to enter into a calculation of comparison with other parts of 
the kingdom. The commonest of the Cornish Bats are, l* 10 
Pipestrell, Lesser Horse-shoe and Long-eared, in the order 
in which they are enumerated ; but their local occurrem e 
depends more on the accident of their meeting with c^> n ' 
genial haunts, than on the mere influence of climate. fh e 
latter circumstance, however, produces its effect on the habits 
of these animals; so that in Cornwall, where what may 6 
denominated severely cold winters do not occur more 
quently than in cycles of six or eight years, the appearance 
of the Bat may be witnessed in every week, in an ordinary 
year. A fall below the 40th degree of the thermometer *<* 
the signal for their retreat; but. a slight change to a milder 
temperature restores them to activity, when not uncommon -V 
they may be seen at mid-day, in search of prey, which niigb 
not be obtained at the more usual hours of the evening. ^ 
It may be regarded as another proof of the mildness 0 ^ 
the climate, that the Longtailed Field Mouse (Mus Syl va ' 
ticus) breeds at, or even before, the beginning ot January • 
forming its nest at this time in ricks of hay. The Frog a» s 
is rarely later than this period in depositing its spawn. 
Of the genus Sores, Cornwall possesses three specie^ 
sufficiently distinguished. These are, Sorex Araneus, Jeny ,lS 
in the Magazine of Zoology , vol. 2 : the front tcetli a deep 
brown through most of their length; Bell's British Quad r*' 
j)eds,p. 109. Another species, S. Araneus of Duvernoy “ n 
Jenyns, Mag. of Zo., vol. 2, fig. 1, the snout not so long a * 
in the S. Araneus of English Authors : the body and ta 1 ^ 
longer; ears and tail different, the former being more me 81 ' 
branous, and very slightly furred; the teeth brown only® 
the tips of the lower front teeth ; and so generally of 111 
molars ; tail narrow at the commencement ; slightly hairc * 
and none beyond the tip. A third species is referred to 
Fodiens of Bell, p. 115; S. Bicolor of Jenyns, Mag. of* 0 ’’ 
vol. 2, p. 37; but it differs in some particulars which By 
require notice. Weight three drams, lifty-six grains; long 
of the body three inches, of the tail one inch and tm^ 
quarters. Nose somewhat flattened ; hind feet and t0 
ciliated, the fore feet less so. Under front teeth pU'y 
white; the upper slightly coloured; their crenations B 
exactly like any in Mr. Jenyns’ plate. j 
Of Quadrupeds now extinct, but which formerly ratify 
our hills, beside the Deer, of which the horns are often f° u ® 
in stream-works, and of which examples exist in the M'is ( yi 
of the Royal Institution at Truro, and in that of the R°y 
Geological Society at Penzance, remains have been i°“ , 6 
of a large animal of the Ox kind, and which I feel no sC Jf° g, 
in referring to the Bonassus described by Pliny, E lb ‘ ^ 
C. 15, as iu his day inhabiting the north of Europe.
