dispersing, the bats reappeared near the house in September. The 

 same thing happened in 1882, and again in September, 1887 — after 

 absence from the previous May and June. 



The following notes were referred to by Mr. Dowker, taken from 

 his memoranda, as proving the regularity of their appearance, viz. : — 



May 21, 1890. — Counted seventy-eight Bats emerge from the house 

 at 8 p.m., returning to their dormitories at 9 p.m. May 23. — One 

 hundred and sixty Bats from the house at 8 p.m. May 26. — One 

 hundred and seventy eight Bats at 8 p.m., and twenty-seven more at 

 8.15 p.m. 



After disappearing from the house in June a few were noticed to 

 hang about some elm trees in the parish towards night, as if they took 

 to them for rest by day, but finally they entii'ely left the neighbourhood. 

 The entire disappearance of the Bats from June till September could 

 only be accounted for on the supposition that they migrated. 



Mr. Dowker quoted several notices of the migration of the Noctule, 

 recorded in the Zoologist — especially one by Mr. Wm. Jeffery, in Sussex, 

 who noted a great increase in the number of the Noctules in August, 

 and he supposed they were moving southward then. And Mr. A. J. 

 Clark Kennedy observed, about 5th of May, a flight of large Bats going 

 steadily in a north-easterly direction at Little Glenham, in Suffolk. 



The interesting account of the habits of the Ifoctule Bat, published 

 in the proceedings of the Zoologist Society, by Mr. Daniel, in 1834, in 

 reference to their growth and reproduction, was likewise quoted. 



Mr. Dowker recorded his observations on the " Long-eared Bat " 

 fFlecotus auritusj, mentioning that multitudes of this species hibernated 

 in an old farm house at Knowlton Court, where they even hung from 

 the rafters in clusters ; so much so, that he hived a number in his hat 

 like a swarm of bees. On one occasion, seeing two of these bats 

 flying about his room, he captured them and placed them under a bell 

 glass for future observation ; nest day, to his surprise, he found four 

 instead of two under the glass, but they were all dead. On examination 

 it appeared there were two female Bats and two young ones; the latter 

 had evidently adhered to their parents by the nipples of their teats. On 

 measuring their expanse of wings it was found that the mature bats 

 measured ten inches, while the young measured eight, so there was no 

 great difference in their si^e. The ears of the young ones were doubled 

 back. This species of Bat is common in Kent. 



Vesperugo serotinus, a Bat which exceeds in size the I^octule, was 

 the next species described. It was said to be tolerably abundant at 

 Stourmouth. It probably frequents hollow trees. In a note on this Bat 

 in the Zoologist, 1887, it is stated on the authority of LordLifford that it
