 in individtial [ictals, ov to actiial tiansition cases, which could bo only thus 

 classified. In all these cases the actual continuity of the character observed was 

 easy to dcmonstrate, and there was no hesitation in applying the inethods of 

 continuoiis Variation. The deterniination of the dividing lines for purposes of 

 calculation was niade in general for 2 or 8 ditf'erent gnjupings and the niean 

 resnlt appears in Table XI.

First Floiver on Oxford Poppies. Fraternal Correlatiov. 



If we add to these the Oxford result of the previous table for the stigmatic 

 bands of all capsules, i.e. •2891, we have for the average relationship of pairs 

 of brothers in the Oxford crop -2514, — a result in excellent accordance with what 

 we might expect from the case of man (-.5), if we allow for most complete cross- 

 fertilisatioii in the original Hampden crop*. 



Lastly W. F. R. Weldon made two otlier measurements on some 600 Oxford 

 plants, (i) the height above ground of the node from which the terminal flower 

 was giveu off, (ii) the height of the terminal seed-capsule from the ground. 

 A. Lee has found the fraternal correlation for these two characters, which are the 

 only plant as distinguished from pure tlowei- characters dealt wdth.

* 1899 was a remarkably fine dry summer and the bees were at werk on the Hampden poppy crop
