NOTES ON INHERITANCE OF COLOUR AND 

 OTHER CHARACTERS IN PIGEONS.

 Fellow of King's College, Cambridge. 



For some years I have carried on experiments on the heredity of 

 certain characters in pigeons, and since circumstances prevent me from 

 continuing the work further, I publish the results so far as they have 

 gone, although they are in many respects incomplete. The space at 

 my disposal was not sufficient to do the work on a large scale, so that 

 although it has been in progress for almost six years, the results are not 

 very extensive. In beginning the work, three separate series of ex- 

 periments were planned of which the first was concerned with the 

 inheritance of leg-feathering. 



Series A. Leg-feathering. 



Since the colours were very complicated and difficult to describe, in 

 this series no attempt will be made to deal with them. The first
