His feeling equal to such a fatigue is a good sign, and his feeling no fatigue in it.

"Naughty Charles did not come on Tuesday, but good Charles came yesterday morning. About two o'clock he walked in on a Gosport hack. His feeling equal to such a fatigue is a good sign, and his feeling no fatigue in it a still better. He walked down to Deane to dinner; he danced the whole evening, and to-day is no more tired than a gentleman ought to be."

This is from Jane Austen's letter to her sister Cassandra(http://book.99csw.com/book/136/4400.htm).
I'm having trouble to understand the bolded part. Can anyone help me to interprete it?

There's a typo in the quote. I've fixed it above.
