I. Tivo Specimens of Egyptian Geese (Anser Egyptiacus) were exhibited

The birds, a male and a female, were shot in the neigh- 

 bourhood of Dunbar, in the beginning of this month, and 

 were sent by Mr Small, bird-stuffer, George Street. They 

 are natives of the north of Africa, and of the south-eastern 

 parts of Europe, and have been kept in a semi-domesticated 

 state in various parts of England and Scotland. Several 

 instances of single specimens of the bird, as well as small 

 and even large flocks, apparently in a perfectly wild state, 

 have, however, been observed in England at different times ; 

 and it has now been admitted into the list of birds which 

 occur as occasional visitors to Britain. In this instance, 

 it is not improbable the birds may have escaped from 

 the collection of some neighbouring proprietor. 



Dr Smith was informed by Mr Sanderson, George Street, 

 that a flock of these birds, in a wild state, had this summer 

 frequented Loch Leven, where it is possible they may have 

 nested, and one of them had been sent to Mr Sanderson 

 for preservation.
