AND SCHONBEIN 39 



current cannot be the true theory of the electric 

 battery or of the cause which renders it active. On 

 the other hand the contact theory, according to which 

 chemical affinities depend on the electrical state and 

 not vice versa, adequately explain the chemical 

 phenomena which the battery produces.

 Schbnbein to Berzelius 



DEAR SIR, 



I take the liberty of sending you, by favour 

 of Herr Schiitz of Summiswald, a paper 1 which you 

 have probably not yet seen, and whose contents will, 

 I think, not be wholly without interest to you. 

 Unfortunately, the accumulation of business has 

 prevented me from following up further the subject 

 which is there discussed ; and I have not had time 

 to prepare the odoriferous principle (which I may 

 mention that I have called ozone) in sufficiently 

 large quantities to be able to determine its chemical 

 properties accurately. As soon as I have the necessary 

 leisure I shall proceed at once to continue this 

 work, and shall in due time make the scientific 



1 The reference is probably to the paper: " Beobachtungen liber 

 den bei der Electrolysation des Wassers und dem Ausstromen 

 der gewohnlichen Elektricitat aus Spitzen sich entwickelnden 

 Geruch." Which edition is meant, whether AWiandl. der 

 Milnchner AJcademie, iii. 257, or Poggendorff, 50, 616, 1 cannot 

 say. In the Jahresbericht, xxi. (1842) p. 39, Berzelius refers to 

 the Annalen.
