The Zoologist — April, 1867. 711 



there was scarcely a bird of the species to be found about the smaller creeks, where in- 

 deed it is at all times decidedly uncommon. The blackheaded is without doubt the 

 gull that commonly fullows the plough.— W. H. Poiver; Victoria Park Hospital, N.E., 

 March, 1867. 



Gulls vomiting their Food.— l have just read in the 'Zoologist' for March (S. S. 

 625) a letter f:om Mr. Blake-Knox, in which he stales that the common gull vomits 

 such portions of its food as are indigestible, in the shape of jelly. This would seem to 

 afford a little help towards the solution of a subject that has long been under my 

 notice, but which no one has hitherto satisfactorily explained. 1 have observed for 

 many years a translucent jelly lying on the " Heath," generally but not always within 

 a hundred yards of a small pond; sometimes I have seen it on dry grass, sometimes 

 on swampy, and not unfrequently on a small patch of rushes in the centre of this pond. 

 It first makes its appearance about October and remains till now ; it has no smell, and 

 can surely proceed from no quadrupeds, from being found in the middle of the pond 

 mentioned. The probability of its being any indigestible part of a bird's food seems to 

 me a little uulikely,as this would give one the idea of digestid food, being so clean, and 

 there are no ascertainable pieces of animal matter amongst it. I have never seen a 

 heron thereabouts, though I am always looking for birds there; and even if it proceeded 

 from one, what should a heron be doing so far from water as I sometimes see this? 

 and I never heard of or saw a gull of any sort in this particular locality. Some of the 

 readers of the ' Zoologist' may be able to assist me in my endeavour to arrive at a 

 satisfactory conclusion. — II. Grcemvood ; Sandfield Lodge, Hampstead, March 21,
