which will evaporate the water of the cossettes, should be at the 

 highest possible temperature in order to work economically; the 

 second is that the cossettes cannot move in an opposite direction 

 to the gases, but, on the contrary, they should circulate with 

 them until they leave the apparatus. The second principle is a 

 natural outcome of the first, as it is evident that gases at the

temperature at which they enter the apparatus (not less than 

 400 to 750 C. at first it was argued if the temperature was 

 above 500 C., the cossettes would be burned), would imme- 

 diately ignite if they were circulating in an opposite direction. 

 As to the moist cossettes that come in contact with 'these hot 

 ases, their temperature can never attain 100 C. so long as they
