Health," published by G. P. Putnam's Sous, s:iys : " The 

 effect of the nitrogen upon the brain is to c^nlrc ucrcc 

 force fredy, and this rules and regulates the actual force 

 which takes its origin in the respiratory foods consumed. 

 These respiratory foods furnish the force itself, but the 

 nitrogenized foods furnish the muni festers of force 1 .' 1 It 

 appears to us that the nerve force, which he says is 

 evolved, is all there is of it, save the requisite conditions 

 afforded by heat. Dr. Hough ton says : kk The hunted deer 

 will outrun the leopard in a fair open chase, because the 

 force supplied to its muscles by vegetable food is capa- 

 ble of being given out continuously for a long period of 

 time ; but in a sudden rush at a near distance, the leopard 

 will infallibly overtake the deer, because its flesh food 

 stores up in the blood a reserve of force capable of being- 

 given out instantaneously in the form of exceedingly 

 swift inuscualr action." Dr. Fotbergill goes on to say: 

 " Nitrogen is the essential factor in all explosive com- 

 pounds, from gunpowder to nerve force. It endows the 

 consumer of it with energy and enables him to discharge 

 his force quickly and rapidly." Again, he says of the 

 race-horse: "His food affects his speed and endurance, 

 and without his nitrogenized food he would cut a poor 

 figure at a race, because without it he could not discharge 

 his force fast enough."
