must see, if for no other reason, more feebly, as their 

 organs of sight are always exerted. 



As for hearing, they are furnished with the internal 

 instruments of the ear, although the external orifice 

 no where appears. It is probable this orifice may 

 open by some canal into the mouth ; but this has not 

 as yet been discovered. 



It h likely that all animals of the kind can hear, as 

 they certainly utter sounds to each other. This vocal 

 power would be as needless to animals naturally deaf, 

 as glasses to a man that was blind. 



But it is in the circumstances in which they continue 

 their kind, that these animals shew an eminent supe- 

 riority. Other fish deposit their spawn, and leave 

 the success to accident ; these never produce above 

 one young or two at the most, and this the female 

 suckles entirely in the manner of quadrupedes, her 

 breasts being placed as in the human kind. 



Tn fishes of the whale-kind, the tail has a different 

 position .from what it has in all other fishes ; for 

 whereas in these it is erected perpendicular to the ho- 

 rizon, in them it lies parallel thereto; partly to sup. 

 ply the use of the hinder pair of fins, which these 

 creatures have not, and partly that they may be abb 

 to raise or depress their body at pleasure. For it be* 

 ing necessary they should frequently come to the top 

 of the water to take in or let out the air, they are pro. 

 vided with an organ to facilitate their ascent and de. 

 scent as they have occasion. And as for turning their 

 bodies in the water, they perform that as birds do, by 

 strongly moving one of their fins, while the other is 

 quiescent. 



The Norway whale is frequently sixty or seventy 

 feet long. His shape pretty much resembles that of a 

 cod; he has a large head and small eyes in proportion, 

 On the top of the head are two openings, through 

 which he spouts out the water (which he takes in as 

 he breathes) like a large fountain, which makes a 

 violent noise. 



His skin is smooth and not very thick : the colour
