caftrated male or fpayed female. Of the firft we may 
inftance the fnail, which is of both fexes, and has but 
one character, but that of the joint character of both 
fexes. 
But where the fexes are feparate, and in fpecies which 
have two characters, neither of them can be called the 
true one ; the true diftinguifhing properties being thofe 
peculiar to neither fex, which are found in the caftrated 
male, the fpayed female, or the monftrous hermaphro- 
dite. That this is the diftinCt character of fuch animals 
is evident, for the caftrated male and the fpayed female 
have but one fet of properties between them ; and when 
I treated of the Free-martin, which is a monftrous her- 
maphrodite, I obferved, that it was more like the ox than 
the cow or bull, fo that the double fex which contains the 
true character of every animal is imitated when made 
of no fex by art, and by that means gives us the true 
properties of the fpecies. 
. In the Free-martin the character arifes from a mixture 
of fexes ; but in fome animals, which have fecondary 
principles peculiar to the two fexes, we have a deviation 
from all thofe genera! rules. We have in fome a change 
of thofe fecondary characters, the perfect female with 
refpeCt to the parts of generation, afliiming more or lefs 
of the fecondary character of the male,
