"Queen: Nothing at all, yet all that is I see."

hamlet, William Shakespeare

his tongue, i believe, was bloody and hanging out of his mouth.

he looked as if he were hungry.

he has several wolf-like qualities; a gray coat, sharp claws and yellow fangs.

as i reached for a stick, he moved to the other side of the hill.

panting and hungry, he looked at me, a defenseless human and he snarled.

well i said my prayers, however, he simply turned and limped off. 

queen elizabeth's purpose in the passage is;

d. to persuade the troops that she is a capable commander

"i have the heart and stomach of a king. i myself will be your general, judge, and rewarder."

voltemand and cornelius bring to claudius the news that the king of norway has ordered fortinbras to stop his attack.
