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 have 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. XXll. On the occurrence of a neiv British Warbler. 

 By Mk. John Gould. In a Letter to N. A. Vigors, Esq. 



Sir, 



I HOPE to be excused the Hberty 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. xvi, bis. f. 3, 4. W. J .B.
