in any way to the bodily or the mental vision; it is often pleasing,
harmless, or even useful.... A _delusion_ is a mental error or deception,
and may have regard to things actually existing, as well as to
_illusions_. _Delusions_ are ordinarily repulsive and discreditable,
and may even be mischievous."[27]

_avocation_, 'something aside from one's regular calling, a by-work.'"[28]
