 by the production of innumerable animalcules j a clear 

 proof that it contains organic matter, otherwise it could not

 the lungs and skin gave out organic matter, which is in 

 itself a deadly poison, producing zymotic and epidemic dis- 

 ease according to its strength. So potent is it for injury, 

 that if a drop of the liquid matter obtained by the conden-

 remedies for this evil, acting not as miracles, but in accord-

The lighting of stables is a matter of much moment 

 for the maintenance of health, and the prevention of dis- 

 ease among men and horses. We are told that institutions 

 of the old world can show by statistics, the immunity from 

 disease of the inmates on the light side of the building,
