Quadrupeds. 3941 



April 22. One bat, in a sheltered place ; showers through the day, 

 in the evening wind North, and cloudy. 



April 23. Bats flying : wind W.N.W., cool. 



April 25. No bats at T and homeward : evening cold. 



April 28. Early in the evening a bat flew straight outward through 

 our harbour from the town, to Scilly Cove, and did not appear again. 

 Later in the evening bats were numerous, in places long forsaken by 

 them, flying in long curves. Weather mild and cloudy. 



From this time the bats have resumed their summer habits, but 

 seem still influenced by the weather, as on : — 



May 7. No bats : cold showers, wind North. 



May 11. No bats : clear, cool, wind N.W. 



May 16. Bats now take long and active flights, and in such num- 

 bers, as to show that hitherto those which have appeared could only 

 have been a small proportion of such as lay hid. With such frequent 

 and long interruptions of flight, is it possible to suppose that the chief 

 part of their sustenance can be obtained on the wing ? 



May 20. No bats : a fine evening, calm and warm, bright moon- 

 light. I observe that bats do not continue to fly later when the moon 

 shines brightly, but their absence this evening is remarkable. 



May 21. Bats flying, but they disappeared earlier than usual ; I 

 saw none after the moonlight prevailed over the day. A fine evening, 

 wind East. 



May 30. No bats : yet the evening is fine and calm, although yes- 

 terday, when the weather was cool, and the wind East, bats were in 

 flight. 



June 5. Only one bat seen for a moment, after 9 o'clock : weather 

 calm, overcast. 



The following notes from other parts of my journal will further tend 

 to illustrate the habits of different species of bats. 



January 11. A specimen of the larger horse-shoe bat brought to 

 me, taken as it was in flight, and proving that this species does not 

 leave us in the winter. 



Several specimens of the lesser horse-shoe bat have come into my 

 possession, and I observe that both the ears and horse-shoe membrane 

 on the nose are very sensitive and movable. The weight of one spe- 

 cimen was 77 grains, of another, 74 grains, of another, 73 grains ; ex- 

 tent of wing 9 inches and 3-tenths. When at rest, this species turns 

 up its tail over its back : it is exceedingly beautiful when closely 

 folded up in its wings.
