Crass II. TARROCK GULL. 
orange; the legs dusky, with only a knob in- 
stead of the back toe. 
It inhabits the romantic cliffs of Mambo- 
rough-head (where it is called Petrel) the 
Bass Isle, the vast rocks near the Castle of 
Stains, in the county of Aberdeen, and Priest= 
holm Isle. 
The young of these birds are a favourite dish 
in North Britain, being served up roasted, a 
little before dinner, in order to provoke the ap- 
petite; but, from their rank taste and smell, 
seem much more likely to produce a contrary 
effect.
