Sorry, no etymologies found.
Sunday morning I was so ill and weak I was obliged to lie down for an hour or two after breakfast, was much benefitted by my rest and well enough to eat heartily of roast duck at dinner, when Dr. McDonough joined us, he returned to the hospital in the afternoon but rejoined us after tea, to tell us goodbye, but while here he received letters from Dr. Furness (who is on a visit to Mt. Lebanon) telling him that Dr.F. had obtained leave for him to remain here until he came back, probably about Thursday.
