it is they that are thus related to the brain. The 

 bones of the brain are the brain-case or cranium, the 

 flesh of the brain, the face or countenance. On the 

 head, bones and flesh have been disposed in the strictest 

 manner according to their dignity or worth. Poste- 

 riorly there is almost pure bone, in front almost pure 

 muscle. 



2066. The cranium can be none other than the ver- 

 tebral column continued around the brain. It consists 

 of three vertebrae, the face of one. This will become 

 clear in what follows. 



2067. If the bones of the head are the repetition of 

 those of the trunk, so also must the flesh of the head be 

 a repetition of that of the trunk. Pectoral and abdo- 

 minal muscles are ennobled in the muscles of the face. 



2068. The face must have been principally formed by 

 the orifice of the intestine- the mouth, and by the open- 

 ing of the lungs the nose, and by the apex of the vas- 



which are repeated as jaws. 



The mouth is the stomach in the head, the nose the lung, 

 the jawsjbe arms andjefik.. 



2069. The salivary glands are the liver in the head, 

 as the mouth is its stomach. The liver that was origi- 

 nally also symmetric in form has become wholly sym- 

 metric in the higher organized head and forms two 

 glands. The salivary ducts are the hepatic or biliary 

 ducts. 



2070. The tongue is the oesophagus elongated upon 

 the anterior side, because in front there is more flesh. 

 The tongue is the extremity of the intestine converted 

 into muscle. 



2071. The nose includes pectoral muscles, the mouth 

 arthric muscles or those of the limbs. 



2072. If pectoral and abdominal muscles are repeated 

 in the face, so also must the anterior bones, ribs, and 

 limbs be repeated. It will be shown, in treating of the 

 organs, that the nose is a vertebra, the jaws members, 

 and their muscles those of the limbs. The head is the 

 whole trunk with all its systems. The brain is the spinal
