Up the nostrils of such asses as were hard worked: for tiiey, 
being naturally straight or small, did not admit air sufficient to 
serve them when they travelled, or laboured, in that hot climate. 
And we know that grooms, and gentlemen of the turf, think 
large nostrils necessary, and a perfection, in hunters and running 
horses. 
Oppian, the Greek poet, by the following line, seems to have 
had some notion that stags have four spiracula

goats breathe at their ears ; whereas he asserts just the con-

LETTER XV. To T. PENNANT, Esq. 
DEAR SIR, Selhorne, March 30, 1768. 
Some intelligent country people have a notion that we have, in 
these parts, a species of the genus 
musfelinum, besides the weasel, stoat, 
ferret, and polecat ; a httle reddish 
beast, not much bigger than a field 
mouse, but much longer, which they 
call a cane. This piece of intelli- 
gence can be little depended on; 
but further enquiry may be made.* 
* That a fourth species of the subgrenus putorius (subordinate to mvsteln) , the group to which 
Mr: White here refers, exists in England, 1 have found to be a very common opinion in the 
southern counties. I have repeatedly heard of it in Surrey, where it is denominated a kine, and 
it has often been described to me as being very similar to the common weasel, but much smaller, 
the usual argument adduced for its distinctness being, that it has frequently been observed with 
young ones. The fact is, there is considerable disparity of size between the sexes of the common 
weasel, the female being much smaller than the male, so much so as to have given rise to the 
above supposition. We have but three species, nor does western Europe produce more: the fitch- 
weasel, "polecat,'* or "foumart"^ {muslela-putorius furo) , which in its domesticated state is 
termed the " ferret," the stoat-weasel or " ermine" {imtsMa-putorius erminus), and the " com- 
mon," or (as it might be better termed), the dwaif-weasel {musteln-pittorius vulsraris), all of which 
are plentiful throughout the country. Of the typical muslelcB we have the white-breasted marten
