THE MAMMOTH CAVE. 47 
The only instance that history (possibly 7o0- 
mance) records, so far as is known to the writer, 
in which these disagreeable effects of the ordi- 
nary atmosphere were markedly produced, was 
in the case of the unhappy Caspar Hauser, who 
_ was confined in a subterranean dungeon at Nu- 
remberg from infancy to adult age. When he 
was finally brought upon the surface of the 
earth, his life was rendered miserable by the 
insufferable odors that constantly impressed his 
olfactory nerves. ‘The smell of flowers, that to 
others were sweet, was so intensified in his case 
as to be exceedingly disagreeable. He was 
unable to pass a grave-yard, where others could 
detect no odor whatever, without fainting from 
the painful impression received through the 
sense of smell. This shows that, to appreciate 
“country air,” our senses must be adapted to it 
by constant contact.
