 vies with that of ftone in fome : in others, the 

 pliancy is equal to cartilages. Some are hollov/ 

 and filled with marrow ; others folid and maffy 

 throughout. Certain bones confift of a fingle 

 piece, while various parts connected together 

 form others. Laflly, ail thefe animals have the

 Tior part of fome into a pointed beak, a flender 

 fnout, or a long and monilrous trunk ; or en- 

 larging it to form a hideous head, frightful to be-= 

 Jhold., or exciting pleafure by its refemblance to
