Egg. — From 7 to 10 in number; four nests found by myself at Myvatn, June 1891, 
contained 7, 7, 8, 8 eggs ; texture of shell, smooth ; shape, oval ; colour, rich cream ; size, 
from 2-^^ by ii§ to to iff inch" (Dresser). Jourdain gives 5 to 10 as the number, and 
usually 6 to 8, with the shape elliptical or short oval, and the shell hard and only fairly 
glossy and smooth. The same authority informs me that the eggs vary from creamy-yellow 
to pale yellowish-brown or pale cinnamon-buff. Average size of 60 eggs 57.61 x 41.74 mm. ; 
maxima, 61x42.5 and 59.44; minima, 52x39 and 54x38.7 mm. (F. C. R. Jourdain). 
Average weight, 3.523 gr. (3.21 to 4.08 gr.) (Rey) ; 3.40 gr. (Gobel). 
Down. — Larger than that of most ducks, with individual sprays with a diameter of 
If inch (Pearson, Ibis, 1895, p. 244); colour, greyish-brown, with light greyish-white 
centres. The down is lighter than either Scaup or Scoter (Jourdain). 
Young in Down. — Crown, lores, nape, thighs, and whole of the upper parts, dark 
brown with a greyish tinge. Cheeks, chin, throat, and under parts, white ; a white spot 
over and somewhat in front of the eye, and on each side of the back and over the thighs ;
