     Now, I still think that for this box of matches to have escaped the wear of time for immemorial years was a strange, and for me, a most fortunate thing. Yet oddly enough I found here a far more unlikely substance, and that was camphor. I found it in a sealed jar, that, by chance, I supposed had been really hermetically sealed. I fancied at first the stuff was paraffin wax, and smashed the jar accordingly. But the odour of camphor was unmistakable.

2. (figuratively) A strong, pervasive quality.
3. (figuratively, uncountable) Esteem.

   Synonyms: esteem, repute
