The Camelcon at London, was of several colours, 

 like a mottled colt. The most discernable were, a 

 green, a sandy yellow, and a liver colour. When 

 stirred or warmed, it was suddenly full of black spot> 3 

 as big as a large pin's head. But when it was quiet, 

 they gradually disappeared. 



There are four species of Cameleons, 1. The Ara- 

 bian, about the size of the green lizard. This is of a 

 whitish colour, variegated with reddish and yellowish 

 spots. 2. The Egyptian which is of a middle hue, 

 between a whitish and a faint green. 3. The Mexi- 

 can. And, 4. A kind which has been frequently 

 shewn in Europe, and diflers from all the rest. His 

 head is large, but he alters his body at pleasure, in- 

 flating it more or less, and not only his body, but 

 his legs and tail. This is peculiar to him. The b jdy 

 thus puffed, up, will remain so two hours* But it 

 is insensibly sinking all the time. It can continue a 

 Jong time in either of these states, but is generally 

 uninflated. It then looks miserably lank and lean, 

 its back. bone may be seen perfectly, its ribs counted, 

 and even the tendons of the feet distinctly seen through 

 the skin. 



Its mouth is furnished with continued denticulated 

 bones ; but it does not appear what use they are of, 

 since it preys oa ilies aud swallows them whole, 

 unless for holding a stick in its mouth cross- ways ; 

 which according to TElian, he frequently does., to 

 prevent being swallowed by serpents. 



The structure and motion, of his eyes are surpris- 

 ing. They appear to be large spheres, ot which oue 

 half stands out of the head, and is covered with a 

 thick skin, perforated with a small hole at top. 

 Through this is seen a very vivid aud bright pupi], 

 surrounded with a yellow iris. This hole is a lon- 

 gitudinal slit, which" he opens more or less ai . plea- 

 sure. The motion of its eyes is not less singular- 

 It can turn them, so as to see either forward, back- 

 ward, or on either side, without moving the head at 

 all/ which is fixed to the shoulders. And he can give
