seem by this to prefer nesting on islands and flat ground to the pre- 

 cipices, when they have a choice: I did not observe one nesting on 

 the precipices. The larger gulls, being wary, are not often caught: 

 occasionally one is caught in the steel traps set for the puffins, but 

 they are not sought for their feathers. 1 did not observe any immature 

 gulls of any kind whatever at Ailsa Craig. 



Great Blackbacked Gull. — A few pairs nestle on the upper part of 

 the Craig, in similar situations to the two last mentioned. I did not 

 observe either the common or blackheaded gulls : the locality is not 

 suitable for their breeding haunts. 



Peregrine Falcon. — I was told that a pair annually nest on an 

 inaccessible ledge on the highest precipice of Ailsa, called, if I 

 mistake not, "Ashy-doo," but I did not observe them during my 

 last visit. 



Haven. — Several pairs of ravens nest on the inaccessible ledges, 

 finding abundance of food in the dead sea-fowl, &c. 



Gruuse.—A weathered egg in the yelk was brought to me by the 

 cragsman : it was found by itself on the turf near the summit of the 

 Craig, showing that grouse sometimes fly across from Ayrshire, but 

 there being no heather they do not stay. 



Shag. — Three or four pairs nest on the ledges of the highest 

 precipice : their favourite fishing station is a flat rock at its foot 

 called the " Scart Rock." The shags were formerly more abundant 

 than now. 



Stormy Petrel.— Fellow-members of the Glasgow Natural History 

 Society have told me that they have found this petrel under the huge 

 fallen masses of rock on the shore, and have also observed them in 

 the evening flying about at sea. 



The above list is far from being perfect, a great number of birds 

 nesting and frequenting the Craig which I have not enumerated, 

 besides occasional visitors ; but the above is the substance of notes 

 writteu at the time, and I hope at some future period to be able to 

 give a further list.

Bos scot icus.— -Seeing Mr. Alston's account of these cattle at Cadzow (Zool. S. S. 



669), I inquired of my friend Mr. J. M , late of Chartley Hall, concerning 



these cattle in the park at Chartley. He informed me that during several seasons 

 they had not bred, owing to the superabundance of bulls; and having introduced
