76 Whitaker: Notes on the Breeding Habits of Bats. 
The Daubenton’s Bat referred to (No. 9 on the list) was one 
of a party of four, which were feeding at dusk, on June 18th, 
1900, over the surface of the Serpentine in Stainbrough Park. 
I succeeded in netting it as it approached near to the side. 
This was at about ten o’clock at night. 
The following morning, at about eight o’clock, I found it 
hanging in the corner of the cage in which I had placed it the 
previous evening, and under its right wing was a ‘baby,’ to 
which it had given birth during the night. The young one was 
of a dark purplish flesh colour, the wing membrane being only 
very slightly darker in colour than the skin of the rest of the 
body. It was blind, and naked save for a few fine, straggling 
hairs on the muzzle. It clung tenaciously to its mother during 
the whole time it lived (except when I separated them to photo- 
graph), and was calling continually with a very soft, ‘sucking’ 
kind of chirrup, scarcely audible at a distance of a few feet, and 
very diffierent indeed from the loud, deliberately repeated call 
of a baby Noctule. 
The mother quite failed to give her young one any attention, 
and when, at dusk of the night following her capture, I 
endeavoured to feed her, she obstinately refused to take the 
least particle of food or drink. Upon examination, I found the 
reason for this was that her tongue was inflamed and much 
swollen, from what cause I do not know. The bat was evidently 
in a ‘bad way,’ and I found I could do nothing for it, and con- 
sequently was not surprised, though much disappcinted, to find 
next day that both the young bat and its mother were dead. 
The relative sizes of the young female and its mother (given 
in inches and decimals of inches), measured carefully im- 
mediately after death, were as follows :—

On Plate X. are reproduced four photographs of the bat 
with its one-day-old youngster by its side, taken by my friend 
Mr. Wakefield. 
The most interesting observations which I have been able to 
make during the past season were made in connection with two 
Pipistrelles referred to on the foregoing list as Nos. 4 and 5. 
During the early part of June I took a short holiday in the 
New Forest, Hampshire, and on the day previous to my return 
I met a gamekeeper, who, in answer to inquiries of mine,
