[127] Compare Havelock Ellis, _Studies in the Psychology of Sex_,
vol. vi.; _Sex in Relation to Society_ (Philadelphia, 1910, p.
368); "But altogether outside theoretical morality, or the
question of what people 'ought' to do, there remains _practical
morality_, or the question of what, as a matter of fact, people
actually do. This is the really fundamental and essential
morality. Latin _mores_ and Greek [Greek: ethos] both refer to
_custom_, to the things that are, and not to the things that
'ought to be.'" The etymological connexion, of which Dr. Moll
speaks, between the words _morality_ (or _ethics_) and _custom_,
thus subsists through the intermediation of the dead languages.
But in German, the etymological connexion between _Sitte_
(custom) and _Sittlichkeit_ (morality) is immediately
apparent.--TRANSLATOR'S NOTE.

[129] It is surprising that the author makes no reference to the
close association, in many cases, of the sentiment of disgust
with unpleasant smells. The earthworm, the cockroach, and the
bed-bug are regarded as peculiarly disgusting, and all have a
particularly offensive odour. The unpleasant smell of the alvine
evacuations is assuredly a large element in the disgust these
inspire.--TRANSLATOR'S NOTE.
