Green Eagle, not so big as a splacknuck (an animal in that country very finely shaped, about six foot long) and in every part of the body resembling a human creature, could speak several words, and perform.    From Wordnik.com.  [Gulliver's Travels] Reference

His Majesty, a prince of much gravity, and austere countenance, not well observing my shape at first view, asked the Queen after a cold manner, how long it was since she grew fond of a splacknuck; for such it seems he took me to be, as I lay upon my breast in her Majesty's right hand.    From Wordnik.com.  [Gulliver's Travels] Reference

It now began to be known and talked of in the neighborhood, that my master had found a strange animal in the field, about the bigness of a splacknuck, but exactly shaped in every part like a human creature; which it likewise imitated in all its actions; seemed to speak in a little language of its own, had already learned several words of theirs, went erect upon two legs, was tame and gentle, would come when it was called, do whatever it was bid, had the finest limbs in the world, and a complexion fairer than a nobleman's daughter of three years old.    From Wordnik.com.  [Gulliver's Travels] Reference
