414 On the Theory of Mixed Gases. 



*' be one-fourth part d Schmidt's number, I 

 " shall give up the theory as indefensible ; till 

 ** then I may be allowed to wave all arguments 



" drawn from his experience. Your in- 



" ference from your experiment I disallow... 

 ** I am sorry, that you and some others have 

 " misunderstood my language ; though it ap- 

 " pears to me to be your fault rather than ^ 

 *^ mine. The expression alluded to is this : 



* The particles of A meeting with no repul- 



* sion from those of B, further than that re- 



* pulsion which as obstacles in the way they 



* may exert, would instantly recede from 



* each other as far as possible in their circum- 



* stances, and consequently arrange th^m- 



* selves just as in a void space.** You seem 



* to understand it thus, * The particles of A, 



* meeting with no repulsion from those of B, 



* would instantly recede from each other as 

 ' far as possible in their circumstances, and 



* instantlij arrange themselves just as in a void 



* space.* Whereas my meaning was, ' The 



* particles of A, meeting with no repulsion 



* from those of B further than that repulsion 

 ' which as obstacles in the way they may 



* exert, the amount of which can only be as- 

 ' certained by experiment, would instantly 



* recede from each other as far as possible in
