Of this F, generation the following ones are available for comparison, 
either in stuffed condition, as feather-charts, or still alive. In the follo- 
wing genealogy those still alive are printed fat:

The F, cocks 
We can thus compare the F, cocks: 
206.1 — 206.3 — 282.1 — 282.2 — 276.1 — 276.2 — 276.3 — 276.7 
and 276.11 &, nine in all. 
The two cocks 206.1 and 206.3 differ greatly in size. 
206.1 4 was a heavy animal (see colored plate Il fig. 2) of large size 
quite comparable to that of an ordinary barnyard cock, while 206.3, as 
all the other animals obtained from these crosses, had the size of an or- 
dinary bantam. 
To this exceptionally large size considerable importance was atta- 
ched, as long as we imagined the animals originally purchased by Mr. 
HouwiInk to be pure bankiva’s, but as we know now that they contai- 
ned some other blood the importance of the case diminishes greatly, 
although it remains interesting that so large an animal could be rai- 
sed from small stock, after crossing with Sonnerat, while the inbred 
bankantams never threw a large animal. 
Of this large F, cock 206.1 we find the following notes, taken by the 
junior author, at the time when the animal was drawn.
