.All animals in a domedic date become varioufly 
marked, and from being better fed will be in- 
creafed in fize ; thefe differences by attention may 
be rendered conftant, and varieties without end 
may, by culture and attention, be procured from 
one fpccies. This is indanced in white Turkeys, 
white Ducks, Ducks and Fowls that are creded, 
but in no birds does it prevail in a greater extent 
than amongft Pigeons, which, being very prolific, 
that is breeding very fad, would naturally be¬ 
come the mod: varied. Some perhaps have been 
felected on account of their fuperior fize, and from 
thefe a larger race has been produced; others on 
account of particular marks have been matched 
together, and thefe marks have become perma¬ 
nent or lading. Others again, on account of foinc 
of their feathers growing in a particular form, or 
taking a particular direction. Mod of thefe, in 
the fird indar.ee, were only accidental varieties, 
the confcquence of their becoming domedic.
