CLASS MAMMALIA. 



animal is perfectly liquid. When entirely cooled it assumes 

 a consistence like that of the pulp of a water melon, and 

 when completely concrete, it is crystallized and brilliant. 



Though this oily substance is found about the brain, it 

 is very distinct from it in nature and situation ; nor is it in 

 the head alone that it is found. It pervades the entire 

 body, but more especially all the fatty parts. It is con- 

 tained in a great number of very small vessels which ter- 

 minate in a canal improperly named the spermatic vein. 

 This canal follows the direction of the spinal marrow. Its 

 embouchure is in the brain itself, where it discharges new 

 quantities of this substance in proportion as the old is ex- 

 tracted. 



The ambergris to which we have above alluded, is a 

 portion of the excrements of the animal hardened by the 

 effect of disease and mixed with undigested aliments. It 

 is found in the intestinal canal in balls or irregular lumps, 

 sometimes to the number of four or five. 



The Cachalot Trumpo, (Catodon Macrocephalus, Linn.) j 

 has a head longer than the body; teeth straight and 

 pointed; body and tail elongated; a rounded eminence a 

 little beyond the origin of the tail. 



This Cachalot is found in the latitudes of Greenland, &c. 

 but particularly near the coast of New England and the 

 Bermudas. It is upwards of seventy feet in length, but is 

 more particularly remarkable for its enormous head which 

 occupies more than half of this length, and is an immense 

 reservoir of spermaceti. The jaws appear as if truncated, 

 and produce an appearance resembling the muzzle of a 

 monstrous bull ; eighteen large teeth are in the lower jaw 

 on each side, which are received into as many correspond- 

 ing alveoli in the upper when the mouth is closed. These 

 teeth are between seven and eight inches in length, and 

 are as white as the finest ivory. This animal though 

 sometimes about forty-three feet in circumference in the
