however, tolerably rapid, being sustained by quickly repeated 

 strokes of the pinions. They breed upon the ledges and pre- 

 cipitous summits of rocks overhanging the sea, laying one 

 large conical egg, broad at one end, and very narrow at the 

 other, it being prevented by this form from rolling off the 

 shelving place of its deposit. From the backward position 

 and confined movement of the legs, their progress on land is 

 very limited ; and they sit, in an upright position, upon the 

 foot and whole length of the tarsus. Their plumage is very 

 thick, close-set, and, in the living state, impervious to the ac- 

 tion of the water. They are subject to a double moult, and 

 their summer (or nuptial) dress differs in many respects from 

 that of the winter.
