102 Mr. Gould on a new British Warbler. 
presented by him to the Horticultural Society. At first it appeared rather 
sickly, but after it had been kept in the hot-house for some time, it re- 
covered, and began to move about. It cannot now be correctly ascer- 
tained when it produced the first egg, but it was very shortly after its: 
arrival. I should think about the beginning of November. This egg 
was sent, by the desire of Mr. Sabine, to the Zoological Society. About 
the same time this year, it produced a second egg, and three weeks after- 
wards, a third ;* the latter was unfortunately broken by the animal itself, 
but the former is still in preservation. It fed upon lettuces and the tender 
leaves of cabbages ; the former seemed to be its favourite food. Sometimes 
it would devour two large lettuces, and then remain for days afterwards 
without touching food, or moving from its place, except when cold 
water was sprinkled upon it. During the day it was usually in a dormant 
state, in the shade : but towards the evening, when the house was moist 
and warm, it would spread itself out, and move from one part to another. 
It seemed to like moisture, and I haye no doubt that it might have been 
preserved for years, if it had not been accidentally killed. On Satur- 
day last it was at the end of the house where the fire comes in, and 
ventured too far upon the hot bricks after they had been watered. In 
the morning it was found fixed to them, and quite dead.

Art. XXII. On the occurrence of a new British Warbler. 
By Mx. Joun Gourn. In a Letter to N. A. Vicors, Esq. 
Sir, 
I HOPE to be excused the liberty I have taken in thus addressing to 
you, in the form of a letter, the following short account of the occur- 
rence of a European bird, which, as far as I am acquainted, is new to 
the British Fauna. 
When we consider that European ornithologists have enumerated in 
* These eggs were as large, and appeared to be as fully developed, as those 
produced by the animal in its native country. Two representations of these 
eggs are given in Tab. Suppl. xv, bis. f. 3, 4. Wis ae
