the gauchos were accustomed to take the lining of 
the rhea’s stomach, dried and powdered, for ailments 
caused by impaired digestion ; and the remedy is 
popular still. Science has gone over to them, and

throat and under- surface dull white. The body is 
lumpy, and about the size of a large man’s fist. 
The eyes, placed on the summit of a dispropor-

tuberances, capable of being elevated or depressed 
at pleasure. When the creature is undisturbed, the 
eyes, which are of a pale gold colour, look out as

on the head or menaced, the prominences sink down
