I had often heard of Mr. Fitzgerald's propensity to duelling.

He was still a little suspicious of his chum's propensity to tease.

This propensity he inherited not only from his mother, but also from his father, who had been a frontiersman.

He, had a propensity to talk about "his Pedro," as some men will talk of their dog.

Are you never able to restrain your propensity for making sport?

But Mr Bates considers that several kinds of bats have this propensity.

No more is needed to arouse his propensity to thrust with his back.

An instinct is a propensity prior to experience, and independent of instruction.

He then asked what length of time he had been known to possess that propensity.

Let the young avail themselves of this propensity, and make the most of it.
