" but the captain had gradually become blase'; the prospect of a speedy marriage cooled him more every day. Moreover, he was of a fickle disposition, and, must we say it, rather vulgar in taste. Although of very noble birth, he had contracted in his official harness more than one habit of the common trooper. The tavern and its accompaniments pleased him. He was only at his ease amid gross language, military gallantries, facile beauties, and successes."

This word was often seen fifty years ago, not so often now.
AHD says it is from French dialectic "blaser" for which it gives definition "cloy", again a word not seen very often.

Etymology of "cloy" is interesting. Would you believe it comes from French word "clou" = nail"?
Cloy \Cloy\ (kloi), v. t. [imp. & p. p. Cloyed (kloid); p. pr.
& vb. n. Cloying.] [OE. cloer to nail up, F. clouer, fr.
OF. clo nail, F. clou, fr. L. clavus nail. Cf. 3d Clove.]
1. To fill or choke up; to stop up; to clog. [Obs.]

2. To glut, or satisfy, as the appetite; to satiate; to fill
to loathing; to surfeit.

[Who can] cloy the hungry edge of appetite By bare
