they arc very deep, and fhorter in proportion than 
carp, but of a very hardy nature. 
The mules between carp and tench, partake of the 
nature of both fifli, come to a good lize j but fom# 
part of their body is covered with the fmall dimy 
fcales of a tench, and fome other part has the larger 
fcales of carp 5 their fleili approaches nearer to that 
of a tench, and they are likewife of a lefs tender na- 
ture than the common carp : this latter kind of mule 
is called in Germany fpiegel karpe^ i.e. the mirror ~carp^ 
the blotches with large fcales among the fmaller ones 
being confidered as mirrors. 
Whether thefe mules are capable of propagating 
their fpecies, I cannot affirm ; never having made 
any experiments on that fubjedt ; nor have I heard 
any thing faid on that head with any degree of pre- 
cifion, or founded on experience. In fome ponds 
in Lancaihire, I was told, by a gentleman of great 
worth and honour, both thefe kinds of mules are 
now and then found. 
I think it, however, not advifeable, to put carp and 
tench, or carp and crufians, in one pond, unlefs it be 
done for experiment’s fake; in which latter cafe, a 
fmall pond, free from other fiffi, with one or two fiffi 
of each kind, will be fufficient to gratify curiofity, 
without debafing a generation of carp in a large 
“ fomewliat refemblirtg a roach, with his red fins ; but it Is 
near as big as the larpeft carp, and much better meat.”
