LECTURE IV. 153 



naturalists of Europe, the teeth, or spiral horn- 

 like processes, were held in very hign estimation, 

 as the supposed horns of Unicorns. Various 

 medical virtues were attributed to them, and they 

 were even numbered among the articles of regal 

 magnificence. At Rosenberg in Denmark is said 

 to be still preserved an ancient throne, composed 

 of Narwhals' teeth, and which was once the seat 

 of state of the ancient Danish Monarchs. 



I purposely omit speaking of the supposed 

 different species of this genus; their description, 

 as yet, being not sufficiently accurate to justify- 

 any very clear conclusions. 



Having thus taken a general view of the Mam- 

 malia or viviparous quadrupeds, we shall in our 

 next Lecture proceed to Birds.
