tg11) and in the Report 
of the fourth International Conference on Genetics (Paris, 1911), while 
certain earlier observations appear in Reports I—4 to the Evolution 
Committee of the Royal Society (?). 
After reviewing the data contained in the above papers, and the 
scheme which I there suggest underlies these data, by means of which 
they can be brought into line and interpreted, GOLDSCHMIDT gives it 
as his opinion that the facts point rather to the conclusion that we 
have here merely another case of ordinary sex-limited inheritance. 
Having, as he says, been led to conclude that the inheritance of the 
sex character in hermaphrodite flowering plants can be explained in
