cures by the efficacy of these concretions ; often prove fatal

Condoma, anomalous animal of the goat kind ; its description, 

 ii. 289. 



Condor possesses, in a higher degree than the eagle, all the 

 qualities that render it formidable to the feathered kind, to 

 beasts, and to man himself; is eighteen feet across the wings 

 extended, according to Acosta, Garcillasso, and Desmar- 

 chais ; the beak so strong as to pierce the body of a cow ; 

 two of them able to devour it ; they do not abstain from man 

 himself; fortunately there are few of the species ; the In- 

 dians believe that they will carry off a deer, or a young calf, 

 in their talons, as eagles would a hare or a rabbit ; and that 

 their sight is piercing, and their air terrible; that they seldom 

 frequent the forests, as they require a large space for the dis- 

 play of their wings ; they come down to the sea-shore at 

 certain seasons, when their prey fails upon land ; they then 

 feed upon dead fish, and such nutritious substances as are 

 thrown upon the shore ; their countenance not so terrible as 

 old writers have represented ; those who have seen this ani- 

 mal, say the body is as large as that of a sheep ; many in- 

 stances of its carrying away children ; circumstantial account 

 of this bird by P. Feuillee, the only traveller \fho has ac- 

 curately described it ; countries where it is found ; in the 

 deserts of Pachomac, where it is chiefly, men seldom ven- 

 ture to travel ; its flesh as disagreeable as carrion, iv. 82. 



Conepate, an animal resembling the skink in all things except 

 size, iii. 95. 



Congelation, the heat of blood in man, and other animals, is 

 about thirty degrees above congelation ; but in the marmot 

 and other animals which seem to sleep the winter, the heat 

 of the blood is not above ten degrees above congelation, iii. 

 1.59.

 countered in this voyage, iv. 350.
