THE VETERINARY ART IN INDIA. 
the stimulant powers are equal to the quantity of excitability ; 
that is, the fullest proportion of stimulus is exciting an equal 
quantity of the excitability, and the powers of life are then at 
their highest. After this period the order is reversed ; for no 
stronger excitement being produced, and those already employed 
becoming habitual, lose their influence, and infirmity, debility, 
loss of appetite, and decay of the passions, are induced ; while 
the property of excitability, nearly exhausted, requires the strong- 
est stimulants to excite it, which not being produced, it ceases 
to act altogether, and death is the immediate consequence. 
As a still further explanation of this system, I will endeavour 
to describe it in another view, similar to what, I believe, is done 
by Dr. Brown, in his Elements. 
The excitability is supposed to be a stated quantity of a pro- 
perty which every animal must possess necessary to life. This 
is reduced to a scale of eighty degrees (see plate 1, Jig . 1) 
No. 80 is life commenced. No. 40 is life matured, and No. 1 
is life consumed.
