Gulliver’s Travels

From the text:

I was in the utmost astonishment, and roared so loud, that they all ran back in a fright; and some of them, as I was afterwards told, were hurt with the falls they got by leaping from my sides upon the ground. 

I answered in a few words, but in the most submissive manner, lifting up my left hand, and both my eyes to the sun, as calling him for a witness; and being almost famished with hunger, having not eaten a morsel for some hours before I left the ship, I found the demands of nature so strong upon me, that I could not forbear showing my impatience (perhaps against the strict rules of decency) by putting my finger frequently to my mouth, to signify that I wanted food.
