ThePETREi.s [Procellaria, Linn.) arc characterised by a gibbous 

 beak, the extremitjr of which is hooked, and seems made all in 

 one piece, and as if jointed on to the rest of the upper mandible. 

 These birds never dive, and rarely swim ; but in their rapid flight 

 they skim over the waves, and actually appear to walk upon the 

 waters. To this habit they owe the name of Petrel, which simply

 to the water. They never draw near to the coast except to build 

 their nests, for which purpose thej^ select a little crevice in some

 spinning-wheel.

 down and the oil which can be extracted if-om their stomachs. 

 The quantity of oil which these birds contain is so large that it is 

 used as an article of diet. In the Feroe Islands candles are 

 made from this oleaginous matter. Often, indeed, the islanders
