loose skin of the neck; and at the same time the cartilages opening into a wide 

 hoop, the whole tongue is drawn into the mouth. 



In fig. 5, A represents the skull; b the shallow crena, or groove, for the 

 cartilages ; c the place of their ending at the right nose-hole; d the orbit of 

 the eye; e the hole for the optic nerve ; f a hole or passage through from one 

 orbit to the other; g a bone covering the hole to the ear; h the lower jaw and 

 bill; i a ridge or processus in the skull, beginning at the root of the upper 

 bill, and keeping the two ends of the bony cartilages in their place on the 

 right side; k the os jugale; 1 the upper bill. 



Fig. 6, represents the right leg and foot, in which there are two digiti before, 

 and two behind. The strength, size, and sharpness of the hooked claws or 

 talons, are remarkable. 



Fig. 7, A represents the oesophagus; b the ingluvies or crop, partly muscu- 

 lous, and lined with a glandulous coat. This I found quite filled with small 

 black pismires; as also c the ventriculus or gizzard, which joined close to the 

 ingluvies; ddd the intestines nearly of the same size for the whole length; 

 e the beginning of the rectum; f the pancreas. 



Fig. 8, represents one of the middle pair of feathers of the tail, in which 

 the great strength of the quill, for so small a feather, and its bifurcate end, are 

 very remarkable. 



Fig. 9, represents the roof of the mouth, where it is observable, that the 

 rima or passage for the air to the nostrils, is beset on each side with a row of 

 10 or 12 small sharp teeth, with their points standing inwards, towards the 

 gula. These take the prey from the end of the tongue, whose barbs or prickles 

 are moveable, and are to keep it from going out of the beak again with the 

 tongue, and from hence it is conveyed to the swallow. 



The Natural History and Description of the Phoenicopterus or Flamingo ;* with 

 two Views of the Heady and three of the Tongue^ of that beautiful and un-

All authors, from Aristophanes down to Aldrovandus, have accounted the 

 phoenicopterus a bird of the palmipede or web-footed kind; and though the 

 latter author will not allow it to be so, yet he is obliged to own that it is not a 

 true fissipede or digitated fowl. Dr. Charlton only, among all the later natural

 occasionally appears in some parts of Europe. It is about the size of a heron, with the neck and 

 legs enormously long. 'J'he colour of the full-grown bird is scarlet, except the long wing-feathers, 

 which are black.
