 drew my attention to the matter, and has given me many helpful hints with 

 regard to these birds. 



I must further add that the studies of heads reproduced with this were all 

 made from life, but not aU from the same individuals, the set being completed as 

 time and opportunity offered, but are none the less, I believe, typical of the 

 development of the average Moorhen chick.
