LETTERS TO BROTHER JOHN. 281 



natural kinds of excitement is, because we have lost 

 a part of that excitement which is natural and 

 necessary to us. It results from a languid and lazy 

 circulation a gorged state of the venous system 

 with black, devitalizing blood ; and a deficiency of 

 that stimulating and vivifying blood, whose colour 

 is vermilion, and which is proper to the arteries. 

 Those distressing sensations of sinking, and want, 

 and languor, and low-spiritedness, of which dyspep- 

 tics complain, accrue to them from the same causes. 

 They are deficient in excitement they want excite- 

 ment ; they want to have their brains, and heart, 

 and whole system, stimulated, spurred, by the ex- 

 citing properties of vermilion blood, driven merrily 

 and forcefully to every point of the universal tissue. 



We require a stimulant, then, certainly ; but the 

 only stimulant which will serve our purpose is ar- 

 terial blood in energetic circulation : and the only 

 means to procure this is bodily exertion. " Exer- 

 ritium natures dormientis stimulatio, membrorum 

 solatium, morborum medela, fuga vitiorum, meditina 

 lanyuorum, destructio omnium malorum" 



One word more for bodily exertion, as the means 

 of increasing bodily strength; and without health 

 there cannot be strength. 



Observe the manner in which horses are trained
