Defcription given by John "Daniel Major , and pub- 
lifh'd in the Mifcell. Academ . Nat . Curiof Dec. i. 
An. 3. p. ii. & feqq» This Hole opens into the two 
Canals which run through the Skull to the Palate, and 
are called by Major , DuElus hydragogi. They did 
not remark in the Skin any Opening or Outlet for the 
Excrements 5 and I have been told-, that this Narhual 
voided them through this Hole on the Top of the 
Head.

It rather ferves the Fifh for Peeking its Food. A Cap-

ftuck this Tooth into the Whale's Belly, up to its 
Mouth, and had fuck'd the Blood and Humors.

of this Narhual 5 for I have only feen the Huff'd Skin, 
and confequently the outward Shape, as it was carry- 
ing to Leipjic Fair, and on the way {hewn here at 
Hanover . And as I find that the Figure engrav'd and 
printed at Hamburg , has a good Likenefs to what J 
have feen, I have hereto annexed a Print of it.
