parts of the vegetable and animal creation are 
“'•tied, supported, and increased. 
These fluids being more and more compounded, 
the vegetables and animals become more perfect, 
coagulated, and form a regular series. The sap 
many plants does not coagulate spontaneously, 
*' made to undergo this change by adding the 
®*tract of Goulard ; the sap of such plants is consi- 
®d as the most simple. In the onion there is a 
spontaneous coagulation. In insects the blood coa- 
^olates, but is witbout colour; in the amphibia co- 
ff superadded. The moving powers of animals 
0® the simple straight muscle, to the most com- 
'oated structure of that organ, with the different 
^plications of elastic ligaments, form a second series. 
® growth of bone, horn, and shell, come next in 
•■•ler ; joints, wliich admit of free motion, 
^I'is subject. 
, ne second class begins with those animals of the 
l^ind, which receive nourishment, like vege- 
from their external surface, having no mouth. 
follow those which are sinjply a bag or sto- 
^itb one opening, as tlie polypus, having no 
^ tans of generation, as every part of the bag is en- 
^'•"'ed with that power. In the leech, the structure 
Com niore complex : for although the animal is 
gan^°*^^ nf a bag with only one opening, the or- 
d°^ Sc^cration, brain, and nerves, are super- 
, ’ thence a gradual series is continued to
