go Dr. Philip’s experiments to ascertain the principle , &c. 
6 . That there is therefore in the most perfect animals a 
combination of three distinct vital powers, not immediately 
depending on each other ; one of the muscular system, one 
of the nervous system properly so called, and one of the sen- 
sorial system. See observations under Exp. 19. 
7. That the muscular system, though independent of the 
nervous system, is so influenced by it, that the power of the 
former may even be destroyed through the nervous system. 
Exp. 3, 2, 3, 4, 5, 6, 7, 8, 10, 11, compared with Exp. 38, 20, 
and 23. 
8. That both the muscular and nervous systems, though 
independent of the sensorial system, are so influenced by it, 
that they may even be destroyed through it. Exp. 8, 10, 11, 
17, and two last paragraphs under Exp. 19, compared with 
Exp. 20, 21, 22. 
9. That although in the less perfect animals we find the 
muscular life existing alone, and the muscular and nervous 
existing without the sensorial life ; in the more perfect ani- 
mals they are so connected, that none can exist long without 
the others. See the last paragraph under Exp. 19. 
10. That nutrition, circulation, and respiration, are the 
means by which they are so connected.
